heal.abstract	The heat-treatment of zinc-coated aluminium in atmospheric air was studied. The weight gain of the heat-treated zinc-coated aluminium specimens (in the range 250-350 degrees C) was found to increase following a parabolic law with increasing time for constant heating temperature. Zinc oxide (ZnO) of protective nature was found to form on their surface in the range 250-350 degrees C. Heat-treatment at 400 degrees C resulted in the formation of non-protective oxide on the surface of the specimens. Heat-treatment also resulted in the diffusion of zinc into the aluminium substrate and mainly in the diffusion of aluminium into the zinc coating. For high temperatures and large heating times the above procedure resulted in the formation of a two-phase diffusion zone consisting of nearly elemental zinc and aluminium, since the mutual solubility of these two elements is very small.
