Article Preview

In the plasma-carburizing method, the detrimental grain boundary oxides in the surface of the materials and sooting problems are eliminated and the high carbon content near the surface is easily achieved. This paper describes a study on the contact fatigue strength and wear characteristics of plasma-carburized rollers. Test rollers made of super-carburizing steel MAC14 and conventional carburizing steel SCM415 were plasma-super-carburized under different carburizing conditions. The contact fatigue tests were carried out for these plasma-super-carburized rollers. The effects of case depths on the contact fatigue strength of these rollers were determined. The effect of shot-peening on the contact fatigue strength was also examined by carrying out contact fatigue tests for shot-peened rollers. The wear tests were also carried out and then the wear characteristics of test rollers were determined. These test results for plasma-super-carburized rollers were compared with the results for gas-super- or gas-eutectoid-carburized rollers.
