"Repair method of components covered with adhesive employing roofs of NiAl.In a way of realization of the invention is described a method for repairing a coated component, which has been exposed to the operation of the engine.To restore the dimensions covered component and increase the operational efficiency of the engine.The method comprises providing a component used in an engine including a substrate of base metal.The substrate has a metallic base on this roof system comprising a thermal barrier coating adhesive on the substrate of metallic base and a cover of the barrier tu00e9rmicThe ceramic top. The coverage of thermal barrier ceramic top has a nominal thickness t.The method further includes removing the covering system of thermal barrier, and a part of the metallic base substrate is also removed, and determine the thickness of the plate removed.The part of the metallic base substrate removed has a thickness 30 t.The method also includes applying an adhesive to cover sobrecamada of NiAl phase 225, and determine the difference of thickness 30 x,Between the adhesive coverage of sobrecamada of NiAl phase 225 and the adhesive coverage previously removed.The method also includes reapply a thermal barrier ceramic top cover until the nominal thickness of T + 30 T 30 x,Since 30 t compensates the part removed from the substrate to metallic base.Advantageously,The dimensions of the component covered are restored to approximately the dimensions covered prior to the operation of the engine to increase the operational efficiency of the engine.
