Abstract

X40CrMoV5-1 high-alloyed steel was plasma nitrided for different treatment times (3h, 5h and 7h) andtemperatures (450, 500 and 550 oC) under at a constant gas mixture (75% H 2+25% N2). The plasma nitridingproperties of X40CrMoV5-1 high-alloyed steel have been examined by evaluating phase composition, hardnessprofile, compound layer thickness, case depth and wear strength. It was found that double layers (compound anddiffusion) formed on the surface of the samples and increasing of treatment time and temperature has increasedthe layers thicknesses. It was found that plasma nitriding improves the wear strength, which depends onthicknesses and hardness of the diffusion layer, but the compound layer reduces the wear resistance by breakingoff and forming abrasive particles because of the high hardness.

Özet

X40CrMoV5-1 yüksek ala ş ımlı çeliği farklı iş lem süreleri (3h, 5h ve 7h), farklı iş lem s ıcaklıkları (450, 500 ve550 o C) ve sabit gaz karış ımı (%75 H 2 + %25 N2) altında plazma nitrürlenmiş tir. Plazma nitrürlenmişX40CrMoV5-1 yüksek ala ş ımlı çeliğin plazma nitrürleme özellikleri faz bile ş imi, sertlik profili, bile ş ik tabakakalınlığı, difüzyon tabakas ının derinliği ve a ş ınma direnci ele alınarak incelenmiş tir. İ ncelemeler sonucundaX40CrMoV5-1 yüksek ala ş ımlı çeliğin yüzeyinde ikili nitrür tabakas ının oluş tuğu ve bu tabakalar ın (hem beyazve hem de difüzyon tabakas ının) kalınlıklar ının s ıcaklık ve zamanın artış ına ba ğlı olarak arttığı tespit edilmiş tir.Plazma nitrürleme yüzeyde oluş an difüzyon tabakas ının kalınlıklar ına ve sertliklerine ba ğlı olarak a ş ınmadirencini arttırdığı, fakat bile ş ik tabakanın yüksek sertliğinden dolayı kırılarak abrasif a ş ınmaya neden olarakaş ınma direncini azalttığı tespit edilmiş tir.
