Title (EN) ABRASIVE PROCESS FOR MODIFYING CORNERS, EDGES, AND SURFACES OF CAPACITOR ANODE BODIES
(FR) PROCESSUS D'ABRASION POUR MODIFIER LES COINS, LES BORDS ET LES SURFACES DE CORPS D'ANODES DE CONDENSATEURS
Abstract: front page image
(EN)Porous sintered anode bodies for capacitors formed from valve metals are treated by electrolysis to form a dielectric layer and coated with cathode layers. When standard parallelepiped shapes are used as they were pressed, cathode coverage at the sharp corners and edges is non-uniform and failures occur at those locations. Treating pressed anode bodies with an abrasive process alters the sharpness of corners and edges, creating rounded transitions between primary surfaces, and removes surface imperfections resultant from the pressing process, both of which enhance cathode layer uniformity.
(FR)Des corps d'anode frittés poreux pour des condensateurs formés à partir de métaux valves sont traités par électrolyse pour former une couche diélectrique et revêtus de couches de cathode. Lorsque des formes parallélépipédiques standards sont utilisées, telles qu'obtenues par pression, la couverture de la cathode aux coins pointus et aux bords vifs n'est pas uniforme et des fissures apparaissent à ces emplacements. Le traitement des corps d'anode pressés par un processus d'abrasion modifie le caractère pointu et vif des coins et des bords, de façon à créer des transitions arrondies entre les surfaces principales, et élimine les imperfections superficielles résultant du processus de pression, ceci améliorant l'uniformité des couches de cathode.
