MOLTEN ALUMINUM RESISTANT ALLOYS

摘要

Embodiments of methods for protection a material from a reaction from molten aluminum. In some embodiments, a coating can be applied over a substrate which has significantly less of a reaction rate with molten aluminum, thus preventing damage or chemical changes to the substrate. The coating alloy can be formed from cast iron in combination with niobium in some embodiments.

主权项

1. A method of protecting a component from molten aluminum reaction, the method comprising:
coating a component formed from a base material with an alloy; wherein the alloy has a reaction level to molten aluminum of less than 38 atomic %, the reaction level being calculated by determining a minimum alloy content in a pseudo binary alloy/aluminum phase diagram where the liquidus temperature is at or above 1500K; and wherein the alloy has a minimum concentration of highly resistant secondary phases of 5 mole %.
