TiN Vapor Deposition

This is done by putting the parts into a heated container filled with nitrogen at elevated pressure.

There is a German company that is marketing these systems and vacuum furnaces.

(Unfortunately I forgot the name it is a 3letter-name).

Most applications are for nitriding steel but Ti works pretty well.

The coating thickness can be much higehr than in thin film systems.

The secret may be an unstable electrical field in the coating chamber. The process is patented by Teer Coatings Ltd of the UK, who build the machines to do it, or will offer a contract coating service.

Hi mewebe,

I think you are right for a plasma deposition it would be very beneficial to have some instability or oscillation. This can either be electrical field or magnetic field or density, also ion or electron cyclotron movements or any other of the many plasma instabilities.

(There is a book from Chen on these.)

In the simple pressure and temperature driven coating I talked about there is no electrical action at all, only temperature and pressure!

Try this link. They give several methods to obtain uniform deposition.

Good luck!
