1. A method for treating a surface of a metal body comprising applying a graphite coating to the surface to be protected, and applying a material reactive with the metal body on the uncoated surface. 2. A method for treating a surface of aluminum comprising applying a graphite coat to one surface of an aluminum body, and applying a material reactive to aluminum on the uncoated surface. 3. A method for protecting the exterior of an aluminum container during boding to a uranium slug comprising applying a graphite coat to the exterior surface of the container, and applying a bonding agent reactive to aluminum, to the interior surface of the container and the slug. 4. A method for protecting the exterior of an aluminum container during immersion in an aluminum-silicon alloy comprising applying a coating comprising colloidal graphite in water to the exterior surface of the container, and applying an alloy containing aluminum and silicon to the interior surface of the container. 5. A method for protecting the exterior of an aluminum container during immersion in an aluminum-silicon alloy comprising applying a coating to the external surface of the container, the coating comprising colloidal graphite in water, permitting the coating to dry, and applying an alloy of aluminum and silicon to the interior surface of the container at a temperature between 588.degree. and 594.degree. C. 6. A method of jacketing a uranium slug to an aluminum container comprising applying a coating to the exterior of the container, the coating consisting of colloidal graphite in water, permitting the coating to dry, applying an alloy of aluminum and silicon to the interior surface of the container at a temperature between 588.degree. and 594.degree. C., inserting the slug into the container in complete contact with the alloy, and quenching the assembly. 7. A method of jacketing a uranium slug to an aluminum container comprising applying a coating to the exterior of the container, the coating consisting of colloidal graphite in water, permitting the coating to dry, applying an alloy of aluminum and silicon to the interior surface of the container at a temperature between 588.degree. and 594.degree. C., inserting the slug into the container in complete contact with the alloy, and quenching the assembly, the time interval between applying the alloy and the quenching being a maximum of forty seconds.
