发明名称 Composite steel and ceramic gun barrels
摘要 A method for lubricating gun barrel bores comprises burnishing dry lubricating ceramic particulate into the metal surface of the bore such that the particles of particulate substantially fill grain boundaries in the metal. The burnishing of the particulate may be done manually or mechanically. Mechanically burnishing the particulate includes firing particulate-coated ammunition projectiles or other ammunition-firing pieces coated with particulate.
