Ferrous alloy powder for laser cladding

Abstract

This investigation aimed at how to improve the hardness and wear resistance by B, Si and Cr, and how to improve the synthesis property by Re (rare-earth element). Based on the experiment of Fe-based alloys of Fe−Cr−Ni−B−Si−Re, through experiments and a serious of synthesis analysis, including surface quality, spectrum composite, micro-hardness, scanning electron microscopy, as well as the synthesis evaluation, etc, prescriptions were optimized. As a result, a Fe−Cr−Ni−B−Si−Re cladding material with a high property was obtained.
