概要

Super-carburizing is a new surface hardening method, by which a surface contains more carbon than eutectoid-carburizing. The surface hardened by super-carburizing has a high hardness, a strong abrasion resistance, a high temper softening resistance and an excellent pitting resistance. The super-carburizing is attempted to apply to various machine elements. In this study, we investigated the bending strength and the surface durability of super-carburized steel gears and eutectoid carburized steel gears. Furthermore, we applied a shot peening to the carburized gears, and carried out the bending fatigue test and the contact fatigue test for the shot-peened carburized gears. We also discussed the effect of shot peening on the strength of the carburized gears.
