Micro-welded gun barrel coatings

摘要

A micro-welding process is used to apply erosion and wear resistant coatings to the internal diameter of gun barrels. The applied coatings are then treated by methods such as honing and/or rotary forging. The protective micro-welded coatings may comprise ceramic, cermet and/or refractory metal materials, and may be used with rifled or smooth gun barrels of various sizes.
