摘要： A system and method for producing a rigid, heat-resistant part, such as a superalloy, via electrodeposition. The method can include the steps of coating a secondary alloy particulate with a superior alloy, forming a pre-coated particulate, dispensing a quantity of the pre-coated particulate into a container of an electrolytic solution, and applying a charge to the electrolytic solution such that the pre-coated particulate is electrodeposited onto a cathode or an external casing of the cathode. The pre-coated particulate can include particulate of non-uniform size and/or shape. The secondary alloy particulate is protected in the catalytic solution by the superior alloy coated thereon, such as nickel, iron, cobalt, and/or copper. The method also includes a step of vibrating or agitating the electrolytic solution before and/or during applying the charge to the electrolytic solution for even distribution of the pre-coated particulate onto the cathode or an external casing thereof.

摘要： A method of bonding two or more metallic components into a single piece. The bonding surfaces of the metallic components are protected from reaction with the environment. A force is applied to the metallic components to push the bonding surfaces together. Simultaneous with applying the force, an electric current is passed through the bonding surfaces to joule heat and weld the bonding surfaces together to form the single piece. The bonding surfaces may be protected by plating with a noble metal, applying a coating, shielding with a noble gas, or placing into a vacuum. A press may be used to apply the force. The force and the electric current may be sufficient to push out metal around the joint of the bonding surfaces, and at least one of the bonding surfaces may be drafted to facilitate pushing out the metal. The electric current may be pulsed to induce electroplasticity.
