Abstract
A method for processing a substrate article is provided. The method includes masking a first portion of the substrate article with a maskant that includes a formed graphite piece that overlays and contacts the first portion of the substrate such that a second portion of the substrate is not overlaid nor contacted by the maskant; and processing the substrate article such that a coating of material is deposited on the second portion of the substrate, and wherein the maskant facilitates preventing the coating from being deposited on the first portion of the substrate article.
