Abstract
This paper presents a study on the effect of intergranular oxidation on the bending fatigue strength of case-hardened gears. The test gears were case-hardened by gas-carburizing and vacuum-carburizing methods, and the degree of intergranular oxidation and the grain size of these gears were examined. Bending fatigue tests for these gears were carried out, and the effects of intergranular oxidation on the bending fatigue strength of case-hardened gears were clarified. Furthermore, various mechanical surface treatments (shot peening, shot blasting, etc.) were performed on these gears, and the effect of these surface treatments on the bending fatigue strength after case-hardening was investigated by carrying out bending fatigue tests.
