【Abstract】 Effect of the NH₄Cl and sponge-like Ti compound catalyst on nitrocarburizing of 3Cr2W8V steel was investigated,and its acting mechanism was discussed.The results show that the compound catalyst can reduce the nitrocarburizing processes,increase the depth of nitrided layer and enhance the surface hardness.Application of this compound catalyst in nitrocarburizing can improve the quality of nitrided layer remarkably.更多还原
