AlCrN/硅系陶瓷在大气、海水环境下的摩擦学性能
Tribological performance of AlCrN coating sliding against Si-based ceramic balls in ambient air and seawater conditions
摘要
Abstract
AlCrN coatings were deposited on 316L stainless steel substrates by the multi-arc plating technique. Composition, morphology, phase and hardness of the AlCrN coatings were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and nano-indenter tester. The tribological performance of AlCrN coatings sliding against the Si3N4 and SiC ceramic balls under ambient air and seawater conditions were investigated by using a tribometer (Rtec). The results show that the coefficient of friction and wear rates of AlCrN/SiC are far lower than that of AlCrN/Si3N4 in both environments. The tribochemical product (SiO2) occurs on the wear area and being acted as a lubricant. Dimples on the surface of SiC are in favor of keeping the tribological film in the wear track and relieving the abrasive wear. In comparison with Si3N4, the AlCrN coating sliding against SiC ceramic exhibits more excellent tribological properties.关键词
