KRAFTONWEG OY are a company combining research and experimental production. We are focused on development of novel functional metal coatings and new methods of their deposition, including the development of materials meeting customers’ requirements. Our original coatings, based on α-β Ta, Ti, ZrTa, TiCu, Nb and other modifications, principally differ from traditional Arc-PVD coatings. We have managed to obtain novel types of coating materials from non-separated plasma-clustered flow, featuring:
- thickness of 20-150 microns with high deposition rate of 1 micron/min;
- homogeneous structure of mainly, or close to, amorphous phase, however, subject to deposition parameters could also be either fine-grained and/or micro-crystalline.
The technology has revealed perfect flexibility in terms of obtaining different structures and compositions of the material even including continuous, gradient and multi-layered coatings.
Besides α-βTa could be obtained/of interest in a form of thin sheet detached from substrate
By our method, we obtained a thick Nb coating and measuredTc - Critical temperature transition to superconducting state. So we saw that our method of coating is perfectly suitable for production of superconducting Nb coatings. Niobium coating can be applied to ceramics, stainless steel, Cu and to produce in the to produce in the form of separate films.
