Description
| - Erosion of needle electrodes in the pulsed corona discharge in water with a pulse energy of 2-3 J was investigated in dependence on the electrode material (platinum, tungsten and stainless-steel) and the solution conductivity (100 and 500 μS/cm). Erosion of electrodes remarkable increased with the higher solution conductivity for all three tested metals. The highest erosion rates were determined for tungsten while platinum was the least eroded material. In addition to the dominant melting effect, release of anode material by the electrolysis significantly contributed to the total erosion of needle electrodes. The highest contribution of electrolysis was determined for stainless-steel electrodes that released up to 40-50% of eroded metal in the form of iron ions. Peculiar protrusions were observed on the surface of eroded tungsten electrodes.

- Byla zkoumána eroze jehlových výbojových elektrod účinkem impulsního elektrického výboje ve vodě v závislosti na typu kovového materiálu elektrody (platina, wolfram, nerez) a elektrolytické konduktivitě vody (100 a 500 μS/cm). Míra eroze elektrod výrazně vzrůstala s vodivostí u všech tří kovů. Nejvyšší erozi vykazoval wolfram, platina naopak erodovala nejméně. Na erozi se vedle dominantního vlivu tání povrchu elektrody výbojem významně podílela také elektrolýza. Největší podíl elektrolýzy na erozi byl stanoven při použití nerezových elektrod (40-50%). Na povrchu wolframových elektrod byla v důsledku eroze výbojem pozorována tvorba ostrých výčnělků. (cs)
