Abstract

The tribological properties for pulsed W+C and Mo+C dual implanted H13 steel are given in this paper. The pulsed ion of W, Mo and C were implanted at 40KV to dose of (3~12)×1017/cm2 with ion flux from 25 to 100µA/cm2 using MEVVA implanter. The results show that the wear resistance life and hardness of the dual implanted H13 steel increase 2~3 times. The comparison of dual implantation with single implantation shows that the dual implantation is better. The tribological properties of W+C dual implanted H13 steel is better than Mo+C dual implanted H13 steel. The TEM and X-ray diffraction analysis show that the super high hardening dispersed phases of MoC, MoCx, WC and W2C were formed during ion implanting. The iron compounds of tungsten and molybdenum and iron carbides were obtained also. That is, the strengthening effect in H13 steel of phases MoC and WC is better than FeMo, Fe3Mo2, Fe2W and Fe7W6.
