Abstract

A sintering and infiltration method for manufacturing tungsten-chromium-copper composite materials. The tungsten-chromium-copper composite materials are composed of the following components by weight percentage: tungsten 32%-50%, chromium 11%-23%, copper 27%-57% , the sum of the weight of each component is 100%. The method includes the following steps: first mix tungsten powder and chromium powder, granulate, press into a billet, then sinter and infiltrate copper liquid, after homogenization treatment and aging treatment be made of. The manufacturing method and process are easy to control, and the prepared tungsten-chromium-copper composite material has stable structure and performance, high density, low oxygen content, moderate hardness, high electrical conductivity, and excellent electromechanical comprehensive performance.

Description

technical field

[0001] The invention relates to a method for manufacturing tungsten-chromium-copper composite material, in particular to a sintering infiltration method for manufacturing tungsten-chromium-copper composite material. Background technique

[0002] The current method of manufacturing tungsten-chromium-copper composite materials is powder metallurgy. In this method, the reduction temperature of chromium powder is low and the reduction is insufficient, resulting in high oxygen content in the material. The tungsten-chromium-copper composite material manufactured by this method The material has low density and many pores in the material, which affects the hardness and conductivity of the material. Contents of the invention

[0003] In order to solve the shortcomings of low density and high oxygen content of tungsten-chromium-copper composite materials produced by powder metallurgy, the purpose of the present invention is to provide a sintering infiltration method ...
