摘要
Abstract
Presents an experimental research into the rooling contact fatigue life of GCr15 steel with Tix N, TiX N + Ag
and Tix N + DLC layers ion-implanted using the plasma ion-implantation technology on a ball-rod style high-speed con
tact fatigue tester, and concludes with test results that the fatigue life increases to varying degrees with Tix N, Tix N +
Ag, and Tix N + DLC layers implanted, and increases 1.8 times with Tix N + Ag layer implanted, hairline cracks grow
continuously into fatigue pits under the action of shear stress in the superficial layer of material, and ion-implantation
acts to prevent initiation of cracks and slow down propagation of cracks.关键词
