Tantalum is one of the elements with the highest melting point, so it is well suited as a heat shield. Furthermore, tantalum is characterized by a high chemical and mechanical resistance so that the coated components are protected against high temperatures, but also against almost all aggressive chemicals and against mechanical stress. Due to the high melting and boiling points it is difficult to produce a homogeneous, smooth a dense tantalum layers.
Conventional coating processes produce either thick, but very rough layers in a short time (thermal spraying) or homogeneous, smooth and also in spite of long time very thin coating views (sputtering). With an arc-plasma facilities from Dr. Laure Plasmatechnology GmbH however, it is possible to produce homogeneous and smooth tantalum layers with a high deposition rate, as powerful plasma torches can vaporize the tantalum directly

Metallic coatings can be used to protect and refine components in many different ways.
Dr. Laure Plasmatechnologie GmbH has years of experience in methods for depositing metallic layers on a wide range of surfaces and components.
The extremely high temperatures in our arc plasma generators are capable of evaporating any metal – even tungsten, which has a boiling point of 5660° C.
We have successfully applied coatings with the following materials to date:
Bor, Aluminium, Silizium, Titan, Chrom, Eisen, Nickel, Kupfer, Zink, Germanium, Selen, Yttrium, Zirconium, Molybdän, Palladium, Silber, Cadmium, Indium, Zinn, Tellur, Tantal, Wolfram, Iridium und Gold, sowie verschiedene Legierungen der genannten Metalle.
