Wear Mechanism of Cemented Carbide Tool in High Speed Machining Iron-based Superalloy GH2132
摘要
Abstract
Four kinds of cemented carbide tools were used to turn Iron-based superalloy GH2132 at high-speed under dry cutting condition. Wear morphology of cutting tool was observed by SEM, and element distribution of tool surface was analyzed by EDS. Adhesive wear, oxidation wear and diffusion with micro-chipping were the main wear mechanisms of the cemented carbide tool . The rake face wear of the cutting tools in high speed machining was different from that in conventional speed machining. Namely, the rake face was not characterized by crater wear but by slope-plane-wear with the maximum wear at the cutting edge. Furthermore, the worn area of the rake face decreased with cutting speed and the wear depth increased correspondingly.关键词
