SLURRIES FOR PRODUCING ALUMINIUM-BASED COATINGS |
摘要 |
A slurry comprises suspended aluminium particles in a colloid having dispersed colloidal particles of a metal oxide such as a hydroxide. The metal oxide is reducible by metallic aluminium. The slurry has such a basic pH that dissolution of the aluminium particles in the slurry is inhibited so that when the slurry is subjected to a heat treatment, the undissolved aluminium particles are reactable with the colloidal particles to form an aluminium-based mixture resistant to chemical attack made of aluminium oxide, metal aluminium and the metal of the colloidal particles. The slurry can be used to form an aluminium-based protective coating on a component, in particular of an aluminium electrowinning cell or an apparatus for treating molten aluminium. |
