Abstract: An article treatment method includes positioning an article having a base material. A weld filler material is applied to the base material by welding to form a treated article. The weld filler material includes at least one temperature depressant element at a concentration sufficient to form potential eutectic-containing zones in the welded article. The potential eutectic-containing zones contain the at least one temperature depressant element. The welded article is heated to a temperature sufficiently high and for a time sufficiently long to form at least partially liquefied eutectic-containing zones. The at least partially liquefied eutectic zones are capable of flow into cracks formed during the welding.

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.
