Abstract

1352661 Sintered iron alloys TOYOTA JIDOSHA KOGYO KK 28 Jan 1972 [28 June 1971] 4177/72 Headings C7A and C7D A sintered alloy especially suited for the valve-seats of internal combustion engines, is comprised of an iron-base sintered skeleton containing by weight:- the remainder being iron, the pores of the skeleton being infiltrated with copper, lead antimony, a copper-based alloy, copper-lead or copper-lead-based alloy, or a lead-based alloy. Preferred components of the infiltrant alloys include tin, zinc, chromium, bismuth, antimony and cadmium. The sintering step is generally effected under a reducing gas atmosphere.
