KRAFTONWEG OY
Unique vacuum techniques - Innovative metal coating.

COMPANY PROFILE

KRAFTONWEG OY are combining research and experimental production. We are focused on developing new functional metal coatings and new methods of their deposition, including the development of coating materials which meet specific customer's requirements.

Our new technology utilizes all three components of plasma flow at the same time: droplets, vapour and plasma itself, so that the deposition rate reaches as high as 50-100 microns per hour.

Our method allows to put a coating on any metal with melting point more than 600 C.

Strong adhesion is provided by preparatory treatment process: removing of oxide films and impurities through successive bombardment by inert gases and metal ions.

Sample/substrate temperature can be adjusted and controlled within the range of 500 - 1000 °C.

Series of coatings based on Ta, Nb, Zr, Ti-6Al-4V and TiCu have been obtained and tested.
Particularly α-βTa and Ta -based coatings are formed with hardness of 200-800 HV in about 100 microns thick.

The technology is applicable for obtaining various material structures from continuous/solid ones up to really gradient and multi-layered coatings including intermetallic, as well as for evaporating nearly every metal and its combinations.
Noteworthy, our method is assolutely environmental friendly, as does not require any hazardous chemicals, high energy consumption, pollution, specific premises, etc.

You are welcome to try your own samples, should any specific issue we are happy to discuss it and find possible solutions.

Our company do not produce thin decorative coatings.
