微米、纳米及微/纳米复合金刚石涂层的切削性能研究
Study on the cutting properties of micro-nano-and micro/nano diamond coatings
摘要
Abstract
Chemical vapor deposition method was used to deposit micro-,nano-,and micro∕nano-diamond coatings on cemented carbide substrates,and then the cutting properties were tested.Based on the machined surface roughness and flank and rake wear of diamond coated tools,cutting properties of different diamond coatings were analyzed and failure forms and mechanisms were summarized.The results showed that the roughness of the surface machined with nano diamond coated tools was the smallest(R a =0.942 μm) and that the roughness of the surface machined with micro diamond coated tools was the biggest (R a = 1.631 μm).It was also showed that nano diamond coated tools had the largest flank wear,land width of which was about 2 times and 5 times larger than those of micro diamond coated tools and micro∕nano diamond coated tools respectively.In addition,the interfacial adhesion strength of micro∕nano diamond coating was better,so the diamond film did not exfoliate and wore less.The main failure form of diamond film coated tools was coating premature exfoliation,and the failure mechanism was mainly due to big residual stress,low chemical purity,severe internal cracks,high surface roughness and high cutting force,as well as the built-up edge.关键词
