FIELD: automatic small arms.
SUBSTANCE: method for preparing cover made of beryllium is based ion electron-beam evaporation of metal and its sedimentation on heated metallic backing. The sedimentation process is carried out at the backing temperature 400-600°C in the impulse regimen evaporation and pause between impulses in equal crystallization time of bath in evaporating metal. Invention provides enhancing physical-mechanical properties of the cover.
EFFECT: improved preparing method.
