摘　　要：用自行研制的保温式多功能离子热处理炉对 45中碳结构钢进行了离子软氮化与离子氧化复合处理 (Ion(NC +O)复合处理 )。Ion(NC +O)复合渗层是由黑色致密的Fe3O4膜、ε白亮化合物层和γ′扩散层等三部分组成。实验结果显示 ,经Ion(NC +O)双重复合处理后 ,45钢的表面硬度和耐蚀性能都有大幅度的提高。与化学法的QPQ技术相比 ,Ion(NC +O)复合处理技术是一种环境友好的处理技术。The surface treatments using plasma nitrocarburizing combined with post oxidation (Ion(NC+O) compound treatments) have been carried out in a self-made heat-preservation multifunction plasma furnace. The complex layer of the treated AISI 1045 steel consists of Fe 3 O 4 film, ε compound layer and γ′diffusion layer. The experimental results show that the surface of the treated steel has a significant improvement in hardness and corrosion resistance. The process of Ion(NC+O) treatment is a kind of environment-friendly process.
