研究了用各种不同粒度分布的纳米金刚石抛光CaTiO3陶瓷表面。讨论了纳米金刚石颗粒大小及其悬浮液的分散稳定性对磁头表面形貌的影响,评价了由该种材料抛光所形成的缺陷和表面质量。试验分析表明。用粒径越小、粒度分布越窄的纳米金刚石抛光时试样表面粗糙度越小,而粒径越大,即使分布窄,所得的试样表面粗糙度也越大。同时,即使纳米金刚仃粒径较小,如果分散稳定性不好,也会在试样表面产生若干很深的划痕和凹坑,从而影响表面粗糙度。
By using various sizes of medium nano-diamond in polishing CaTiO3 ceramic surfaces, the effects of granularity of the nano-diamond and the stability of the suspension on the surface roughness are researched, and also the disfigurement on the polished surfaces is observed.
