Dynamic process for enhancing the wear resistance of ferrous articles |
摘要 |
A dynamic process for increasing the wear life of ferrous articles subjected to a high-temperature environment created by combustion of a propellant or fuel comprises selecting the propellant or fuel so that its combustion products include relatively large amounts of nitrogen, which nitrogen forms a protective nitride layer on the surface of the ferrous article. Disclosed is a specific embodiment of the invention for prolonging the wear life of gun barrels.
