Abstract

The plate consists of metal particles directly and integrally bonded to each other by sintering; and the plate has a density gradient in the direction of its thickness. The pref. plate has a structure consisting of several layers with different porosities or densities, esp. using two outer layers with low density sepd. by a middle layer of high density. The metal particles pref. consists of ferrous metal or Al alloys, esp. scrap cast iron turnings. The plate is pref. made by pressing metal power or turnings in a die consisting of two refractory end walls and two side walls formed by rows of heater electrodes. Plates 5-30, esp. 10-20 mm thick, with a porosity of 40-60, esp. 50%, have excellent resistance to sound and vibration.
