Abstract
Chromed layers are formed on bodies of iron, nickel or their alloys, or of metals of still higher melting points such as molybdenum, tungsten, tantalum, columbium and their alloys, by exposing the body to the action of a chromium containing copper melt and removing the surplus melt after the formation of the chromed layer. The surplus copper melt may be removed chemically, electro-chemically or by vacuum evaporation. The article may be dipped into a chromium copper melt, or the alloy may be applied by spraying, electroplating, or powder deposition, and then melting the alloy coating. The copper melt may contain 0.5-25% chromium of which up to 35% may be replaced by silicon, up to 20% by boron or by a combination of up to 25% silicon and up to 15% boron. To reduce the chroming temperature, up to 50% of the copper may be replaced by tin, silver, cadmium, aluminium, lead, gold or zinc. A layer of diffused aluminium or beryllium may be superimposed on the chromium after the copper has been removed.
