Description	Jedním z problémů, které je třeba brát v úvahu při technické realizaci impulzního silnoproudého kapilárního výboje je životnost použité kapiláry. Zde předkládáme výsledky studia vnitřního povrchu korundové kapiláry po několika stech výstřelů v aparatuře CAPEX. Ukázalo se, že životnost kapiláry je limitována členitou sklovitou vrstvou, utvářející se na jejím vnitřním povrchu. Tato vrstva je zřejmě vytvořena nataveným materiálem kapiláry a má velmi pozoruhodnou strukturu. Jeji motivy a hloubka se mění se vzdáleností od konce kapiláry. Vedle detailních mikrofotografií prezentujeme také pracovní hypotézy, navrhující vysvětlení vzniku této vrstvy. (cs) One of the problems that have to be taken into account during the technical realization of the pulse high-current capillary discharge is the life-time of the applied capillary. We are presenting here results of our investigation of alumina-capillary inner-surface after several hundred shots in the CAPEX device. It was found that capillary life-time is limited by a rugged glassy layer forming on its inner-surface. The layer seems to be formed by partially melted material of the capillary and has a very remarkable structure. Its motifs and depths change with the distance from the capillary-end. Besides detailed microphotographs we are presenting our working hypotheses that suggest explanation of layer formation.
