Abstract

A model of the fluid flow and heat transfer of laser surface alloying is presented. The general three-dimensional governing equations are first considered. Their non-dimensional form is derived. A limiting case is considered - line source parallel to scanning direction. Governing parameters are derived and their significance is discussed. A numerical solution for a line source parallel to scanning direction is obtained. The flowfield within the molten pool and the shape of the molten pool thus obtained are presented. The predicted heat affected zone is shown. Characteristics of the process in the presence of the flowfield are discussed.
