| 摘 要： | 本文研究了SDC99钢TD法盐浴渗钒在不同温度,不同时间下的覆层厚度,建立了覆层生长动力学模型,并以Cr12MoV和T10钢作为对比试样,表明基体中的固溶碳含量控制覆层厚度及生长速率.覆层的力学性能测试结果显示,经TD渗钒后材料表层的硬度超过24 GPa,较渗钒前提高了约4倍,且耐磨损性能得到大幅度提高.

| 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. |
