Abstract

Sea-water valves, valves for internal combustion or steam engines, and other ferrous alloy parts which are subject to corrosion, are coated first by pressure, fusion or any other convenient method with a non-ferrous alloy having a melting point above 1100 DEG C., and then by fusion with a heat- and corrosion-resistant alloy having a melting point above 1200 DEG C. This second alloy may also be used for the first coating, which latter may be machined to reduce its thickness to the minimum required to insulate the second coating from the ferrous part. The first alloy may consist of 80 per cent nickel and 20 per cent chromium, with or without one or more of the following: carbon up to .15 per cent, silicon up to .2 per cent, manganese up to .4 per cent, and cobalt up to .2 per cent; it has a melting point of 1380 DEG C. The second alloy may consist of 9.5-11.5 per cent aluminium, 9-11 per cent chromium, 1.5-3.5 per cent molybdenum, .1-.7 per cent cobalt, .05-.15 per cent carbon, .05-5 per cent manganese, .1-.3 per cent silicon, the remainder being nickel with or without up to a total of .5 per cent of one or more of calcium, magnesium, barium, boron, strontium, zinc, cerium and other rare earth metals, and misch metal, up to a total of .5 per cent of titanium, vanadium, zirconium, tantalum, beryllium, niobium, silver, antimony or tin, and up to .3 per cent nitrogen; it has a melting point of 1385 DEG C. This second coating also may be machined. Specification 579,008 is referred to.
