A kind of production method of wear-resistant aluminum alloy

Abstract

The invention discloses a wear-resisting aluminum alloy. The wear-resisting aluminum alloy is prepared from, by mass, 3.2%-4.15% of iron, 10.2%-11.2% of zinc, 9.66%-10.15% of copper, 1.25%-1.5% of iridium, 0.44%-0.62% of tungsten, 0.28%-0.35% of erbium, 1.02%-1.22% of ruthenium, 0.33%-0.89% of cobalt and the balance aluminum. The aluminum alloy is prepared through vacuum melting, refining, pressure casting, heat treatment, aging and the like. As all the ingredients and all the contents are reasonably set, it is guaranteed that the aluminum alloy has the enough mechanical performance, and particularly has the mechanical performance suitable for the heavy-load and high-temperature use environment; and meanwhile the technological parameters of pressure casting and the pressure parameters of inert gas during refining are optimally selected, and the mechanical performance of the alloy is improved.

Description

technical field [0001] The invention relates to a production method of a wear-resistant aluminum alloy, which belongs to the field of alloy manufacturing. Background technique [0002] Die-casting is a kind of pressure-casting part. It uses a pressure-casting mechanical die-casting machine with a casting mold installed, and pours metals such as copper, zinc, aluminum or zinc alloy heated into a liquid state into the feed port of the die-casting machine, and passes through the die-casting machine. Die casting, casting copper, zinc, aluminum parts or zinc alloy parts of the shape and size limited by the mold, such parts are usually called die castings. Die-casting parts have different names in different places, such as die-casting parts, pressure castings, die-casting parts, die-casting aluminum, die-casting zinc parts, die-casting copper parts, copper die-casting parts, zinc die-casting parts, aluminum die-casting parts aluminum die-casting parts, aluminum die-casting parts ...

AI Technical Summary

Problems solved by technology

[0003] Existing alloy materials for die casting usually include aluminum, iron, copper, zinc and other components. Due to the different content of each element in the alloy, the spatial distribution of each element in the alloy is quite different, resulting in different comprehensive properties of each alloy, especially the mechanical properties. big difference

The casting process is prone to defects such as porosity and segregation, and its service temperature is also low. Often due to the large amount of heat generated by friction and wear under heavy load conditions, the temperature of the parts is overheated and it is difficult to use
