摘要:
研究选择45钢为原材料,分别采用绿色环保离子氮碳氧三元共渗技术(Plasma oxynitrocarburising, PNCO)和传统淬火-抛光-淬火技术(Quench-polish-quench, QPQ)进行表面改性,并利用SEM,XRD,摩擦磨损试验机,浸泡腐蚀实验对比分析2种方法的改性效果,包括截面显微组织、表面形貌、物相、耐磨性和耐蚀性。结果表明,PNCO处理后,获得了与QPQ处理相同的多层次渗层结构,由表层1～2μm氧化膜及次表层化合物层和有效硬化层构成,且PNCO处理后表面氧化膜成纳米结构,化合物层比QPQ更加致密。同时,PNCO处理后,磨损率和腐蚀失重率分别为1.39 mg/(N·m)和0.39%,耐磨耐蚀性均略优于QPQ,为研究绿色高效高性能表面改性技术提供了可行的研究方向。
Abstract:
To explore an environmental friendly and efficient surface modification technology, PNCO(Plasma oxynitrocarburising)was developed and compared with QPQ(Quench-polish-quench)technology for 45 steel. The cross-sectional microstructures, phase compositions, wear resistance and corrosion resistance were tested and analyzed by X-ray diffraction(XRD), scanning electron microscopy(SEM), wear tester and immersion corrosion test. The results show that after PNCO treatment, the same multi-layer structure was obtained as those by QPQ treatment, composed of 1—2 μm oxide layer on the surface and compound layer on the subsurface and effective hardening layer beneath. Meanwhile, nanostructured oxide film with denser compound layer was formed by PNCO treatment. Furthermore, both wear rate and corrosion weight loss rate are slightly lower than QPQ treatment, with wear rate of 1.39 mg/(N·m)and corrosion weight loss rate of 0.39% by PNCO, thus bringing better wear resistance and corrosion resistance than those by QPQ treatment. The study provides a feasible research area for environmentally efficient surface modification technology with excellent corrosion and wear resistance.
