%X Onthebase of 20 # steel, Co base alloy with Ce and without Ce was obtained with laser heatingtechnology. Theresultshowsthat Cehasobviouslyeffecton alloy microstructureespe ciallyimprovethecorrosion resistancein acid by31 % ,oxygenation resistanceby23 % ,in al kalescent liquid by 23 % . Improve fearlessness 30% and improve hardness by 168 HV.Throughcontrast and analysison the Co base microstructure with Ce and without Ce .
