Abstract
1388285 Porous metal bodies; diffusion alloying GOULD Inc 25 May 1972 [2 June 1971 13 Dec 1971 (5)] 25237/74 Divided out of 1388284 Heading C7D and C7X A corrosion resistant substrate for having an NO x - reducing catalyst metallurgically bonded thereto comprises an apertured structure composed of: (a) 50-85 wt per cent of one or more of nickel, iron or cobalt, two of these three metals each constituting 0-40 wt per cent of the substrate and the third metal being present in a greater wt per cent than either of the other two, and (b) 15-50 wt per cent of chromium and, optionally, aluminium with at least 5 wt per cent chromium always being present and aluminium never exceeding 10 wt per cent. A continuously produced electro-plated nickel foil is expanded to form an apertured structure and chromium is electro deposited thereon so that it constitutes 15-50 wt per cent of the substrate. The metals are alloyed by thermal diffusion at about 2,200F in argon at a pressure of half-anatmosphere.
