| Abstract: |
| A growth dynamic model of vanadium carbide coating on SDC99 steel was established, which was based on the different coating thickness on the SDC99 steel using TD salt-bath vanadizing with different immersion temperatures and time. By comparing with Cr12MoV and T10 steel, the results showed that the thickness and growth rate of vanadium carbide coating are dominated by the dissolved carbon content of substrate. The results of mechanical properties testing showed that the hardness of the surface layer of SDC99 steel was more than 24 GPa after TD Vanadizing,it is about four times higher than that of the matrix. Furthermore, the friction and wear properties can be improved significantly. |
