| Abstract: | By analyzing machining-process,pre-heat treatment process and test results,the factors that influenced distortion of the gear during salt bath nitrocarburizing were found out.By adjusting machining process and pre-heat treatment process,matrix strength of the gear is improved,and residual stress was reduced,then distortion of the gear is controlled. |
