Abstract

Vengono proposti un elemento di resistenza di superficie particolarmente liscia nonché un procedimento per la sua fabbricazione. L'elemento di resistenza è una disposizione a strato spesso, costituita di almeno uno strato (13) a pista conduttrice e di uno strato di resistenza (12) di Cermet su un substrato ceramico (14). La disposizione (12-14) degli strati viene applicata su un supporto di pressione (1) e successivamente pressato in un attrezzo di pressatura (20-22) con un substrato (14). Al termine dell'operazione di pressatura il supporto di pressione (1) viene tolto. Come substrato si impiega preferibilmente una foglia ceramica flessibile non sottoposta a cottura.(Figura 3).A particularly smooth surface resistance element as well as a process for its manufacture are proposed. The resistance element is a thick layer arrangement, consisting of at least one conductive track layer (13) and a Cermet resistance layer (12) on a ceramic substrate (14). The arrangement (12-14) of the layers is applied on a pressure support (1) and subsequently pressed in a pressing tool (20-22) with a substrate (14). At the end of the pressing operation, the pressure support (1) is removed. As substrate, a flexible ceramic sheet which has not been fired is preferably used (Figure 3).
