Finite element modeling of coating thickness using heat transfer method

A new heat transfer based finite element model is proposed to simulate coating thickness in the electron-beam physical vapor deposition (EB-PVD) process. The major advantage of that it much computationally efficient than traditional ray-tracing by about two orders magnitude. This because Gaussian distribution heating source has same profile as cosine relation used method. Firstly, simulates temperature a metal substrate heated with distribution. Then using calibrated conversion process, converted corresponding thickness. successfully demonstrated three validation cases, including stationary disk, cylinder, and rotary three-pin component. predicted thicknesses cases are good agreement either analytical solution or experimental data. After its validation, applied turbine blade predict In summary, capable complex shaped parts.
