    Abstract: To prove whether phase formation in an electrochemically deposited metal indeed passes a liquid state stage, experiments involving application of an external force during electrodeposition were carried out and structural features of deposit were subsequently determined. Following experimental facts in support of the phenomenon in point were observe... Show More

    Abstract: Characterisation of Sn-Ni-Fe ternary alloy deposits obtained by pulse electrodeposition show that novel alloys of varying composition can be successfully deposited exhibiting amorphous structures using specific on/off pulse plating parameters for electrodeposition in combination with an electrolyte based on gluconate as a complexing agent. The depo... Show More

    Abstract: The electrodeposition of Ni-Zn alloy coatings having high nickel content (74-97 wt%) from a sulfamate bath was studied. The investigation was performed by means of cyclic voltammetry, potentiostatic electrodeposition, X-ray diffraction, scanning electron microscopy and energy dispersive X-ray analysis. The effect of the experimental parameters (dep... Show More
