Microstructure and thermal stability of nickel layers electrodeposited from an additive-free sulphamate-based electrolyte

The influences of the current density and the temperature on the microstructure and hardness of Ni layers electrodeposited from an additive-free sulphamate bath were investigated. The microstructure and thermal stability of the electrodeposits was investigated with a combination of transmission and scanning electron microscopy and X-ray diffraction; the Vickers microhardness was measured in cross-sections. The present article is meant as a reference for forthcoming articles on the investigation of various strengthening mechanisms on the microstructure, hardness and thermal stability of Ni (alloy) electrodeposits.
