Aluminium wetting against iron


My problem is somewhat different but perhaps someone can help. I want to improve the wetting of liquid aluminium against cast iron. Does anyone know a coating that could be applied to the iron to improve the wetting?

Brush on silica gel or magnesium hydroxide from an aqueous suspension. Sodium silicate solution will probably work as well and may adhere better. The liquid aluminum wets the silica (or magnesia), creating a tiny thermite reaction. A coating of magnesium or zinc would also work.

Aluminum wetting against iron . I read the answer (by Mr. Ken Vlach) concerning the use of magnesium hydroxide in aqueous suspension to improve the wetting of liquid aluminum against cast iron.
I'd like to know more about this suggestion. For example which is the best concentration on MgOH in water and all is useful to apply this tip.
