摘要：

During laser alloying, a melt pool is created at the passage of a laser beam in which mixing occurs by convection because of surface tension gradients. This mixing process in the melt bath is reported here in different alloying elements on aluminium (manganese, nickel, cobalt) and steel (nickel) substrates and a homogeneous distribution did not appear to be evident. It is concluded that density differences, interface tensions and diffusion are the main factors affecting the mixing process.
