Abstract

1325096 Producing coloured coatings on metals COMINCO Ltd 11 June 1971 [11 June 1970] 27613/71 Heading C7F A process for producing coloured coatings comprises applying to a surface an alloy of Zn, Sn, or Pb-Sn(Sn#5%) with an oxygen-avid additive, the oxides of which are capable of producing the desired light interference colour effects. The additive may be Ti, Mn, V, Nb, Zr, Th, Cd, As, Cu, Pb, Cr or mischmetal. The alloy can be applied by hot dipping, in which strip 13 is coated with e.g. an alloy of Zn and 0À1%Ti in bath 28, the strip being subsequently heated in furnace 90 while the coating is still molten to produce the desired colour. The bath 28 will have a film 38 of oxide above it and to prevent the strip picking this up, a pair of partly-submerged non-reactive rolls 40, 42 guide the strip out of the bath. The steel strip will have a surface comprising the steel base 10, an Fe-Zn layer 12, a Zn-Ti layer 14 having a reflective surface 18, and finally a layer 16 of titanium oxides. The colour of these oxides can be varied by varying the temperature in the furnace 90 or the strip speed through the furnace. If the strip 13 contains certain deleterious elements, e.g. Al, Mn, then the strip is given a pre-coating of Zn in bath 17. In another embodiment Fig.4 (not shown) the strip is prevented from picking-up surface oxide from the bath by maintaining an argon atmosphere above the bath. Commercial argon is used and the small amount of O 2 in the argon is used to oxidize the coated strip. The coating may also be applied by spraying or flowing.
