Abstract:
A design of an experiment method has clarified the contribution ratio of various peening parameters on compressive residual stress for carburized steel by using a nozzle
type machine.
V
arious peening parameters consist of shot flow rate (15, 20, 27kg/min), exposure time (1, 5, 10sec), the distance between the tip of a nozzle and the work surface (100, 130,
180mm), shot diameter (0.6, 0.8) and shot hardness (HRC 53, 58).
T
he results were: (1) Exposure time and shot hardness have sensitive influence on compressive residual stress. (2) Shot flow rate, distance between the tip of a nozzle and
the work surface and shot size were not so significant.
T
hese results have suggested the idea to get the most efficient peening effect.
