Abstract

The invention discloses a wear resistant zinc alloy material and a preparation method thereof. The material uses zinc alloy as a base body in which a metal wire cluster formed by copper wires and iron wires is distributed, the diameters of the copper wire and the iron wire both range from 1to 2 mm, the diameter of the metal wire cluster ranges from 10 to 15 cm, the lengths of the copper wire and the iron wire in the material are equal, and the sum volume of the two metal wires is 10-35% (v / v) of the material. The wear resistant zinc alloy material has high wear resistance, low production cost and simple process.

Description

technical field [0001] The invention belongs to the field of metal materials, and relates to a wear-resistant zinc alloy material and a preparation method thereof. Background technique [0002] In the field of metal materials, wear-resistant zinc alloys have been widely valued as wear-resistant materials. [0003] CN98110581.5 discloses a wear-resistant alloy material, a cast wear-resistant zinc-aluminum alloy. The material is based on zinc, with aluminum and copper as the main alloying elements. By adding antimony, magnesium, titanium, boron and lanthanum elements, it is subjected to micro-multiple alloying treatment, grain refinement and modification treatment, and melt heat treatment smelting process is adopted. The ideal bearing alloy structure with hard spots distributed on the soft matrix with fine grains is obtained, which improves the mechanical properties of the alloy, improves its friction and wear characteristics and casting quality. However, the process is rel...
