| Abstract: | A compound catalyst composed of ammonium chloride(NH4Cl),sponge titanium,rare earths and solid chromate was used in nitrocarburizing of Cr12,3Cr2W8V,and 35CrMo steels.Hardness,depth,microstructure,and phase structure of the nitrocarburized cases were measured and compared with those developed with pure RE catalyst.The experimental results show that the compound catalyst can appreciably accelerate nitrocarburizing,and is superior the pure RE catalyst in the effectiveness. |
