碳纳米管增强胶黏陶瓷涂层的制备及性能表征
|
摘要
利用溶胶凝胶法制备了胶黏陶瓷涂层,为了提高涂层的综合性能,在涂层中添加了少量的羟基化碳纳米管。对涂层的形貌、显微硬度、摩擦磨损特性进行了分析,结果表明:添加碳纳米管的涂层光滑平整且碳纳米管在涂层中分散均匀;添加0.3wt%碳纳米管的涂层,显微硬度达到最大值750 HV,碳纳米管再次增加时,显微硬度开始下降;植入0.5wt%碳纳米管的涂层,摩擦系数和磨损量分别为0.35和0.573×10~(-3)mm~3/Nm,涂层的摩擦磨损特性最佳。
Ceramic coatings were prepared by sol-gel process. In order to improve the comprehensive performance,the proper amount of carbon nanotubes was added. The micro topography,micro hardness,friction and wear properties were studied. The experiment conveys that the structure for the coatings is compact and close,and the carbon nanotubes were dispersed homogeneously in the coatings; the average micro hardness gains the maximum value 750 HV when the carbon nanotubes amounts to 0. 3 wt% in the total quantity and then the average micro hardness begins to decrease when the carbon nanotubes is added continually; the friction coefficient gains 0. 35 and the wear property gain 0. 573 × 10~(-3)mm~3/Nm when the carbon nanotubes amounts to 0. 5 wt% in the total quantity with the best performance for friction and wear property.
