Abstract: An article comprising a turbine component formed of a nickel-chromium (Ni—Cr) alloy including from 2 to 50 wt % chromium balanced by nickel is disclosed. The Ni—Cr alloy is thicker than at least 125 μm to make a self-supporting turbine component, and the turbine component includes a rotor blade, a stator, or a vane. The Ni—Cr alloy is electroformed on a mandrel by providing an external supply of current to an anode and a cathode in a plating bath containing a solvent, a surfactant, and an ionic liquid including choline chloride, nickel chloride, and chromium chloride.

Abstract: A coated metal component includes an aluminum alloy substrate and a protective aluminum coating on a substrate. An interfacial boundary layer between the coating and substrate enhances coating adhesion. The boundary layer includes isolated regions of copper or tin produced by a double zincating process. The protective aluminum coating exhibits improved adhesion and is formed by electrodeposition in an ionic liquid.

Abstract: A method of applying a protective coating with improved adhesion on an aluminum alloy component includes first pretreating the surface of a component by depositing a sacrificial protective immersion layer using a zincating or similar process. Portions of the protective immersion layer as well as portions of the underlying aluminum alloy substrate are then electrolytically etched off in an ionic liquid. A protective aluminum coating is then electrodeposited on the component in an ionic liquid

Abstract: Various implementations described herein are directed to a method of performing a land seismic survey operation. The method may include receiving a first information from a central recording system by a computer system on a seismic truck. The first information describes time and locations of seismic shots being performed in the seismic survey operation. The method may include using a set of rules and the first information to determine a start time for a seismic shot at a next shot location. The method may also include transmitting a second information that describes the next shot location and the start time to the central recording system.
