Abstract:
ABSTRACT
The effect of shot peening on the contact fatigue strength of carbonitrided steel has been investigated by roller-pitting testing under conditions similar to those
experienced by automatic transmission gears. Results show that the shot peening process improves the resistance to softening and has a greater effect after carbonitriding
compared to carburizing. Consequently, the combination of shot peening and carbonitriding process improves the contact fatigue strength (pitting life) more than the
combination of carburizing and shot peening.
