Tribological Performance of Coated Surfaces Anssi Laukkanen1,Kenneth Holmberg1 (1.VTT Technical Research Centre of Finland, Espoo, Finland) 摘要:The fundamentals of coating tribology is presented in a generalised holistic approach to friction and wear mechanisms of coated surfaces in dry sliding contacts. It is based on a classification of the tribological contact process into macromechanical......

to increase the wear resistance. The phase and microstructure of the coatings were analyzed by X-ray diffractometry and transmission electron microscopy. The wear properties of the coatings were also investigated by means of sliding wear test. The results show that the coating consists of amorphous phase in majority and nanocrystalline phase in minority. The amorphous coatings can be obtained while......

The wear mechanisms of the composites under the two different sliding conditions were also comparatively discussed, based on scanning electron microscopic examination of the worn composite......
mechanism was also discussed. The results show that TC4 alloy has a poor wear resistance, but two particles significantly change its wear performance. As the continuous solid particle layers of MoS2...质量损失随载荷增加而急剧增加.当添加MoS2时,质量损失在10~20 g范围内,增加极为缓慢,但当载荷超过20 N后磨损质量损失快速增加.尽管如此,其磨损质量损失在整个测试范围内仍然小于未添加颗粒时的.当添加Fe2O3时,TC4合金的磨损质量损失几乎为零,且随着载荷的增加产生略微的波动. 图3 添加不同颗粒时TC合金的磨损质量损失曲线 Fig. 3 Wear loss......
fretting resistance of steel. For example, YE et al [15] investigated the tribological performance of MoS2 coating in fretting condition. The results indicated that the friction and wear performance... that the formation of wear debris is closely related to lubricating performance of MoS2 coatings. When the MoS2 coating is broken through, oxidation takes place on the worn surface, which leads......
