Abstract: A lubricant free firing weapon is provided having amorphous, solid, diamond-like carbon coating (DLC) containing sp3, sp2 carbons and hydrogen bonded to the metallic operating parts. Such firing weapons may further include physical modifications to the bolt carrier rails to enhance the expulsion of sand/dust on the bolt carrier under extreme environments. Also provided herein are plasma enhanced chemical vapor deposition processes for producing such lubricant free weapons having coat thicknesses of 1 ?m-25 ?m which allows for reliable operation under all environmental conditions including extreme environments such as hot/cold and sand/dust without the need for lubrication.

Abstract: A carrier is comprised of a thermoplastic polymer such as polyetheretherketone which is formed or fabricated as a uniform thickness, double sided flat sheet of material with wafer passages therethrough and gear teeth formed or fabricated around the peripheral edge thereof so as to be cooperative with a wafer polishing machine. An extrusion or rolling or calendering process provides a flat carrier which is, optionally, coated with thermoset polymer or thermoplastic film.
