Solute and grain boundary strengthening effects in nanostructured Ni-Co alloys

Nanostructured Nickel and Nickel-Cobalt coatings across the Co composition range of 0–83 wt% were synthesized by electrodeposition. Surface morphology, microstructure, and phase formation were investigated in conjunction with alloying level using scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and Rietveld refinement. Fine surface morphologies with average roughness of 6–20 nm and estimated grain sizes of 4–30...
