In this paper, low temperature solid powder chromizing(LTSPC) technology was exploratory researched, Cr-diffusion layers were get on annealed and quenched 20&45 steel. Then the layers'morphology, component, phases, formation mechanism were discussed.
Through the research, it's proved that the chromizing layers could form on annealed and quenched 20&45 steel at 580-650℃for 3-5h, with the help of chromizing agent, the layer is about 2-8μm. The layers'quality was related by carbon content, pre treatment, h...
