Nickel surface layers were produced by the method of electro-chemical reduction, using a basic bath of the Watts type and a basic bath modified with D1 organic substances. The process was carried out at a constant cathodic current density equal to 3A/dm². The effect of the organic component on the topography, structure and morphology of the layers was determined. Examinations of corrosion resistance of produced layers were carried out. It has been found that by using the Watts bath modified with an organic additive, we can reduce the surface roughness of the electro-plated nickel layers, refine their structure for nanometric scale of grain size and change the shape of their grain boundaries. It was determined that the nanocrystalline nickel layers exhibit smaller corrosive resistance than the nickel layers about the microcrystalline structure.
