APPARATUS AND METHODS FOR SLURRY ALUMINIDE COATING REPAIR

摘要

Methods for deposition of an aluminide coating (12) on an alloy component (18) positioned within a coating compartment (22) of a retort chamber (24) are provided. According to the method, the coating compartment (22) is purged with an inert gas via a first gas line (42); a positive pressure is created within the coating compartment (22) utilizing the inert gas; the coating compartment (22) is heated to a deposition temperature; and at least one reactant gas is introduced into the coating compartment (22) while at the positive pressure and the deposition temperature to form an aluminide coating (12) on a surface of the alloy component (18). Retort coating apparatus (20) are also provided.
