摘要 |
To manufacture tubes having a wear-resistant inside coating, such as gun barrels, hard material layers are deposited on the barrel and the layers are strain-hardened in their surface area by at least the ratio of the area by which the surface area is reduced by compression divided by the surface area of 0.001 ( DELTA F/F=1.10-3) or reducing the area of the layer by 0.1%. |
