Background technology
The thermospray aluminum oxide coating layer has good machinery and electric property, as resistance to wear, corrosion-resistant and high temperature thermal insulation coating, obtained widespread use in fields such as machinery, chemical industry, metallurgy.Utilize nanostructure to improve the direction that coating performance has become alumina ceramic coating research; Nanostructure aluminum oxide coating layer with hot-spraying techniques preparation is compared with conventional coatings, all is significantly increased at aspects such as intensity, toughness, anticorrosive, wear-resisting, thermal fatigue resistances.Since the 90's of last century, the hot-spraying nano aluminum oxide coating layer has been obtained fast development.But nano oxidized aluminum coating still exists some problems at coating structure and aspect of performance: the sintering of (1) nano particle problem of growing up.The nanoparticle specific surface area is big; Surfactivity is high, causes fusing point to descend, in the spraying process easily sintering grow up and change proterties; Finally have influence on the maintenance of nanocrystalline structure in the coating, so the nano oxidized aluminum coating of thermospray preparation just has the nanostructure of part usually; (2) coating quality problem.In plasma spraying; Because there is very wide temperature gradient distribution in torch; The melted state of feed particles in torch, temperature distribution, speed of cooling etc. can not be identical; Be difficult to guarantee that all raw materials can both be under the optimized process conditions, thereby be difficult to obtain the coating of even structure, densification.Simultaneously, often density is relatively poor as the agglomerating particles of spraying raw material, and inner pore can left behind in coating, cause the inhomogeneous of coating internal microstructure, and density is poor, finally influences the performance of coating.Usually, the void content of the ceramic coating of plasma spraying is all at 3-5%, even higher.
Summary of the invention
The objective of the invention is,, a kind of aluminium oxide ceramic coating layer with nanocrystal structure and preparation method thereof is provided, thereby further improve the toughness, intensity of coating, mechanical property such as wear-resistant to deficiency of the prior art.
The object of the invention is realized in the following manner.
Nano aluminium oxide ceramic coating with nanocrystal structure of the present invention; Prepare by heat spraying method, include alumina powder in its spraying material component, it is characterized in that; Said spraying material is to be mixed by alumina powder and rare earth oxide to melt the glass particle that forms through cool quickly; Wherein, the weight of aluminum oxide accounts for the 20-75wt% of gross weight, and the weight of rare earth oxide accounts for the 25-80 wt% of gross weight; Said rare earth oxide is any one or the two or more combination in yttrium oxide, lanthanum trioxide, gadolinium sesquioxide, cerium oxide, dysprosium oxide, Neodymium trioxide, the europium sesquioxide.
Preparing method with alumina ceramic coating of nanocrystal structure of the present invention comprises with hot spray process material is sprayed on the matrix, and it is characterized in that, the preparation process is:
(1) preparation mixing fine powders material: take by weighing component aluminum oxide, rare earth oxide, then each component is mixed and added alcohol and carried out wet ball grinding 10-24 hour, oven dry is sieved again, and obtaining granularity is the mixed powder of 20-100 μ m.The weight of said aluminum oxide accounts for the 20-75wt% of gross weight, and the weight of rare earth oxide accounts for the 25-80 wt% of gross weight; Said rare earth oxide is any one or the two or more combination in yttrium oxide, lanthanum trioxide, gadolinium sesquioxide, cerium oxide, dysprosium oxide, Neodymium trioxide, the europium sesquioxide;
(2) preparation glass particle: the mixing fine powders material is directly injected in the normal temperature water purification after through plasma gun or the fusion of oxy-acetylene spray gun; For example zero(ppm) water or deionized water etc.; Sieve after the oven dry again, obtain melting fully, the fine and close granularity of even structure is the alumina base glass particle of 20-100 μ m;
(3) spraying ceramic coat: use air plasma spraying technology or HVAF technology that the alumina base glass particle is sprayed on the matrix, form the ceramic coating with nanostructure, this thickness of ceramic coating is at 50 μ m-2mm.
The present invention prepare earlier fusing fully, the fine and close alumina base glass particle of even structure, then it is formed coating as spraying raw material through heat spraying method, glass particle produces crystallization and separates out nanocrystal heavily melting in the process of cooling.Because the crystal grain that forms is directly separated out from glass matrix; Crystal grain is tiny; Therefore whole coating is the nanostructure that is evenly distributed fully, and adopts the crystal boundary between the nanocrystal that glass presoma nanometer obtains clean, can significantly reduce material intrinsic internal stress.Nanocrystal stops the effect of material micro-crack extension in addition, and this particular structure makes coating have mechanical propertys such as good bonding strength and high abrasion resistance.Compare existing thermospray aluminum oxide coating layer, it has also eliminated the pore that short texture brought owing to the material of reuniting, and simultaneously, because vitreous fusing point is relatively low, it has the viscous mobilization when fusion, and this extremely helps forming fine and close more coating.Through detecting, coating void content of the present invention reaches below 2%.
Alumina ceramic coating with nanocrystal structure of the present invention, component is simple, and raw material is easy to get, and is with low cost; Preparation technology is succinctly easy to operate, is suitable for large-scale production.
Below in conjunction with embodiment technical scheme of the present invention is described further.
