Features chrome plated electrolytes based compounds is trivalent chromium using particle measuring nano-sized zirconium oxide

Spectrophotometrically studied the ionic composition and carried out sedimentation analysis of sulfate-oxalate chromium electrolyte containing nano-sized particles of zirconium oxide. The method of mathematical planning of experiments to optimize the composition of the electrolyte and deposition regimes "trivalent" chromium coatings were calculated regression equation relating the microhardness of coatings and the deposition rate of Cr (III) of process parameters.
