ABSTRACT:
A coating mixture for use in aluminizing metal surfaces comprises 5 to 50% by weight of an organic resin binder, 2 to 25% by weight of one or more halides and the balance finely divided particles of an aluminium-containing alloy. The alloy has a melting point of at least 1100.degree. C and contains 40 to 60% by weight of aluminium, the balance comprising iron, cobalt, nickel or zirconium or any combination thereof. The coating mixture is applied to the metal surface to be aluminized and then heated in an inert or reducing atmosphere at a temperature of 800.degree. to 1100.degree. C for a time sufficient to enable at least some of the aluminium in the alloy to diffuse into the metal surface.
