Abstract

The invention provides a high wear-resistant aluminum alloy material and a preparation method thereof. The high wear-resistant aluminum alloy material is composed of the following components by weight percentage: 1.23-2.61% of magnesium, 0.23-0.57% of iron, 0.21-0.36% zinc, 0.42-0.92% manganese, 0.38-0.62% cerium, 0.23-0.40% yttrium, 0.63-0.94% titanium, 0.23-0.41% cobalt, 0.12-0.25% scandium, 5.6- 7.8% silicon, the rest is aluminum and a small amount of unavoidable impurities. In the present invention, the addition of cerium and yttrium in the aluminum alloy material can improve the wear resistance of the aluminum alloy material; the addition of cobalt and scandium can improve the toughness of the aluminum alloy material, overcome casting cracks, improve the quality of the aluminum alloy, and improve the quality of the aluminum alloy. Product cost rate. According to the experimental results, the hardness of aluminum alloy products is above 689HV, the strength is above 542MPa, and the qualified rate of flaw detection is above 99%.

Description

technical field [0001] The invention belongs to the field of aluminum alloy materials, and in particular relates to a high wear resistance aluminum alloy material and a preparation method thereof. Background technique [0002] Aluminum alloy is an alloy composed of aluminum as the matrix element and then adding one or more alloy elements.
