Title: Methods of removing a ceramic coating from a substrate

Abstract

A method for removing a ceramic coating from a substrate is presented. The method includes contacting the ceramic coating with a composition including a fluoride source and nitric acid. A method of forming a component having a variation in saturation magnetization is presented. The method includes masking selected portions of a surface of a metallic component using a ceramic coating to form a masked metallic component; selectively diffusing nitrogen into the metallic component by exposing the masked metallic component to a nitrogen-rich atmosphere; and removing the ceramic coating from the surface of the metallic component by contacting the ceramic coating with a composition including the fluoride source and nitric acid.
