| Abstract: | This paper deals with the influence of the variours process parameters in the ionitriding and gas nitriding of 40Cr and 38CrMoAlA steel on they nitrided layer properties. The experiment result shows that the ionitriding can decrease brittleness, increase wear-risistance, increase stability in size and decrease deformation. It has been applied Successfully in the parts of 125MW water turbine, such main as valve of speed governor bush and other parts. |
