Description
Technical field
The invention belongs to the nickel-base alloy technical field, relate to a kind of oxide particle and strengthen cladding alloy powder and preparation method thereof, particularly a kind of oxide particle strengthens laser melting coating high wear-resistant nickel base alloy powder and preparation method thereof, and this high wear-resistant nickel base alloy powder is applicable to laser melting coating high abrasion operating mode component.
Background technology
In the daily life and industrial production in modern times, the attrition and attack meeting of metallic substance appears at every field, one of two large major ways that destroy component of machine, engineering component, corrosion will cause a large amount of consumption of mechanical component, and wearing and tearing then are to cause one of major reason of mechanical component inefficacy.They have also wasted ample resources in a large amount of metallic substance of loss, occupy very large proportion in financial loss.
The inefficacy of the engineering component that high temperature, burn into friction and wear cause occurs in the surface mostly, and this phenomenon impels the Materials science worker to the very big concern of material surface, and impels the fast development of material surface modifying technology.People wish to make material surface obtain higher, specific use properties when material monolithic keeps enough toughness and intensity, as wear-resisting, anti-corrosion and anti-oxidant etc.
It is reported that at present, in whole world industrialized country, the energy that consumes in wearing and tearing accounts for 1/2nd of total energy, 60%～80% component of machine is arranged approximately owing to wear and tear and lost efficacy.A highly developed industrialized country, the annual financial loss that causes because of wearing and tearing almost accounts for 1%～2% of total value of production in national economy.For example, the U.S. every year on average since the financial loss that causes of wearing and tearing up to 20,000,000,000 dollars; The financial loss that Britain is caused by wearing and tearing every year on average is above 51,500 ten thousand pounds.In China, the financial loss that is caused by wearing and tearing is equally also quite serious.Only according to department's rough Statistics such as oil, chemical industry, coal, electric power, agricultural machinery, just there is steel consumption up to millions of tons every year in China in wearing and tearing, and financial loss reaches 200～30,000,000,000 yuan more than.Thus, the effect of attrition of metallic substance performance quality and the work-ing life of mechanical component, and then affects the competitive capacity of these mechanical component on market.
Simultaneously, the metallic corrosion problem also spreads all over the national economy every field, from the industrial and agricultural production that is applied to of top science technology, and the manufacturing that is applied to national defense industry from daily life, the place of every use metallic substance all exists etching problem in varying degrees.According to relevant expert's statistics, the whole world each minute half just has one ton of steel to be etched into iron rust.For example, 1975, the financial loss that U.S. every year is caused by corrosion accounted for 4.9% of total value of production in national economy up to 82,000,000,000 dollars; Nineteen ninety-five, the U.S. is because the financial loss straight line that corrosion causes rises to 3,000 hundred million dollars.Statistics shows, in a country that industry is flourishing, the financial loss that causes because of corrosion accounts for 2%～4% of total value of production in national economy, surpasses the summation of the loss that all natural disasteies such as floods, fire, earthquake and ancient measure of length, equal to 8 cun wind cause.Although China only is a developing country, because the loss that corrosion brings is also considerable, annual about 5,000 hundred million yuans, account for about 6% of Chinese national economy total output value.The financial loss that is only caused by corrosion in oil and gas field every year is with regard to about 10,000,000,000 yuan, and coal-mining industry is about 55.6 hundred million yuan by the fund waste that corrosion causes every year, then nearly 1,700,000,000 yuan of the corrosion loss in power system every year.
Therefore, from limited resources and the energy, modern demand of industrial production component of machine has enough wear and corrosion behaviors, can extremely work long hours under the rugged environment at high temperature, high loading etc., and the attrition and attack problem that therefore solves metal is extremely urgent.
Wear-resisting, anti-corrosion, the high temperature resistant and anti-oxidation characteristics of the obdurability that the laser melting coating ceramic technology can be high with metal, good manufacturability and stupalith excellence combines, being the surface strengthening technology of most worthy and competitive power, also is one of focus of laser melting and coating technique development.
Laser melting coating is the technology of emerging a, fast development, it is under the high-energy-density laser beam irradiation, the matrix surface skim melts simultaneously with the alloy that adds as required, forming thickness is 10～1000 μ m surface melting layers, the processing method that rapid solidification requires to satisfy a certain property, be a new technology of the multidisciplinary intersection such as material interaction and rapid solidification moulding in set laser heat fused, the molten bath, this technology obtains more careful research aspect surface treatment.
Because local surfaces is subjected to heat density large, spot diameter is little, and heated time is short, so the melting area is very little on the workpiece surface, passes to the inside workpiece less calories, has very large thermograde in the melting area, and speed of cooling can reach 10
4～10
9℃/s.Just because of rapid solidification, give the characteristics that alloy is different from normal freezing.As the laser melting coating of one of surface modification means, be suitable for top layer modification and the reparation of each metalloid.Cladding laser surfaces can keep former coating alloy composition (thinning ratio 5～8%), and only at the very limited phase diffusion zone of reflow zone and the intersection existence of matrix, and this spreading area realizes that just the metallurgical binding of coat and matrix is necessary.It can be coated in high performance powdered alloy on the common material (workpiece), thereby obtains the top coat (such as good coatings such as heat-resisting, anti-corrosion, wear-resisting, shock resistances) of excellent specific property.
Compare with traditional surface modification (thermospray, plasma spraying etc.) technology, it mainly contains following advantage: the interface is metallurgical binding; Organize superfine; Cladding layer homogeneous chemical composition and extent of dilution are low; Coating thickness is controlled; The heat distortion is little; Realize that easily constituency cladding and technological process easily realize automatization.In process for modifying surface, laser melting coating has become relatively more active research field.
The laser surface coating technology is one of the advanced subject in the material surface engineering field that grows up of middle nineteen seventies, both at home and abroad just flourish.Along with the development and perfection of superpower laser and supporting technology, it progressively moves towards industrial application from laboratory study, will have powerful vitality in following material surface modifying field.Laser melting coating both can be used for the surface modification of traditional material, promoted the performance of material, can be used for again the reparation of surface failure part, so available body material is very extensive, such as carbon steel, steel alloy, cast iron and aluminium alloy, copper alloy, nickel base superalloy etc.In addition, the material scientific research personnel has also developed non-crystalline state and quasi crystal coating etc.At present, more at the study on the modification on traditional material surface to laser technology both at home and abroad, the research of high quality steel, high-temperature alloy surface modification also has report, yet the application laser melting coating is repaired the practical engineering application of some components of machine and is but awaited further popularization, major cause is that the problems such as crackle, coating be inhomogeneous are often arranged in the laser cladding process, awaits the further research of scientific worker.
That the state of laser melting coating layer material generally has is Powdered, thread, paste etc.In addition also can be with sheet metal, sintered metal product, steel band and welding rod etc. as cladding material, wherein powdered alloy is most widely used in laser melting and coating technique.
Practical service environment condition depending on workpiece is different, and is also different to the performance requriements of surface coating.The cladding alloy system mainly contains ferrous alloy, nickel-base alloy, cobalt-base alloy and complex alloy powder etc.It is local wear-resisting and hold yielding part that iron(-)base powder is suitable for requirement; Nickel-base alloy is suitable for that the requirement part is wear-resisting, the member of heat and corrosion resistant and thermal fatigue resistance, and required laser power density is higher than the summary of cladding ferrous alloy; The cobalt-base alloy coating is suitable for the part of wear-resisting, the anti-corrosion and thermal fatigue resistance of requirement; Ceramic coating at high temperature has higher intensity, and Heat stability is good, and chemical stability is high, is applicable to the part of wear-resisting, anti-corrosion, high temperature resistant and oxidation-resistance.
Wear-resistant coating is to study to such an extent that also be maximum a kind the earliest in the laser melting coating ceramic coating.Although Ni is basic, Co is basic, the basic self-fluxing alloy of Fe itself just has good wear-resisting, anti-corrosion, resistance toheat, utilize their laser cladding layer carry out material surface strengthening the research report oneself through a lot.But under the serious condition of slip, gouging abrasion and abrasive wear, simple Ni base, basic, the not competent service requirements of the basic self-melting alloy of Fe of Co.
Matrix material is a kind of novel surface strengthening engineering materials, and metal and metal, metal and pottery, pottery be with ceramic etc., between the powdered alloy and the range of choice of the collocation between powdered alloy and the pottery very extensive.Recent domestic has been carried out various dystectic carbide, nitride, boride and the ceramic oxide particle that adds certain content in the powdered alloy system of above-mentioned laser melting coating for this reason, make cermet composite coating even pure ceramic coating, to improve the wear resistance of cladding layer.
Can prepare high performance composite coating although adopt matrix material to carry out laser melting coating, but at present domesticly mostly still be in the research in laboratory, and its preparation technology adopts the WC powder of nickel-based self-fluxing alloy with certain content mixed in the laboratory, then add saturated turps or homemade organic binder bond, furnishing slip or paste, precoating is overlying on the workpiece, then carries out laser melting coating or sintering.Its hard particles that adds is large, density is different from matrix metal, and the distribution of particle in cladding layer is often inhomogeneous, usually presents Gradient distribution; The wettability of added particulate material and matrix, stability, the coefficient of expansion and chemical reactivity etc. all cause the ununiformity of the microstructure and property of cladding layer.And prepared combination powder since each constituent element proportion differ greatly, thereby in storage, transportation and use procedure and easily produce segregation.Can't carry out the commercialization supply, there is not yet at present particle in market and strengthen the merchandise sales of laser melting coating special powder.For above-mentioned reasons, there is not yet so far laser melting coating special combination powder, thereby restricted the application of laser melting coating on high abrasion operating mode field.
