Low coefficient of friction coatings

Stellite, TiN?

a:CH, DLC, WC-C... there are lots of possibilities.

depends much on your intended application.

What is the base material?-Jitney

Thanks for all of your replies - more infomation;

Substrate is high strength steel max process temperature is ~400 degrees. Due to the application being on a bore, line of sight processes may not be suitable unless PVD has been delveloped for internal application?? Dry film lubricants are just not tough enough or reliable enough for the applcation. I believe accurate application to threads precludes use of thick deposits and HVOF type processes .

Copper electroplating, maybe?-Jitney

Dear Nick,

You need a solid lubricant coating to achieve a friction coefficient

Thanks Mark, I am aware of these coatings, but can they be applied successfully and evenly to an internal threaded bore ~4" Diameter?
