摘要： An apparatus and process for depositing an overlay weld on a substrate in a manner that reduces dilution of the substrate material. A consumable electrode is positioned in proximity to the surface of the substrate, and an electrical potential is applied between the electrode and substrate to generate an electrical arc therebetween. The arc melts the electrode and forms a molten spray that deposits on the substrate surface. Energy of the electric arc is absorbed to reduce the temperature at the substrate surface by feeding an additional filler material into the electric arc toward its center axis. The filler material continuously melts prior to reaching the center axis of the electric arc, and the electrode and filler materials are simultaneously deposited to form the overlay weld on the substrate. Sufficient energy is absorbed by the filler material to reduce intermixing between the overlay weld and the substrate.

摘要： A method for making an equiaxed investment casting. The method utilizes an ultrasonic generator to send an ultrasonic pulse into molten metal in an investment casting mold. The investment casting mold is positioned within a working zone of furnace having low output induction coils for generating a convection current in molten metal. The ultrasonic pulse separates dendrites growing from the face of the mold inward into the molten metal. Instead, equiaxed grains can nucleate within the molten metal. In addition, the ultrasonic pulse and the low output induction coils circulate the molten metal as solute is rejected from solidifying equiaxed grains. The mixing reduces the effects of segregation in the solidifying alloy and assists in nucleating equiaxed grains.

摘要： 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.
