Through the X-ray method, synthetic remarkable effect of surface hardening due to highspeed submerged water-jet-peening and the corresponding mechanism is quantitatively investigated, for two cases with and without carburizing upon the tooth gear surface manufactured by SCr420H steel, when the jet is accompanied by uniformly large bubble cloud. Clearly, the effect is remarkably improved by such carburizing quenching.
