Tungsten coating

Conventional methods are only able to liquefy tungsten powder and spray it onto the work piece. The impact of the individual droplets striking the piece results in a very rough surface. But the plasma generators which Dr. Laure Plasmatechnologie GmbH uses evaporate tungsten powder, thus yielding smooth, reflective coats of tungsten deposited on a wide range of substrates.

With a melting point of 3,422° C, the layers of tungsten are highly resistant to high heat loads. They are also suitable for protecting components from many different environmental effects, such as chemical attack and/or wear.

These layers of tungsten can also be used as the basis for tough tungsten carbide coatings, tungsten boride coatings or reflectors for solar absorbers, which operate at high temperatures.
