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

[QUOTE="devins, post: 584330, member: 27441"] If I can throw my two cents in on the original question too, I would say this, I can mill you a ceramic throat to fit your milled throat area and bond it to your barrel. Piece of cake. I can fire it for hardening and strengthening and even glaze it and polish it for you to the point that it can handle heat and be super hard and not be an issue of retaining any contamination. Shortgrass could mill the barrel and I can make the insert. He would have to tell you what he would charge to mill the relief but I don't think I would charge much more than $1500 to $2000 for the insert and probably around $200 to bond it into the barrel and clean it up. That is kinda the rub. It is not very cost efficient. We didn't even get into the problems of what would happen when it eventually cracked and it would at some point down the road. So a coating? Yeah we work with ceramics and porcelains attached to metal every day under extreme forces too. What do they all have in common. They will all fail at the junction at some point. I know some of the world leaders in ceramics and porcelains bonded to alloys. Lots of thoughts on these ideas but not enough time to discuss that all right now. I can just tell you that is why I have one going off for melonite now. [/QUOTE]
