与干摩时相比,三种醇的水溶液都降低了(Ca,Mg)-Sialon陶瓷/GCr15的摩擦系数,但都不同程度地增加了陶瓷的磨损体积.所有醇都降低了(Ca,Mg)-AISialon陶瓷/GCr15的摩擦系数及(Ca,Mg)-Sialon陶瓷的磨损体积;在乙二醇润滑下(Ca,Mg)-Sialon陶瓷/GCr15表现出最低的摩擦系数(0.06);(Ca,Mg)-Sialon陶瓷在四种醇润滑下,磨损体积由大到小的顺序为:乙二醇,1.4-丁二醇,1.3-丁二醇,丙三醇.醇的碳链越长,羟基数目越多,陶瓷的磨损体积越小.所有润滑剂都使得陶瓷磨损表面变得异常光滑,其中醇的效果更明显在醇与陶瓷表面之间发生了摩擦化学反应,在陶瓷表面形成的减摩抗磨膜降低了摩擦系数和磨损体积.
All three alcohol aqueous solutions reduced the friction coefficient of (Ca, Mg) -Sialon ceramic / GCr15 compared with that of dry friction, but both increased the wear volume of ceramic to some extent. All alcohols reduced the friction coefficient of (Ca, Mg) -AISialon ceramic / GCr15 and the wear volume of (Ca, Mg) -Sialon ceramics; the (Ca, Mg) -Sialon ceramics / GCr15 showed the lowest (0.06); (Ca, Mg) -Sialon ceramics in the four alcohol lubrication, wear volume descending order: ethylene glycol, 1.4-butanediol, 1.3- Butanediol, glycerol.The longer the carbon chain of the alcohol, the more the number of hydroxyl groups, the smaller the wear volume of the ceramic. All lubricants make the surface of ceramic wear become very smooth, in which the effect of alcohol is more obvious between the alcohol and the ceramic surface friction chemical reaction, the friction and abrasion film formed on the ceramic surface reduces the friction coefficient and wear volume.
