FIELD: weapons and ammunition.
SUBSTANCE: axially symmetric ammunition surface by laser ablation microstructure is created in form of directed at angle α= 15°-90° to ammunition axis furrows with depth of h to 50 mcm and with pitch of t = 20-70 mcm. Laser beam exposure on surface of ammunition during its rotation around its axis with simultaneous movement of focused laser beam on processed surface along axis of ammunition to produce said relief microstructures on which antifriction material is applied.
EFFECT: improved ballistic performance of ammunition.
