Abstract: A method of depositing a coating on a component of a turbine engine. The method includes forming a turbine component including at least one cooling flow passage in fluid communication with an aperture on a surface of the turbine component. A protective shield is formed on an inner surface of the at least one cooling flow passage and extending to an exterior of the turbine component via the aperture. During a coating process, the protective shield is configured to block the coating from being deposited in the at least one cooling flow passage via the aperture. Subsequent to coating, at least a portion of the protective shield is removed to provide for passage of a cooling fluid flow in the at least one cooling flow passage. The cooling fluid flow exits the turbine component through the aperture. A turbine component employing user of the protective shield is also disclosed.

Abstract: A method for protecting a coating on a surface of a component is provided. The method includes a coating step for coating at least a portion of the component with a ceramic slurry. A projecting step is used for projecting a pattern of light onto the component with a lithographic process to expose and solidify a ceramic layer. A removing step is used for removing unexposed portions of the ceramic slurry from the component. A heating step heats the component to sinter the ceramic layer. The ceramic layer comprises multiple ridges with each of the ridges having a curvilinear pattern.

Abstract: A process of treating a coated article and a treated article are disclosed. The process includes providing an article having a MCrAlY coating, applying an aluminide treatment onto the MCrAlY coating to form a treated MCrAlY coating, and outwardly forming β-phase material from the MCrAlY coating into the treatment. The applying is selected from the group consisting of soaking, spraying, brushing, dipping, pouring, pack cementation, vapor deposition, and combinations thereof. The treated article includes a substrate and a treated MCrAlY coating positioned on at least a portion of the substrate. The treated MCrAlY coating includes a β-phase aluminide in a spray-applied, brush-applied, pour-applied, dip-applied, pack cement-applied, vapor deposit-applied, or soaking-applied treatment.
