Electrodeposition and Micro-Mechanical Property Characterization of Nickel–Cobalt Alloys toward Design of MEMS Components

Nickel–cobalt alloys were prepared by alloy electrodeposition with a sulfamate bath, and the mechanical properties on micro-scale evaluated for application as micro-components in miniaturized electronic devices. Nickel bromide commercially available surface brightener used additives. The cobalt content increased from 21.5 to 60.1 at.% after addition of nickel into grain size refined 21.1 13.2 nm when was used. micro-compression test using micro-pillar type specimens fabricated focused ion beam system take sample effect consideration. yield strength nickel–cobalt having an average at 13.9 66.6 reached 2.37 GPa, revealing influences size, boundary strengthening, solid solution strengthening effects.
