| 摘 要： | 研究了氧化铝陶瓷在HCl溶液、NaOH溶液和去离子水3种润滑介质下的摩擦磨损性能,获得其在不同滑动速度下的摩擦因数、磨损体积和表面形貌.结果表明:酸性环境抑制了硅和铝的氢氧化物膜的产生,导致在HCl溶液润滑下摩擦副的摩擦因数高,氧化铝陶瓷表面磨损严重;以NaOH溶液为润滑介质时摩擦副的摩擦表面成膜度最高,摩擦因数最低,...

| Abstract: | The friction and wear properties of alumina(Al2O3)ceramics in HCl solution,NaOH solution and deionized water are studied to obtain friction coefficient,wear volume and surface morphology of Al2O3 ceramics under different sliding speeds.The results show that the acid environment inhibits generation of hydroxide films of Si and Al,resulting in high friction coefficient of friction pair lubricated by HCl solution and severe surface wear of Al2O3 ceramics.When NaOH solution is used as lubricating medium,the friction surface of friction pair has the highest film-forming degree and the lowest friction coefficient,but the corrosive environment still has a negative impact on friction pair,resulting in higher surface wear volume and wear degree than the deionized water as lubricating medium.At the same time,among the three speeds selected in the test,when the friction pair moves under sliding speed of 0.08 m/s,the friction coefficient and wear volume reach minimum value,and the lubrication effect is the best. |
