Why is there no coatings used in rifle throats to slow erosion?

[QUOTE="theflyonthewall, post: 575370, member: 35305"] This is being posted in the 'smith section because I feel that there is definitely a more technical knowledge base in this section than in other places on LRH. The question is: Why are there no coatings being used in rifle throats to slow throat erosion? Ceramic coatings (to name just ONE) are used with success in many different applications from automotive engine parts like pistons, piston rings, combustion chambers, etc... as well as in the aerospace industries, foundry applications, etc.. Anyway, my point is that the technology and materials have been long proven in other industries and it would seem like a natural fit for barrel-burning calibers. But there has to be SOME reason that it's not used in barrel throats. I first thought that maybe the exacting tolerances of a throat was the issue, but film thickness seems to be a very controllable aspect so one would be able to measure film thickness, then simply factor it in when cutting a throat------right? Does anyone know why? [/QUOTE]
