Abstract

1382009 Coating substrates with carbide layers TOYOTA CHUO KENKYUSHO KK 1 May 1973 [4 May 1972 12 April 1973] 20630/73 Heading C7F A substrate containing at least 0À05% C which is Fe, Fe alloy or cemented carbide is formed with a carbide layer by immersion in a molten bath of boric acid or borate in which a Group Va element (V, Nb, Ta) or an alloy thereof with e.g. Fe, Ti, Zr, Hf, Mn, Si, Al, Mg, Ca or rare earth elements is anodically dissolved by making a block of the element the anode and the bath vessel the cathode. The bath may also contain a chloride or fluoride of an alkali metal. The cemented carbide is WC and may include Co, and carbides of Ti, Nb, Ta.
