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 wear resistance

especially under high loads

as a result of friction heat changing the coating to a perfect adhesive tribology surface. Micro-hardness of the coating reaches 500Hv

which makes the coating exhibit a lower wear rate

belonging to the mild wear.
