Description
まず、本発明の一実施の形態である実施の形態1に係る機械部品の製造方法について説明する。図1を参照して、本実施の形態に係る機械部品の製造方法では、まず工程(S10)として鋼部材準備工程が実施される。この工程(S10)では、たとえば転がり軸受の構成部品(外輪、内輪、転動体)の概略形状に成型された鋼部材が準備される。より具体的には、たとえば0.1質量%以上のバナジウムを含有する鋼であるAMS2315(航空宇宙材料規格;米国)の鋼材やJIS規格SUJ2に0.1質量%以上のバナジウムを添加した成分組成を有する鋼材などが準備され、鍛造、旋削などの加工が実施されることにより上記鋼部材が準備される。
次に、本発明の他の実施の形態である実施の形態2について説明する。本実施の形態に係る機械部品の製造方法は、基本的には上記実施の形態1に係る機械部品の製造方法と同様の工程により実施され、かつ同様の効果を奏する。しかし、上記実施の形態1ではバッチ炉1を用いて浸炭窒化工程(S30)が実施されるのに対し、本実施の形態では連続炉2を用いて上記工程が実施される。
