Abstract

The invention discloses a damping wear-resistant aluminum alloy material and a preparation method thereof. In the damping wear-resistant aluminum alloy material, aluminum alloy serves as a matrix; steel wire rolls and carbon fibers are distributed in the matrix; the diameter of each steel wire roll is 10 to 15 centimeters; each steel wire has a rectangular section and the section size is 0.1-0.4 mm*0.5-1.5 mm; the weight ratio of the steel wires to the carbon fibers is 25-30:1; and the steel wires and the carbon fibers account for 20 to 40 percent of the volume of the material. The damping wear-resistant aluminum alloy material prepared by the method has high toughness, wear resistance, a simple process and low production cost.

Description

Technical field [0001] The invention is a metal material field, which involves a composite steel wire and carbon fiber composite enhanced damping wear -resistant aluminum alloy material and its preparation methods. Background technique [0002] In the field of metal materials, wearing abrasion -resistant aluminum alloys have been widely valued as wear -resistant materials. [0003] CN200610165341.x Application has disclosed a high -strength damping abrasion -resistant aluminum alloy and its preparation method.The TIC particles are generated in the AL -Zn -MG -CU alloy melt through the original reaction, and then the atomization is formed. Among them, the TIC entry volume of the TI -C -Al prefabricated block is Al -Zn -3.15 to 10.5 % (weight %) of MG -CU alloy.The preparation method is: (1) Press TI powder, graphite powder and aluminum powder to suppress Ti -C -Al prefabricated block for later use; (2) melting Al -Zn -MG -CU alloy;-L -Zn -Mg -CU alloy melt is placed in situ in sit...
