| Abstract Scope |
In this study, the water jet caviation peening (wjCP), merged laser shock peening (mLSP), shot peening (SP), water jet shot peening (wjSP), and multi-pin ultrasonic impact peening (UIP) are applied for surface modification to enhance the surface properties of AISI 304 austenitic stainless steel. The plane specimens were processed by the optimized peening parameters. The effect of these advanced mechanical surface treatments on the surface texture, roughness, hardness, grain size, and hardening depth are compared and discussed. The electrochemical corrosion behavior of peened stainless steel parts is also addressed. The corrosion tests were performed in 3.5% NaCl solution at room temperature using an open circuit potential, linear polarization resistance, cyclic polarization, and potentiostatic/potentiodynamic polarization measurements. Results showed that the applied peening techniques led to an increase in the surface hardness due to grain refinement. The most significant increase in the corrosion resistance was observed after the ultrasonic peening. |
