evolution of black thin film

In the world of decorative thin film, black color has always been considered a technological and technical limit. In the galvanic field, to obtain black color, are usually used elements, such as cobalt, chromium and nickel, those latter are harmful to human’s health and dangerous to the environment. Furthermore, it is extremely complicated to ensure stability at the process and the wear resistance is quite poor.

Protec Surface Technologies new solution, using an innovative PVD process, is environmental friendly and completely safe for human health.

Protec Surface Technologies has focused its attention to the development of black PVD color having very good characteristics of stability, repeatability and speed of execution. Using different combinations of metals and evaporation techniques  it’s possible to combine, black thin film specific properties, low L coordinate and high mechanical properties.
