鋼のダイヤモンド切削における工具摩耗の抑制

-浸炭した鋼の組織が及ぼす影響-

抄録

Diamond cutting tool shows severe wear in turning of steels. In previous papers, we have showed carbides on ferrite phase precipitated by carburization suppressed the wear. In this paper, we studied on distribution of carbides by EDS analyses. Results indicate characteristics of each carbide : area, occupancy and degree of circularity, influence suppression effect of tool wear.
