摘要
运用QPQ盐浴复合处理技术对H13钢进行表面强化处理,分析了不同工艺参数对氮化层深度、显微硬度和抗腐蚀性的影响及氮化层显微组织特征。结果表明,在相同的渗氮温度下,渗氮层的深度随渗氮时间的延长而增加,氮化后的材料硬度和耐腐蚀性较渗氮前有较大的提高,氮化3～4h效果最好。
The QPQ complex salt-bath treatment process for surfaces strengthening of H13 steel was studied, the effects of technology parameters on the nitriding-layer depth, the hardness and the anti-corrosion performance and the microstructure of the nitriding-layer were analyzed. The results show that the nitriding-layer depthat the same nitriding temperature increases with the time increasing. The H13 steel treated by QPQ salt bath process has higher hardness and anti-corrosion, and the effect will be best at the nitriding time of 3-4h.
