Corrosion and wear behaviour of nickel dispersion coatings with nano particles

The present study describes the results of the electrochemical deposition of Nickel dispersion coatings from a Watts electrolyte with nano-scaled particles. Subsequently, the incorporated particles lead to different microstructures and have impact on the mechanical properties. The corrosion and wear behaviour of these layers are of high interest regarding their applications. By means of potentio-dynamic measurements and optical characterisation, the corrosion behaviour can by evaluated in correlation to the applied particles and additives. Unfortunately, an improvement of corrosion protection could not be measured. From investigations by means of oscillation tribometer, it can be shown that the incorporated particles improve the wear behaviour.
