开发了一种利用空化冲击进行喷丸的方法。在这种喷丸方法中，空化气泡是由空化射流产生的。为了提高喷丸强度，在空化射流周围注入了低速水射流，水射流扫走了残留气泡，从而削弱了空化冲击。本文研究了利用空化射流和伴随水射流来提高不锈钢的疲劳强度，并与常规空化射流的结果进行了比较。结果表明，与常规空化射流相比，空化射流结合水射流能更有效地对不锈钢进行喷丸处理。
Peening method using cavitation impacts have been developed. In this peening method, cavitation bubbles were generated by a cavitating jet. In order to increase peening intensity, a low speed water jet was injected around a cavitating jet, as the water jet swept away residual bubbles, which weaken the cavitation impact. In the present paper, improvement of fatigue strength of stainless steel by using a cavitating jet with an associated water jet was investigated compared with the results of conventional cavitating jet. It was concluded that the cavitating jet with an associated water jet can peen the stainless steel more effectively compared with the conventional cavitating jet.
