Preliminary Evaluation of Ion Implantation as a Surface Treatment to Reduce Wear of Tool Bits.
Abstract
The process of ion implantation is reviewed and concepts for use as a surface hardening technique for extending the life of machine tools are explored. It is concluded that for high speed steel tool materials a system based on implantation of Ti ions with subsequent reaction to form TiC in the surface layers should have merit. Exploratory tests showed that in machining tests of 4140 steel, an implanted M2 lathe tool bit required about 10 percent less power and has a wear rate approximately one-half that of the unimplanted tool. Tests of end mills proved inconclusive because the optimum Ti level for the implant was not reached. (Author)
