| Abstract: | Through analyzing the subzero and cryogenic treatment process of 18Cr2Ni4WA and 20Cr2Ni4A steel, the reasonable process parameters were determined by test and applied to the actual production of carburized gear parts. The results show that the subzero and cryogenic treatments can improve the hardness of the carburized gears of 3-5 HRC, and can effectively increase the depth of hardened layer. |
