Control of electrodeposit properties of nickel and nickel alloy by pulse plating.
… density. Also, the composition and properties of electrodeposited Ni/Fe alloy have been related to the composition of electrolyte and the deposition conditions. Distinct differences between direct and pulsed processes revealed themselves in the surface characteristics, micro-hardness data, cathode …

Electrochemistry of systems containing aluminum phosphate dissolved in fused borate and phosphate mixtures
… have not been used commercially, to any extent. Electrodeposition of aluminum was attempted, most frequently from nonaqueous organic solutions and from fused mixtures. Aluminum halides, especially aluminum chloride, was the solutes most frequently used. It is known that aluminum oxide is peptized …

On the fracture and fatigue crack growth of thin sheets of nanocrystalline metal alloys
… crack growth was investigated in thin sheets of electrodeposited nickel–1.6% cobalt (Ni-Co) and rolled Inconel 718. Digital image correlation (DIC) was used to determine the crack opening displacement profiles, and the entire crack displacement fields. These parameters were then used to determine …
