Conferirea unei micro-geometriei prescrise a suprafețelor metalice în scopul sporirii intensității curentului de emisie termo-electrică / Dorin Guzgan // „Ştiinţa în nordul Republicii Moldova: realizări, probleme, perspective”, Сonferinţa naţională cu participare internaţională, 25-26 sept. 2015. - Bălţi. - 2015. - P. 29-32.http://hdl.handle.net/123456789/1316The paper presents results of experimental investigations aimed at the construction of cathodes for thermo-electronic emission. The method of pulsed electrical discharge machining was applied to confer a prescribed micro-geometry of the cathode active surface. Modification of the cathode surface micro-geometry involves the extraction and freezing of the Taylor cone meniscuses that are electric field and heat concentrators applied in order to increase the intensity of the thermo-electronic emission current.roAttribution-NonCommercial-NoDerivatives 4.0 Internaționalelectrical dischargesmicro-geometrymeniscusemissionthermo-electronsConferirea unei micro-geometriei prescrise a suprafețelor metalice în scopul sporirii intensității curentului de emisie termo-electricăArticle
