Abstract

Zirconium alloys suffer from inadequate abrasion and corrosion resistance under harsh operating conditions, posing a significant challenge to reactor safety. The evolution of microstructure, microhardness, and abrasion and corrosion resistance of the Zr-4 alloy after LSP treatment with different laser pulse energies was investigated. In this study, a plastic deformation layer formed near the surface of LSP-treated Zr-4 alloys, and increasing laser pulse energy slightly raised surface roughness. The microhardness exhibited a typical gradient distribution relative to the distance from the surface. The Zr-4 alloy treated by LSP with a laser pulse energy of 6 J demonstrated better resistance to abrasion and electrochemical corrosion, which can be attributed to the appropriate plastic deformation layer and surface roughness.
