| Abstract: | The thermal interaction between metal/ceramic particles and their contact interface in the process of plasma spray is investigated numerically by means of the ANSYS finite element program The temperature time relation and the method of simulating temperature at the contact interface are described In particular, the thermal interaction between different particles, including those among single metal particle (Ni) and single ceramic particle (Al 2O 3) and the contact interface is taken into account in modeling the process of a functionally gradient material (FGM) These numerical results provide necessary theoretical basis for investigations on the firm bondage between coatings |
