Problems solved by technology

[0003] Existing aluminum alloy materials have good toughness and anti-corrosion properties. However, the surface hardness of aluminum alloy materials is average. For some long-term wear environments, the wear resistance of aluminum alloy materials is insufficient, which will cause damage to aluminum alloy materials. Rapid wear, resulting in damage, for this reason, we propose a high wear-resistant aluminum alloy material treatment process to solve the above problems

Abstract

The invention discloses a high-wear-resistance aluminum alloy material treatment process which comprises the following operation steps that a pure aluminum block is added into a boiler for melting, and subjected to impurity removing and deoxidizing; an aluminum alloy material is put into a refining furnace for refining; alloy is added for modulation treatment, and an aluminum alloy melt X is obtained; the aluminum alloy melt X is subjected to argon shield die casting at the temperature of 600 DEG C, and finally subjected to air cooling to the room temperature; and the aluminum alloy melt X iscast through a semi-continuous casting method, water cooling is conducted after casting, and an aluminum alloy casting body Y is obtained. Through the heat treatment process, the cracking risk of thecasting can be greatly reduced on the premise that the mechanical property of the aluminum alloy casting is improved, and the quenching quality of parts is improved, so that the structural hardness ofthe aluminum alloy material can be greatly improved, and the wear resistance of the material is further improved. According to the high-wear-resistance aluminum alloy material treatment process, an aluminum alloy cylinder body is subjected to surface treatment through electrochemistry, and the surface hardness of the aluminum alloy after surface treatment is high.
