主 题:Cr-Mo coating laser melting microstructure corrosion resistance pitting
摘 要:The precipitation of χ-phase,σ-phase and carbides may be restrained or eliminated by laser melting the plasma sprayed Cr-Mo alloy coating,in which austenite of abundant block usual- ly occurred on medium carbon low alloying *** corrosion resistance of this coating to 0.5mol/L H_2SO_4 was examined to be superior to that of 18-8 stainless *** laser al- loying Cr-Mo coating also has excellent resistance to pitting corrosion,and no pitting ap- peared even it immersed in a medium containing Cl^- ions.
