Abstract

Laser surface melting and alloying are important techniques to improve the properties of a material locally without affecting the bulk. In ceramic components these methods can be used to optimise the fracture toughness, friction and wear but also the thermal and electrical conductivity. Numerical computation has been performed on the basis of a finite element model (FEM) in order to get more insight in the heat and particle transport during melting and solidification.
