The electron beam physical vapor deposition (EB-PVD) process is often used to produce thermal barrier coatings (TBCs). This method has a wide application in the aerospace industry. The computational model can contribute to enhanced control of the coating process by improving efficiency. In this work, a ray tracing based finite element model has been developed. Assuming a line-of-sight coating process and considering the shadow effects. The model is successfully validated by coating prediction on regular shaped components, and modeling results are in good agreement with either the raytracing-based analytical solution or experimental data. Then a coating thickness prediction in a rotary gas turbine blade is demonstrated.
