摘　　要：目的:比较不同上釉方法,以及不同打磨方法处理后进行上釉的陶瓷表面的粗糙度和光泽度。方法:按照不同的上釉方法以及上釉前的打磨方法将试件分为6组。对处理后的试件进行表面粗糙度和镜面光泽度测试并进行统计学分析。结果:采用绿砂石打磨后再上釉的A1、B1组瓷表面粗糙度高于其它各组(P<0.05),经绿砂石打磨后的瓷表面采用常规上釉的B1组粗糙度低于自身上釉的A1组(P<0.05),经绿砂石打磨后采用Softcut抛光头处理配合上釉的瓷表面(A2、B2组)与直接上釉的瓷表面(A、B组)粗糙度没有明显差异(P>0.05)。所有实验组的瓷表面光泽度之间无显著性差异(P>0.05)。结论:不同上釉方法,以及不同打磨方法处理后再进行上釉对陶瓷表面的粗糙度有显著影响,而对相应的光泽度没有显著影响。Objective：To compare the effects of different polishing and glazing methods on the roughness and gloss of ceramic surface.Methods：Sixty ceramic samples（VITA VMK95） were divided into 6 groups according to different polishing and glazing methods.Roughness and gloss of each ceramic sample was measured after different polishing process.The data were analyzed by ANOVA analysis.Results：The surface roughness of ceramics glazed after green stone polishing was significantly higher than that of the other groups（P〈0.05）.After being polished with green stone,the ceramics treated by normal glazing process were smoother than self-glazed ones（P〈0.05）.The surface roughness of glazed ceramics which were polished by green stone combined with Softcut Polishers（Group A2,B2） were comparable with the directly glazed（Group A,B）ones（P〉0.05）.The glosses of all the tested groups were comparable（P〉0.05）.Conclusion：Different polishing and glazing methods have significant effects on the surface roughness of ceramics,while the surface gloss of ceramics is not affected.
