Abstract

The invention discloses a damping abrasion resistant magnesium alloy material and a preparation method thereof. The material uses a magnesium alloy as a matrix, and a steel wire roll and carbon fiber are distributed in the matrix; the diameter of the steel wire roll is 10-15cm, the section of the used steel wire is rectangular, and the section of the steel wire has the specification of 0.1-0.4mm*0.5-1.5mm; and the weight ratio of the steel wire to the carbon fiber is (25-30):1, and the steel wire and the carbon fiber account for 20-40 percent by volume of the material. The magnesium alloy material prepared by the invention has the advantages of higher toughness and abrasion resistance, simple process and low production cost.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a steel wire and carbon fiber composite reinforced damping wear-resistant magnesium alloy material and a preparation method thereof. Background technique [0002] In the field of metal materials, damping and wear-resistant magnesium alloys have been widely valued as wear-resistant materials. [0003] Quan Jun and other foundry technology studied the magnesium alloy microstructure and properties of magnesium alloy AZ31 in the 9th issue of 2010. Zhao Xu and other materials engineering journals published a study on the wear properties of magnesium alloy AZ31 in the fifth issue of 2008. As-cast magnesium alloy AZ31 consists of matrix phase α-Mg and second phase Mg 17 A1 12 Composition, the content of the second phase is less, and it is distributed in the matrix in granular form. The wear mass loss of the specimen increases linearly with the increase of wear time under d...
