LASTRA METALLICA RIVESTITA CON ALMENO UNA PIASTRA DI MATERIALE CERAMICO E SUA UTILIZZAZIONE COME PALA RADIALE DI MACCHINA ROTANTE

摘要

In the case of a metal plate (1) which can be subjected to centrifugal force, at least one of its surfaces is covered by at least one plate (2) of ceramic material and the plate is characterised in that the plate (2) of ceramic material is fastened on the surface of the metal plate (1) to be covered by means of a frustoconical shell (4), which is bonded at its base to the metal plate (1) and is provided on the inside with a plug (3) of ceramic material having the same frustoconical shape. The plate can be used as a radial blade on rotating machines, in particular exhausters.
