Description
− 無機酸中で前記部品を活性化する工程、
− 酸素含有雰囲気中、380℃から420℃で前記部品を予備酸化する工程、
− ε窒化物範囲内の高い第1の窒化ポテンシャルKN,1において520℃から570℃で前記部品を窒化する工程、
− γ’窒化物範囲内の低い第2の窒化ポテンシャルKN,2において520℃から570℃で前記部品を窒化する工程。
− ε窒化物範囲内の第1の窒化ポテンシャルKN,1を有する第1の窒化工程は、部品表面のいわゆる化合物層内においても、その下にある拡散層内においても、部品の窒素吸収及びそれによる部品の硬度上昇に寄与する。
− γ’窒化物範囲内の第2の窒化ポテンシャルKN,2を有する第2の窒化工程により、前記化合物層は厚くなり過ぎない。化合物層は、高い強度を有するが、しかし同時に大変脆く、したがってキャビテーションによる負荷を非常に受けやすい。
1) 無機酸中で前記部品を活性化する工程。
2) 酸素含有雰囲気中、380℃から420℃で前記部品を予備酸化する工程。
3) ε窒化物範囲内の高い第1の窒化ポテンシャルKN,1、好ましくは1≦KN,1≦10、において520℃から570℃で前記部品を窒化する工程。
4) γ’窒化物範囲内の低い第2の窒化ポテンシャルKN,2、好ましくは0.2≦KN,2≦0.4、において520℃から570℃で前記部品を窒化する工程。
