- 論文の詳細を見る
Laser-hardened S45C, SNCM439 and SMnC443H steel rollers and induction-hardened S45C steel rollers were tested using a sliding-rolling contact fatigue testing machine, and the surface durability and surface failure were investigated. The experimental results were discussed in terms of an amplitude of ratio of reversing orthogonal shear stress to hardness. The machanism of spalling failure of laser-hardened rollers was made clear, and it was recognized that the surface durability of a laser-hardened roller was possibly equal to or higher than that of an induction-hardened roller.
