Abstract

High chromium martensitic stainless steel has been surfacely treated by pulsed Nd:Glass laser. The temperature fields at the surface and in the bulk during the laser pulse and following cooling stage have been estimated with a numerical simulation. The modification of structure parameters has been analyzed by X-ray diffraction both in standard Bragg-Brentano and grazing incidence beam geometries. It has been found that the laser treatment modifies the surface parameters as follows: introduces residual macro-stresses, vacancies and dislocations, increases significantly (with 90%) Vickers micro-hardness at the surface and causes formation of a very thin oxide film.
