Electrodeposition of Ni-ZrO2 Nanocomposites from Methanesulfonate Electrolytes

摘要

We study the colloid-chemical properties of methanesulfonate electrolytes used for the electrodeposition of Ni-ZrO2 nanocomposites. We observed higher aggregate stability of the dispersed phase as compared with sulfate electrolytes. This results in smaller sizes of the agglomerates of zirconium dioxide in the solution. It is shown that the mass content of the inert phase in the coating obtained from the methanesulfonate electrolyte is elevated and that the microhardness of these deposits is higher than the microhardness of the coatings electrodeposited from sulfate electrolytes.
