Low Friction Coefficient

I am prototyping a design that calls for a large wear surface with a low friction coefficient when the opposing material is PTFE.

Solid alloys or coatings are acceptable as long as the wear resistance of the coating is good.

Any suggestions would be appreciated.

You already have 90% of the friction problem solved by having an opposing surface made of Teflon. This material has the lowest friction properties of all. So, you only need to assure the less damage possible to the other surface depending on environment or particles in between. You didn't give details but depending on gross and point loads you may opt for anything from brass (mid soft) to hardened, chrome plated and ground steel or even ceramic or carbide coatings. These arrangements are used in heavy duty or hydraulic equipment all the time with excellent results. G. Marrufo-Mexico
