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 μm-25 μm which allows for reliable operation under all environmental conditions including extreme environments such as hot/cold and sand/dust without the need for lubrication.
