Abstract: A method of providing an oxidation resistant coating is disclosed. The method includes providing a substrate having a first surface and cooling holes. A portable coating device includes electro-spark deposition (ESD) equipment and an ESD torch connected with the ESD equipment. The ESD torch has an inert gas source and a rotary electrode conductive material. The rotary electrode is positioned within the ESD torch, and is shielded by an inert gas. The rotary electrode applies a compositionally controlled protective coating to the first surface of the substrate. Then the rotary electrode is inserted into the cooling hole and generates an electrospark between rotary ESD electrode and the substrate to form a rounded edge and deposit a coating of electrode material alloy at a cooling hole edge.

Abstract: A braze gel includes a braze powder, a braze binder, and a viscosity reducer. The braze gel has a gel viscosity sufficiently low to permit dip coating of a component with the braze gel to apply a braze coating of the braze gel to the component. A brazing process includes applying the braze gel to a portion of a component. The brazing process also includes drying the braze gel to form a braze coating on the component to form a braze-coated component. A brazing article includes a component and a braze coating over a portion of the component. The component may have structural features having a spacing of less than about 5 mm and a depth of at least about 1 mm, which may be honeycomb cells. The component may be a turbine component.
