Abstract: An electrochemical machining tool and method capable of rounding sharp edges that may be prone to cracking, for example, edge regions of cooling slots within dovetail slots of turbine wheels. The electrochemical machining tool includes an electrode and is secured to the component. The electrode of the electrochemical machining tool is inserted into a first slot, an electrolyte solution is applied between the electrode of the electrochemical machining tool and a second slot that intersects the first slot, an electrical potential is applied to the electrode and the turbine wheel to create a potential gradient between the electrode and the edge of the second slot, and material is removed from the edge of the second slot by displacing the electrode about and along the edge.

Abstract: A method includes applying a material coating on a surface of a machine component using a thermal spray, wherein the material coating is formed from a combination of a hardfacing material and aluminum-containing particles. The method also includes thermally treating the material coating to generate an oxide layer comprising aluminum from the aluminum-containing particles, wherein the oxide layer is configured to reduce oxidation of the hardfacing material.
