Laser Surface Modification for Structural Materials

Abstract

Much attention is recently paid to laser surface modification (LSM) techniques forproviding an approach in controlling compositions and structure of matal surface. IHI has been performing reseach activity for bringing LSM techniques to a degree of development such that they can be used industrially. One of these LSM techniques was actually applied to austenitic stainless steel pipes put in practical use to prevent stress corrosion cracking.
In this paper, our recent laser beam technology related to LSM and details of LSM technique applied to actual component in our company are introduced.
