| Abstract: | Through experiments of boronitriding heat treatment process into samples of 5CrMnMo steel,some new process that can improving the service life of the forging dies of 5CrMnMo steel are provided for commercial manufancture,as compared with that of single boronizing, get the follow results that the cemented layer has such superiority as high_wearing feature,anticorrosion oxidation_resistance at high_temperature.As compared with that isothermal heat treatment,hot forging die with the cemented layer treated by isothermal heat treatment can improve its life more than two times. |
