Nanocomposite Ni/diamond layers produced by the electrocrystallization method
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 75, Issue 1
Abstract
Purpose: The aim of this paper concerns the manufacturing of nanocomposite Ni/diamondsurface layers deposited on S235JR carbon steel using electrocrystallization method andexaminations of their structures and properties.Design/methodology/approach: The performed research covers Ni/diamond nanocompositelayers and for comparison purposes also nickel layers produced by theelectrocrystallization method. The disperse phase structure and whole produced layerswere characterized by: X-ray diffraction (XRD), scanning electron microscope (SEM), opticalmicroscopy. The realized research was performed to select the features of the producedlayers such as microhardness, tribological properties and corrosion resistance.Findings: The results of completed studies indicate on a compact structure and a goodadhesion of produced layers with the steel substrate. The Ni/diamond nanocompositelayers have a higher hardness and wear resistance, as well as greater corrosion resistancetested in a corrosive environment as compared to Ni nanocrystalline layers.Research limitations/implications: It is reasonable to continue further researchon influences of different amount of nanodiament in nickel matrix and its impact on thetribological, corrosion, and thermal properties so produced nanocomposite layers.
