Can a titanium nitride finish be masked off?


Q. Does the technology exist to place a titanium nitride coating on either a stainless steel or titanium substrate in a masked fashion? The final product cannot be entirely coated by the titanium nitride, but must allow part of the substrate to show through.

A. Substrate materials are easily masked off for aesthetic or functional reasons all the time. Titanium nitride applied via PVD is "line of sight" so any area that is prevented from ion bombardment will not receive any coating.

Q. What can i use to cover these places so that ion bombarding does not reach there.

Either a masking or any thing else?

A. The easiest way is with a metal mask. Stainless steel is the best, but you can also mask the part off with aluminum or copper.
