The modelling of heat, mass and solute transport in surface processing with laser radiationerial processing with laser radiation is reviewed. Some recent results due the Stefan-Problem in surface melting, mass transfer mechanisms in laser surface alloying and 3D free surface deformation calculations because of density variations due to phase transformation are presented.

One-Dimensional Thermal Model Including the Dependence of Absorptivity on Temperature using Hagen-Ru a particular laser setup and for a certain practical requirement, such a relation is quite useful for the purpose of process optimisation. For instance, in pulsed laser irradiation, when the requirement is that a definite value of temperature is attained at the surface (e.g. the melting temperature

With titanium substrates the objective has been to enhance the resistance to high temperature oxidation and to erosion through the formation of FGM coating layers containing aluminium. In the alloying process, alu
