[QUOTE="Lasiter, post: 1633111, member: 80480"] To start with Cerakote, it would depend on how skilled the coater and preparation would be regarding clearances between the bolt and action. Not enough clearance/too thick Cerakote and you'll be very unhappy. (On my guns, I would want Ceracote for the exterior only and keep it out of the works.) Long engagement of the bolt and action, all other things being equal, might be smoother than shorter engagement. (Long engagement resists cocking.) Two different materials usually slide against each other better than two identical materials. An example is early attempts at all stainless steel semi-auto hand guns where soft (300 series) stainless was used and the slides would near weld themselves to the frames. Simple fix: leave the frame uncoated and coat the slide with .0002-.0004" electroless nickle. (Hard chrome or titanium nitride would work also.) I would want to start out with a bolt/receiver design that is inherently smooth, then polish the contact surfaces mirror-smooth. THEN worry about corrosion resistance, because a light coat of good lubricant and regular cleaning will prevent most corrosion. I'd stick to thin hard coatings like titanium nitride, boron nitride, etc. Try all your friends' rifles to see what feels good to you. [/QUOTE]
