中文摘要:
      目的 研究磨料水射流-离子渗氮复合处理对316不锈钢摩擦学性能的影响。方法 采用磨料水射流、离子氮化技术分别在316不锈钢表面进行喷丸(WJ-316SS)、渗氮(PN-316SS)、喷丸+渗氮(WJ-PN-316SS)表面强化处理,并采用扫描电镜(SEM)、X射线衍射仪(XRD)、洛氏硬度计、粗糙度测试仪、超景深显微镜、划痕仪和摩擦磨损仪等研究复合处理试样的表面形貌、表层相结构与韧性,并讨论了不同表面处理试样的力学性能以及在干摩擦条件下的摩擦学行为。结果 复合处理后的试样表面形成了连续密排的凹槽织构,表面改性层含有Fe2N、Cr2N、CrN等化合物,离子渗氮层厚度大约为10 μm,表面显微硬度(79HRC)和表面粗糙度(1.10 μm)高于单一表面处理试样。在与Si3N4摩擦配副进行干摩擦的实验中,316SS、WJ-316SS、PN-316SS的摩擦因数分别为0.8、0.4、0.5,磨损质量分别为7.1、3.3、3.7 mg。而WJ-PN-316SS的摩擦因数在0.25附近波动,磨损质量为0.3 mg,明显低于单一表面处理试样,耐磨性能更加优异,其磨损机理主要为疲劳磨损和氧化磨损。结论 磨料水射流-离子渗氮复合处理能显著改善316不锈钢的摩擦学性能。
英文摘要:
      The work aims to study the effect of duplex treatment of abrasive water jet and plasma nitriding on the friction property of 316 stainless steel. Shot peening (WJ-316SS), plasma nitriding (PN-316SS), shot peenning+nitriding (WJ-PN-316SS) were used to strengthen the surface of 316 stainless steel by abrasive water jet and plasma nitriding. The surface morphology, surface layer phase structure and toughness of duplex treated sample were studied, by scanning electron microscope (SEM), X-ray diffractometer (XRD), rockwell hardness tester, roughometer, ultra depth of field microscope, scratch tester and friction wear tester and the mechanical properties and tribological behavior of samples with surfaces treated by different methods were investigated under dry friction condition. After duplex treatment, the continuous compact groove texture was formed on the sample surface and the modified layers consisted of Fe2N, Cr2N, CrN and other compounds. The thickness of the nitriding layer was about 10 μm and the surface microhardness (79HRC) and roughness (1.10 μm) of duplex treated sample were higher than those with surfaces through single treatment. In the experiment, the tribological performance of samples was investigated under dry friction condition against Si3N4 ceramic balls. The friction coefficient of 316SS, WJ-316SS and PN-316SS was 0.8, 0.4 and 0.5, and the mass losses were 7.1, 3.3 and 3.7 mg. However, the friction coefficient of WJ-PN-316SS fluctuated around 0.25 and the mass losses were 0.3 mg, significantly lower than that of samples with surfaces through single treatment, so the wear resistance was more excellent. The wear mechanism was mainly composed of fatigue wear and oxidation wear. The tribological properties of 316 stainless steel can be significantly improved by duplex treatment of abrasive water jet and plasma nitriding.
