Physical Vapor Deposition Simulations of Microstructure Evolution
Abstract
Physical vapor deposition (PVD) is currently being explored as an alternative to electrodeposition for coating the bore of large caliber cannon. PVD is an efficient and environmentally friendly means of producing protective coatings. A number of experimental PVD systems have been developed using cylindrical magnetron sputtering (CMS) to provide a thick metal coating on the bore of cannon. However, adherent, erosion and corrosion resistant coatings are critical to the performance of many weapon systems and the process control parameters that produce the optimal coating properties have not yet been identified. A number of promising coatings have been produced, but a significant number of costly experiments are required before these parameters can be established. Therefore, there is a need for further guidance in selecting the experiments. A model capable of predicting important coating properties such as adhesion, cohesion, density, compositional variation, and uniformity is desirable, but currently not available.
