“…The mechanism of the carbon inclusion in the deposits is still unclear. Some authors believe that it is caused by the formation of Cr(III) complexes with organic ligands [17,18]. In [20], the assumption was made that carbon inclusion in the deposits is due to the surface chemical reaction between Cr(II) species and adsorbed on the electrode organic compounds.…”

“…This is a common fact for coatings deposited from the solutions based on trivalent chromium compounds. It is described in detail in the literature [13][14][15][16][17][18][19][20][21]. The mechanism of the carbon inclusion in the deposits is still unclear.…”

“…The experimental data reported in [13][14][15][16] were obtained for coatings deposited from the aqueous solutions (2 wt% of carbon in [16] is equal to 8.1 at.%). It was suggested [17,18] that the cause of the carbon inclusion in the coatings is the formation of complexes of Cr(III) ions with the anions of organic acids (formate, oxalate, etc) in the solutions applied for electrodeposition [17,18].…”

Cr-C-W coatings were deposited from organoaqueous solutions containing dimethylformamide by electrolysis. The obtained deposits were studied by the modern physical methods: X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), time-of-flight secondary ion mass spectrometry (SIMS), and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The corrosion of Cr-C-W electrolytic deposits was studied in the solutions of sulfuric acid, sodium chloride, and hydrochloric acid. Cr-C-W coatings demonstrated higher corrosion resistance compared with chromium deposits. It was suggested that the decrease of the corrosion rate is caused by the formation of the thin layer enriched with tungsten and its oxides at the surface of the Cr-C-W alloy. This assumption was confirmed by both XPS and SIMS.

“…Research in the past decades has focussed on the development of trivalent chromium electrolytes since Cr(III) compounds are not toxic [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19].…”

“…Obtaining thick chromium coatings from electro lytes based on trivalent chromium compounds is one of the key problems in modern electroplating [1][2][3][4][5][6][7][8][9][10][11]. In recent decades, significant progress has been achieved in this direction which is related both to development of new effective electroplating technolo gies and to a deeper understanding of the kinetics and mechanism of the processes occurring under chro mium plating.…”
