本文简单介绍了国内外对耐磨合金堆焊工艺的研究,阐述了组成合金浸润堆焊新工艺及其材料的研究和试验过程。研究表明:以不同粒级配比的铸造碳化钨为耐磨相,以Cu—Mn—Ni—Si合金为浸润合金,采用特制型腔和特殊保护进行炉中浸润堆焊。对磨损工件和模具是一种良好的堆焊方法,其堆焊层的硬度达HRc=92～94,耐磨性大大提高。 This article briefly introduces the domestic and international research on the wear-resistant alloy surfacing technology, elaborates the research and test process of the new alloy surfacing welding technology and its materials. The results show that cast tungsten carbide with different grain size is wear-resistant phase, Cu-Mn-Ni-Si alloy is wetting alloy, and special-type cavity and special protection are adopted for wetting in the furnace. On the wear of the workpiece and the mold is a good method of surfacing, the surfacing layer hardness HRc = 92 ~ 94, greatly increased wear resistance.
