Method for producing and maintaining a thermally insulating, erosion constraining protective coating on the inner surface of weapon barrels

In the case of a weapon with a barrel, the firing performance is improved by the powder propulsion charge, which produces the thermal and mechanical stress, having additives added to it of such a type and quantity that a cohesive, wear-resistant, high melting point coating is formed which has poor t...

Beschreibung
Zusammenfassung:	In the case of a weapon with a barrel, the firing performance is improved by the powder propulsion charge, which produces the thermal and mechanical stress, having additives added to it of such a type and quantity that a cohesive, wear-resistant, high melting point coating is formed which has poor thermal conductivity and whose coating thickness is determined by a balance state between the formation of new deposit and erosion as a result of the thermal and/or mechanical stress.
