Abstract:
Shot peening method has been found out to be very effective for improvement of surface structure anomalies created on surface of gas carburized steel, and this method is
widely applied to gas carburized gears for automotive use. For further improvement of strength of shot peened gears, bending tests were carried out by using specimens,
electro-polished or paper finished after gas carburizing and shot peening, in order to find out how the bending strength is influenced by the surface properties. As a
result, it was found out that both static bending strength and fatigue strength are greatly influenced by the depth of surface structure anomalies, surface roughness and
residual stress.
