金属钼层表面渗硫层的表征与减摩耐磨性能研究

Wear Resistance of Sulfuration Layer on Metal Mo Layer

对厚约3μm的金属钼薄膜进行低温离子渗硫处理,得到了单质金属钼与固体润滑剂二硫化钼(MoS2)共存的复合固体润滑渗硫层。利用SEM和EDX分析了复合渗硫层表面、截面及磨损面的形貌及成分分布,用XPS分析了复合渗硫层表面化合价态,用纳米压痕仪测定了复合渗硫层的硬度及弹性模量。摩擦磨损实验表明,该渗硫层是一种非常理想的摩擦表面,具有优异的减摩耐磨抗擦伤性能。离子渗硫技术为原位合成固体润滑剂MoS2提供了一种新方法。

The composite solid lubrication sulfuration layer between metal molybdenum and solid lubricant molybdenum disulfide （MoS2） was obtained after the metal molybdenum layer with 3μm thick was treated by low temperature ion sulfuration, The results of friction and wear show that the composite sulfuration layer is a kind of ideal solid lubrication layer and possess an excellent antifriction and wearresistance. SEM equipped with EDX was adopted to analyze the morphologies and compositions of surface, cross-section and worn scar of the sulfuration layer. The valence states of film su measured by a nano tester, The low temperature ion situ rface sulfu were detected by XPS. The nano-hardness and nano-modulus of the layer were ration technology provides a new technique to prepare the solid lubricant MoS2 in situ.
