Description

Simulation of circular saw discs coating procedure employing Physical Vapor Deposition (PVD) method. This metallization technique is used in a wide variety of other applications such as semiconductor wafers, photovoltaic cells, thin-film batteries, optical coatings, etc.. Present modeling can be utilized to optimize different output parameters of PVD: layer thickness uniformity, energetic efficiency, process duration, costs and productivity.
