- Laser Shock Peening of Duplex Stainless Steel in Comparison with Other Methods of Surface Treatment
この論文をさがす
抄録
Duplex stainless steel (DSS) provides excellent mechanical strength and corrosion resistance and its application has been expanding to diverse industrial fi elds where strong corrosion resistance and mechanical strength are simultaneously desired. For the enhancement of surface hardness and wear resistance of DSS, various surface treatment techniques have been adopted previously, which however produced mostly minor improvement of corrosion resistance or occasional degradation of corrosion behavior. In this study, the results of laser shock peening of DSS are presented in comparison with those of previously attempted methods. It was demonstrated that the surface hardness, wear resistance, and corrosion resistance of DSS can be simultaneously increased by properly applied laser shock peening process. The maximum surface hardness enhancement of 29%, wear volume decrease of 66%, and corrosion rate decrease of 74% were achieved by water immersion type laser shock peening and similar results were also obtained by nozzle type laser shock peening.
