离子氮碳氧三元共渗对45钢耐蚀耐磨性能的影响与机理研究
Effect of plasma oxynitrocarburising on corrosion and wear resistance for 45 steel and mechanism analysis
摘要
Abstract
To explore an environmental friendly and efficient surface modification technology,PNCO(Plasma oxynitrocarburising)was developed and compared with QPQ(Quench-polish-quench)tech-nology for 45 steel.The cross-sectional microstructures,phase compositions,wear resistance and cor-rosion 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.Mean-while,nanostructured oxide film with denser compound layer was formed by PNCO treatment.Fur-thermore,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 bet-ter wear resistance and corrosion resistance than those by QPQ treatment.The study provides a feasi-ble research area for environmentally efficient surface modification technology with excellent corrosion and wear resistance.关键词
