Abstract

Cold-embrittled parts are surface treated by an abrasive jet through the use of an arrangement which includes as a centrifuge wheel. The centrifuge wheel is self-priming and is connected to a granulate collecting tank via a suction pipe with a spray nozzle for low boiling liquefied gas being arranged in the inlet zone of the suction pipe. The resulting abrasive jet pattern is of the same shape and size as the treatment surface.
