Abstract
Liquid aluminum is sprayed as a fine mist onto an alloyed iron article to produce a thin tenacious non-corrodible layer. In some embodiments, air is heated and delivered through insulated tubing to a container having solid aluminum therein. In some embodiments the air is heated by an electric induction coil. In some embodiments, the container is heated independently of the heated air. In some embodiments, the container is heated by an electric induction coil.
Claims11
A method of applying a thin aluminum layer to an alloyed iron article, comprising
- heating air with an electric induction coil and delivering the heated air through tubing to a compartment having solid aluminum therein;
- melting the solid aluminum in the compartment;
- and
- projecting the heated air and an aluminum mist through an outlet from the compartment onto an alloyed iron article;
- wherein the air travels through the coiled tube inside the electric induction coil and electrically separated therefrom by an insulating sheath, and the tubing is insulated tubing different from the insulating sheath.
