基于等离子堆焊技术的矿用截齿的耐磨性能研究
Wear Resistance Research of the Plasma Surfacing-Based Mining Picks
摘要
Abstract
In terms of the current problem, which is the serious effects of the wear of the mining pick heads to the efficiency of coal mining and the cost in the actual working environments, a coating with mixed alloy powders on the surface of picks was prepared by using the plasma surfacing method.In this method, with the transfer plasma arc as the heat source, the mixed metal powder with the wear resistance was melted at the high temperature produced by the compressed plasma arc, and then combined with the matrix to form the alloy coating.Thus, the alloy coating with higher wear resistance was obtained, which can further increase the wear resistance and the working life of the mining picks.By comparing the wear resistance of four different coatings with different matching of alloy powders, it is found, with the increase of TiC content in the alloy powder, the wear resistance of coating is significantly enhanced.关键词
