Tribological analysis and performance of a DLC coating on tungsten carbide micro-tools to use at tantalum precision machining

Owing to the increasing demand in ultra-precision machining of biocompatible materials, the demand to improve the performance of cutting processes and tools becomes progressively important. To increase the performance of the micro-tools leading to longer tool life and better surface finish, applications of solid lubricant coatings are necessary. Diamond-like carbon (DLC) coatings have been successfully used in many conventional cutting tools. In...
