Temperature Field Simulation of TC4/SiC Bilayer in Laser Forming

Laser forming, an advanced technology widely used for the shaping and adjustment of metallic and non-metallic materials, can also be used to process metal/ceramic materials. Laser forming technique is based on the temperature gradient mechanism (TGM) and temperature distribution is the main factor that affects the laser forming process. In this study, the finite element method (FEM) has been applied to predict the temperature field of TC4/SiC metal/ceramic bilayer during the laser forming process. Temperature of different points in the upper surface of the metal material, interface with the two layers and the lower surface of the ceramic material has been calculated. Parameters like laser input power and laser scan-speed have been investigated. This study is aimed at providing data for the precise control of laser forming in the process of shaping and adjusting TC4/SiC bilayers.
