| 摘 要： | 银基涂层作为一种减磨润滑涂层,具有良好的润滑性。本文采用大气等离子热喷涂方法在不锈钢基体上制备了银基涂层,并采用扫描电镜、灰度法、拉伸法、摩擦磨损等方法对涂层的微观结构、孔隙率、结合强度、硬度、摩擦系数、磨损量、耐蚀性能进行了研究。试验表明,在适当的喷涂工艺下制备的银基涂层组织致密,孔隙率低至0.55%,结合强度达50MPa以上,摩擦系数低至0.1683,耐腐蚀性能优异。

| Abstract: | As a kind of antifriction lubrication coating, silver based coating has good lubrication. The silver
based coating is prepared on the stainless steel substrate by atmospheric plasma thermal spraying. This paper studies on the microstructure, porosity rate, bonding strength, hardness,wear resistance and corrosion resistance of the coating. The test shows that the microstructure of the silver based coating prepared under the suitable spraying process is compact. The porosity rate is as low as 0.55%, the bonding strength is above 50MPa,the coefficient of friction is as low as 0.1683, the corrosion resistance is excellent. |
