An electron beam physical vapor deposition (EBPVD) process performed with a coating apparatus to produce a coating material (e.g., a ceramic thermal barrier coating) on an article. The EBPVD apparatus generally includes a coating chamber operated at an elevated temperature and a subatmospheric pressure. The coating chamber contains a crucible and a coating material surrounded by and contained within the crucible, and the coating material has a surface exposed by the crucible. The process entails projecting an electron beam onto the surface of the coating material, wherein the electron beam defines a beam pattern having a higher intensity at an interface of the surface of the coating material with the crucible than at a central region of the surface of the coating material.
