Multi-Layer Metal Matrix Alloy Surfacing Composite Material Fusion Research on the 45Mn-Austenitic Stainless Steel-(Cr-Ni) System ZHAO Yu-ping1, XU Yu-hai2 1ZHAO Yu-ping,，2XU Yu-hai.Ningxia Industry and Commerce Professional Technology College,Ningxia750021,China. 1Email:1048817108@qq.com 2Email: nxjdxyh@163.com Key words: Composite materials, Multi-layer, Fusion, Matrix, Wear resistance Abstract This article in view of the 45Mn-austenitic stainless steel-(Cr-Ni) system composed of metal alloy surfacing multilayer composite materials of the fusion mechanism research, through the hardness testing, impact test and analysis of the abrasion resistance testing, the results show that: Cr-Ni surfacing welding metal alloy system has good abrasion resistance, but the fusion welding the gender is poorer, as long as the matrix in martensite properly morphology of carbon dioxide, its hardness &abrasion resistance may achieve in, high carbon equivalent to achieve performance, show that
Wear test start before, first in one over ten thousand of the analysis on the Ping day take the quality of says, is easy to wear after 12h, taking samples, the water to rinse clean with acetone after drying take samples of the weight of the said again, can be used to calculate the wear rate.
