AISI 52100 钢经过等离子渗氮处理，与热淬火和未处理的样品相比，在烷基萘润滑条件下与 AISI 52100 钢滑动时表现出显着的摩擦稳定性。在润滑油添加剂ZnDDP和PN（烷氧基磷酸胺盐）存在下，该体系在300N的不同频率下表现出优异的摩擦稳态和0.10至0.11之间的低摩擦系数。通过X射线衍射（XRD）检查渗氮层的相组成，并通过扫描电子显微镜和X射线光电子能谱分析磨损表面。这表明稳定性主要归因于渗氮钢表面微观结构和相组成的变化以及润滑添加剂与滑动副之间的摩擦化学反应。
AISI 52100 steel was treated by means of plasma nitriding and exhibited remarkable friction stabilization when sliding against AISI 52100 steel under lubrication conditions with alkyl naphthalene, compared with heat quenched and untreated samples. In the presence of lubricant additives, ZnDDP and PN (amine salt of alkoxyl phosphate), the system displayed excellent friction steady-state and low friction coefficient between 0.10 and 0.11 at different frequencies at 300N. The phase composition of the nitrided layer was examined by X-ray diffraction (XRD) and the worn surfaces were analyzed by scanning electron microscope and X-ray photoelectron spectroscopy. It indicated that the stability was mostly attributed to the change in the microstructure and phase composition of the nitrided steel surfaces and tribochemical reactions between lubrication additives and sliding pairs.
