TiN coatings are as hard as carbide, less than .0001 thick, extremely slippery, heat resistant and very good at resisting metals (lead, copper) sticking to their surface, so why haven't they made their appearance in the barrel bores of custom rifle shooters? This coating has been around for some time now and is proven in many fields including the cutting tool industry for both steels and carbides.
