| Abstract: | The paper deals with the results on processing parameters of laser transformation hardening for 35CrMo Rotating Union by using(L 934)orthogonal experiment. The results shows the surface harden by Laser Transformation Hardening is 30 per more than by carburization hardening and the wear-resistance increase one double and especially, most of the residual stress of the interior of the material is changed into compressive stress. The experimental results provide a basis to improve the surface properties of rotating union. |
