A substrate article is processed by masking a first portion of the substrate article with a maskant including a foil layer overlying and contacting the first portion of the substrate article, leaving a second portion of the substrate article exposed, and a mask layer overlying and contacting the foil layer. The mask layer may be formed of a mixture of aluminum oxide and metal powders or carbon. The masked substrate article is processed to deposit a coating, such as an aluminum coating, on the second portion of the substrate article, without removing the maskant. The substrate article may instead be masked by carbon without the underlying nickel layer. After coating, the substrate article may be further processed by brazing to the first portion of the substrate article.
