| 摘 要： | 针对高铝青铜粉体材料的涂覆应用,采用HVOF技术制备铝青铜(Cu-14Al-X)粉体材料涂层,并与304不锈钢进行滑动干摩擦试验,结合扫描电子显微镜、能谱和电子探针等手段研究涂层的摩擦磨损性能.结果表明,在滑动干摩擦条件下,HVOF高铝青铜涂层的主要磨损形式是粘着磨损及轻微的磨粒磨损.摩擦热使涂层达到了理想粘着摩擦表面的要求,因此涂层具有十分优良的减摩性能,尤其是在高载荷条件下.HVOF高铝青铜涂层的硬度(HV)为500,该硬度保证了涂层具有较低的磨损率,属于轻微磨损.

| Abstract: | Cu-14Al-X powder coating was prepared by HVOF. Dry sliding experiment against 304 stainless steel was carried out to evaluate the friction and wear behavior of Cu-14Al-X coating by SEM (scanning electron microscope), EDS (energy dispersive spectrometer), EPMA (electronic probe micro-area analysis). The results reveal that under dry sliding conditions, main wear mechanism of Cu-14Al-X coating is characterized by adhesive wear with slightly abrasive wear. The coating possesses excellent self-lubrication and w... |
