Problems solved by technology

[0004] Aluminum-silicon alloy is a common aluminum alloy. Changes in the ratio of aluminum to silicon can have a great impact on hardness. For example, when the silicon content is less than 7%, the aluminum-silicon alloy has good ductility, and the silicon content exceeds the aluminum-silicon eutectic. After the point, the hardness and wear resistance of the alloy are significantly improved, but although the existing aluminum-silicon alloy has relatively high wear resistance and hardness, due to the complex operation and difficult control of the processing quality in the production method, and its low corrosion resistance

Abstract

The invention relates to the field of special metals, and in particular to a wear-resistant aluminium-silicon alloy. The wear-resistant aluminium-silicon alloy disclosed by the invention comprises the following components in percentage by mass: 30-50% of aluminium, 10-15% of silicon, 5-10% of magnesium, 1-3% of chromium and 1-5% of manganese. The wear-resistant aluminium-silicon alloy provided by the invention has the beneficial effects that the hardness is increased, and the corrosion resistance is remarkably improved.

Description

[0001] technical field [0002] The invention relates to the field of special metals, in particular to a wear-resistant aluminum-silicon alloy. [0003] Background technique [0004] Aluminum-silicon alloy is a common aluminum alloy. Changes in the ratio of aluminum to silicon can have a great impact on hardness. For example, when the silicon content is less than 7%, the aluminum-silicon alloy has good ductility, and the silicon content exceeds the aluminum-silicon eutectic. After the point, the hardness and wear resistance of the alloy are significantly improved. However, although the existing aluminum-silicon alloy has relatively high wear resistance and hardness, the production method is complex in operation, difficult to control the quality of treatment, and its corrosion resistance is low. [0005] Contents of the invention [0006] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a wear-re...
