Abstract: | In the work it is shown that addition of individual pure detonation synthesis nanodiamonds to nickel- and iron-plating electrolytes results in an increase in microhardness (2–3.5 times) and wear-resistance (3–6 times) and a decrease in porosity (3–4 times) of a coating. The use of nanodiamonds as a component of diamond-containing blend (a semi-product of synthesis of the nanodiamonds) results in deterioration of all of the above properties for a nickel–diamond coating and great improvement of the same properties for an iron–diamond coating. |
