Description
Technical field
The invention belongs to field of aluminum alloys, and in particular to a kind of antiwear heat resisting aluminium alloy.
Background technology
Alusil alloy is a kind of common aluminium alloy, and the change of alumina silica ratio can make hardness produce very big influence, such as silicone content
When less than 7%, alusil alloy has good ductility, and after silicone content exceedes al-si eutectic point (11.7% silicon), alloy
Middle silicon grain substantially increases, and the hardness and wearability of alloy also significantly increase, and existing method carries out electrification by alusil alloy
Learn treatment and the silicon in matrix is retained with etch top layer aluminium, its wearability and hardness are improved to carry out a step, but the method is present
Complex operation, the treatment uppity problem of quality, the research simultaneously for the high temperature fatigue strength of aluminium alloy is also people's research
Emphasis, have at present it is many with good heat resistance can aluminium alloys, but the aluminium alloy with antiwear heat resisting performance is more rare.
The content of the invention
In order to solve the above problems, the invention provides a kind of aluminium alloy of antiwear heat resisting.
Technical scheme is as follows:
A kind of antiwear heat resisting aluminium alloy, the alloy constitutes and is by weight：Silicon 5-12%, magnesium 3-8%, iron 0.8-1.2%, titanium
2-5%, manganese 0.1-0.5%, strontium 0.8-1.5%, ytterbium 0.01-0.05%, tungsten 0.5-0.8%, copper 0.5-0.8%, aluminium 3-5%,
Cerium 0.2-0.3%, zinc 0.5-1.8%, chromium 0.8-1.5%.
Further, above-mentioned antiwear heat resisting aluminium alloy, the preparation method of aluminium alloy is：Described all elements are existed in proportion
Melting at 700-900 DEG C, pours shaping at 800-850 DEG C.
Beneficial effects of the present invention：
Compared with prior art, the aluminium alloy that the present invention is provided, using composition of the invention, can significantly improve the resistance to of aluminium alloy
Mill degree and temperature capability, its hardness have reached 600 or so.
