What is PVD?

PVD is the acronym for “Physical Vapour Deposition”. It is a very peculiar and innovative coating system. Actually, it is not a regular way of coating because the transfer of material occurs in a vacuum room with a temperature of 400 C. Steel and titanium bond at a molecular level.

PVD is used in several fields as an alternative to common coating techniques, solving some of the most common issues and enhancing the quality and technical characteristics.

Starting from different kinds of the substrate (the composing material of the object to be coated) such as brass, zamak, aluminum, steel, titanium up to plastic, glass/crystal, ceramic, carbon fiber, various materials are deposited. Some of them are zirconium (Zr), titanium (Ti), chrome (Cr), titanium-aluminum (TiAl), aluminum-titanium (AlTi), aluminum-chromium (AlCr), blended with technical gases such as nitrogen (N), Oxygen (O2,), Acetylene (C2H2,), Methane (CH4).

These combinations allow us to obtain High surface hardness (HV > 1800), high resistance to the aggressive actions of salt spray, and other atmospheric agents. Moreover, PVD ensures higher resistance to many products for domestic and industrial use.
The possibility to have a wide range of achievable colors added to its atoxcity and zero-impact production chain round off its main features.
