Nitrogen ion implantation improves AISI M50 steel tribological properties through modifications on the surface layers of the material. As the nitrogen ion-implanted energy increases, both implantation depth and microhardness increase. Material mechanical performance has been significantly … Meer weergeven Nitrogen ion implantation has shown its role in enhancing steel surface properties. In this work, AISI M50 steel was implanted with nitrogen ions by using the metal vapor vacuum arc … Meer weergeven AISI M50 steel was used as a metal substrate in the formation of form C: 0.82 wt.%, Cr: 4.00 wt.%, Mo: 4.25 wt.%, V: 1.10 wt.%, Mn: 0.16 wt.%, Si: 0.13 wt.%, and Ni: 0.07 … Meer weergeven Bearing, as an integral part in various mechanical equipment, is critical for equipment performance, level, quality, and reliability of the equipment [ 1.
