Abstract
The aluminum alloy cylinder sleeve is made of high-silicon aluminum alloy. The cylinder sleeve made of the high-silicon aluminum alloy has the characteristics of good castability, good wear resistance and small linear expansion coefficient, and compared with the cylinder sleeve made of cast iron, the cylinder sleeve made of the high-silicon aluminum alloy reduces the weight of an engine or a compressor and reduces the oil consumption of an automobile. The insert casting process of the aluminum alloy cylinder sleeve comprises the following steps: 1) activating the surface of the aluminum alloy cylinder sleeve, which is in contact with the cylinder matrix; 2) and carrying out grain boundary bonding on the treated aluminum alloy cylinder sleeve and the cylinder matrix. When the high-silicon aluminum cylinder sleeve is used for inlaying casting, the surface of the cylinder sleeve is subjected to activation treatment, so that the combination of the cylinder sleeve and the cylinder matrix is combined by the original mechanical combination to achieve crystal boundary combination, and the combination strength of the cylinder sleeve and the cylinder matrix is greatly improved.
Description
Technical field
The present invention designs a kind of aluminium alloy cylinder sleeve, and especially a kind of high-silicon aluminum alloy cylinder sleeve the invention still further relates to the imbedding process of above-mentioned cylinder sleeve.
Background technology
Cylinder sleeve is the liner (cylinder liner) of cylinder, has only very thin one deck, adopts spheroidal graphite cast iron (or claiming ductile cast iron, ductile iron) to make usually, is responsible for directly contacting with piston ring, and behind the cylinder body casting, processing is pressed in it.
Because cylinder wall bears the stress that the transverse thrust of high pressure gas and piston causes, and because the thermal stresses that high-temperature gas causes, cylinder jacket material must have higher structural strength and fatigue strength, destroys to avoid cylinder-liner distortion or material premature fatigue.In addition, cylinder sleeve also must have good wear resistance and bite-resistant performance.The cylinder sleeve great majority adopt graphitic cast iron or austenitic iron to make.For the mechanical strength that improves cylinder sleeve with improve wear resistance, need to add elements such as nickel, chromium, copper and molybdenum, formed heterogeneous metal.
Because aluminium lighter weight, add that aluminium alloy has certain intensity and wear resistance, therefore, on light duty engines such as automobile, motorcycle, aluminium alloy cylinder sleeve has certain usage space, but, must improve the pressure-bearing limit and the sturdy and durable degree of cylinder jacket material along with the lifting that the maximum of modern light diesel engine is born pressure.
Aspect the shaping of cylinder sleeve, the main method of utilizing casting.Wearing and tearing in the cylinder mainly contain cutting abrasion, adhesion wear, abrasive wear, four kinds of forms of corrosive wear, therefore, carry out surface treatment to cylinder sleeve, improve its hardness, wear resistance, to prolong its life-span.Traditional surface treatment method is to carry out carburizing, nitriding or carbonitriding, develops into electroplating technology, Laser Surface Treatment, plasma treatment etc. afterwards.Above-mentioned treatment process respectively has advantage.
Summary of the invention
The object of the present invention is to provide the aluminium alloy cylinder sleeve that a kind of castibility is good, wear resistance is high, linear expansivity is little; Another object of the present invention is to provide the conjugation very high imbedding process of a kind of of above-mentioned aluminium alloy cylinder sleeve with the cylinder matrix.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of aluminium alloy cylinder sleeve, it adopts silumin to make.
A kind of imbedding process of above-mentioned aluminium alloy cylinder sleeve comprises the steps: 1) activation treatment is carried out on the surface that contacts with the cylinder matrix of described aluminium alloy cylinder sleeve; 2) treated described aluminium alloy cylinder sleeve carries out crystal boundary with described cylinder matrix and combines.
Because the employing of technique scheme, the present invention compared with prior art has the following advantages:
Adopting silumin is that cylinder sleeve has the characteristic that castibility is good, wear resistance is good, linear expansivity is little, adopts this type of cylinder sleeve, compares with adopting Cast iron liner, has alleviated the weight of engine or compressor and has reduced automobile fuel consumption.When using high silicon-aluminum cylinder sleeve castingin,, make cylinder sleeve reach the crystal boundary combination, cylinder sleeve and cylinder high base strength are improved greatly with combining of cylinder matrix by original mechanical bond by activation treatment is carried out on the cylinder sleeve surface.
Embodiment
A kind of aluminium alloy cylinder sleeve adopts silumin to make.The silicone content of silumin is 16～24%.Silumin go bad and thinning processing after, crystallization and freezing becomes cylinder sleeve under pressure.Adopting silumin is that cylinder sleeve has the characteristic that castibility is good, wear resistance is good, linear expansivity is little, adopts this type of cylinder sleeve, compares with adopting Cast iron liner, has alleviated the weight of engine or compressor and has reduced automobile fuel consumption.
A kind of imbedding process of above-mentioned aluminium alloy cylinder sleeve comprises the steps: 1) activation treatment is carried out on the surface that contacts with the cylinder matrix of aluminium alloy cylinder sleeve; 2) treated aluminium alloy cylinder sleeve carries out crystal boundary with the cylinder matrix and combines.When using high silicon-aluminum cylinder sleeve castingin,, make cylinder sleeve reach the crystal boundary combination, cylinder sleeve and cylinder high base strength are improved greatly with combining of cylinder matrix by original mechanical bond by activation treatment is carried out on the cylinder sleeve surface.
