Abstract
A self-shielded flux with Fe,Cr,Ni and so on was welded onto 45 steel substrate and prepared to iron-based surfacing welding coating.The macro-morphology and welding process conditions were assessed.The phase composition and microstructureof the surfacing coating were characterized.And it's hardness,wear resistance,corrosion resistance,thermal stability,crack resistance,self-protective properties,etc were studied.The results show that welding coating contains amorphous,with good wear-resistant,crack resistance,corrosion resistance,and good thermal stability,welding process performance,excellent comprehensive properties.关键词
