Electro-deposited Nickel-Cobalt Alloy

Abstract: 
The increase in tensile strength for this Marshall Space Flight Center's technology is directly proportionate to the concentration of co-deposited cobalt; lower levels result in an alloy that is more malleable and can be used for structural applications, while too much cobalt makes the coating brittle. Developed in response to a specific technology needed by NASAs Space Shuttle program, the method does not require the use of any organic additives beyond those used in traditional nickel sulfamate plating baths. The technology also encompasses an in-situ monitoring system that periodically checks for the tensile strength and purity content of the deposit. This method and monitoring system can be used with any electrolytic plating process that requires a knowledge of deposit mechanical properties and/or chemical composition.
