An article comprising a turbine component formed of a nickel-chromium (Ni&#x2014;Cr) alloy including from 2 to 50 wt % chromium balanced by nickel is disclosed. The Ni&#x2014;Cr alloy is thicker than at least 125 &#x3bc;m to make a self-supporting turbine component, and the turbine component includes a rotor blade, a stator, or a vane. The Ni&#x2014;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.

Electroformed nickel-chromium alloy

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.
