摘要

PPROBLEM TO BE SOLVED: To form different aluminide-diffusion coatings on different regions of a superalloy member such as a gas turbine engine blade and a vane. PSOLUTION: The substrate is subjected to a vapor-phase aluminizing by placing the substrate in a coating chamber in which an aluminum-containing coating gas flows and heating the substrate to an elevated coating temperature inside the coating chamber in the presence of the coating gas. In the coating chamber, a first surface region of the substrate is surrounded by a masking enclosure having one or more coating gas inlet apertures that communicate to an interior chamber with the coating gas in the coating chamber, and a second surface region of the substrate is freely communicated with the coating gas in the coating chamber. By heating the substrate, an aluminum-diffusion coating growing outward and the aluminide-diffusion coating growing inward are simultaneously formed on the first and second surface regions, respectively, of the same substrate.

要解决的问题：在诸如燃气涡轮发动机叶片和叶片的高温合金构件的不同区域上形成不同的铝化物扩散涂层。

解决方案：通过将基板放置在其中流过含铝涂料气体的涂布室中，并在有涂层的情况下将基板加热到升高的涂布温度，对基板进行气相镀铝。涂层气体。在涂覆室中，衬底的第一表面区域被具有一个或多个涂覆气体入口孔的掩蔽罩所包围，所述掩模气体入口孔与内部腔室连通，并且涂覆气体在涂覆室中，并且衬底的第二表面区域是与镀膜室内的镀膜气体自由连通。通过加热基板，分别在同一基板的第一和第二表面区域上同时形成向外生长的铝扩散涂层和向内生长的铝化物扩散涂层。
