This study presents a validated high-fidelity model of Electron Beam Physical Vapor Deposition (EB-PVD) process that can predict the coating thickness on samples on a rotating stage. Two simulation techniques were developed to compute coating thickness. The first one is a ray tracing (RT) method, assuming a line-of-sight coating process and taking the shadowing effects into consideration. The second one is based on heat transfer method. The thickness is predicted based on the calculated temperature profile. Case studies of coating thickness prediction on different part geometries, including a gas turbine blade, will be demonstrated.
