Modelling the Processes of Ceramic Coatings by Surface Laser Treatment
Krystyna Kobylanska-Szkaradek
The paper presents a computation model describing the interaction between a laser beam and the surface of a three layer plate consisting of a nickel base superalloy with a plasma sprayed NiCrAlY alloy layer and a ceramic coating ZrO2 -Y2O3. The mathematical model of heat exchange processes was produced for a plate of finite thickness with the possibility of laser remelting of the ceramic coatings (within a certain depth), and taking into account the changes in physical properties with
temperature in the various layers of the plate.
