This coating technique uses the physical deposition method, where titanium alkoxide (lump of titanium) is placed in high vacuum. Then + voltage is applied to titanium and - voltage is applied to the product that needs to be coated. This generates titanium particles that, in high vacuum, adhere to the product under - voltage forming its coating.

Metal is evaporated in the vacuum using different sources of energy like an arc, heat, electronic load, then activated using plasma or ion beam to form the required surface. There are several methods that are used to evaporate metal and increase its reactivity during the coating process. For heavy and large parts like tools or molds, plasma cleaning and ion bombardment are required to increase the adherence.

How effective the cleaning and coating process is affects the performance and longevity of the molds and tools being manufactured. The recent development of the PVD technology resulted in a new process technology allowing for a significant progress to be made. And this cutting-edge functional surface treatment method has greatly benefited several areas including the automotive, electrical and electronic industries.
