Numerical Simulation of Temperature Field for Laser Clad Composite Coatings

Abstract:

A three dimensional quasi-state numerical model of fluid flow ,heat transfer process in the melted pool for composite coating was developed ,and the temperature profile were successfully calculated by finite element software. Numerical results show that when the laser power is 1.5KW, the coating melts and the matrix does not melt, forming good shape; when the laser power is 1.6KW, the thermal stress increase, the binding of substrate and coating occurs crack, the experiment is agreement with that calculated.
