| 摘 要： | 氧化铝陶瓷涂层因具有良好的耐磨、耐蚀性能而得到广泛的应用.本文利用销-盘式摩擦磨损试验机研究了大气等离子喷涂Al2O3涂层与GCr15摩擦副的室温干滑动摩擦磨损特性,用扫描电镜和能谱仪对磨损区域进行了分析.结果表明:在室温干摩擦条件下,Al2O3陶瓷涂层的磨损量随载荷的增加而增加,当载荷大于50 N时,涂层的磨损量随载荷的增加而降低,随线速度的提高而增加.在摩擦过程中,陶瓷涂层表面产生的表面膜,使涂层的磨损量减小.Al2O3涂层的磨损机理是脆性微剥落和粘着磨损共同作用.

| Abstract: | Alumina coating has been widely used due to its good wear and corrosion resistance.The characteristics of dry wear behavior for air plasma spray alumina coating against GCr15 steel was investigated using pin-tray tribometer at the ambient temperature in this paper,and the worn scars were examined by scanning electron microscope and energy dispersive spectroscopy.The experimental results indicated that the mass loss of alumina coating was increased with the rise of load while the mass loss of coating was dec... |
