“…This mechanism suggests that the complexing ligand is released from the complex, but other studies show that the deposit also contains a significant amount of Cr-carbide, where the carbide is originating from the organic complexing agent [10][11][12][13].…”

“…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].…”

“…In recent years, a number of publications were devoted to Cr-C electrodeposition from Cr(III) baths [1][2][3][4][5][6][7][8][9][10][11]. Such chromium-carbon coatings were shown to distinguish by their valuable physicochemical and mechanical properties.…”

Effect of pulsed electrodepostion on the nanocrystal size, composition, hardness, coefficient of friction and wear resistance was investigated for the Cr-C electrodeposits obtained from a trivalent chromium bath. The electrodeposits were shown to contain about 9% of carbon. Pulsed electrodeposition does not virtually affect the carbon content. At the same time, an increase in the off time duration leads to a decrease in the nanocrystals size. The hardness and wear parameters of the electrodeposits may be sufficiently improved when using pulsed current. For instance, at t on = t off = 1 s, the hardness reaches the values of~1200 ÷ 1300 HV (meanwhile, it is close to 850 ÷ 950 HV at a steady-state electrolysis).

“…It is known that dissolution-reprecipitation is involved in the mechanism of forming core-rim structures [7,8] . Recently, the metal-coated ceramic, coreshell structural composite have attracted great attention because they potentially combine the characteristics of metals and ceramic matrix with improved mechanical properties [9][10][11] . Despite the difference in the preparation, the core-rim of Ti(CN)-based cermets and the metal coated, core-shell have similar structure.…”

The precursor with TiC 0.7 N 0.3 @WO 3 -MO 3 microspheres were prepared by a novel method from the WO 3 -MoO 3 sol dipping. Subsequently, TiC 0.7 N 0.3 @WC-MoC 2 core-shell structural microspheres were successfully obtained by carburizing the precursor at 900 °C in a fl owing mixture of CH 4 (20 ml min -1 ) and H 2 (200 ml min -1 ) for 2 h. Then TiC 0.7 N 0.3 @WC-MoC 2 -15Co cermets were prepared utilizing the core-shell powders by spark plasma sintering (SPS). Powders of the precursors with TiC 0.7 N 0.3 @WO 3 -MO 3 microspheres, TiC 0.7 N 0.3 @WC-MoC 2 microspheres and TiC 0.7 N 0.3 @WC-MoC 2 -15Co cermets were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The obtained TiC 0.7 N 0.3 @WC-MoC 2 microspheres have a dense WC-MoC 2 coatings shell. The thickness of the shell could be easily controlled by adjusting the number of sol dipping cycles. It was found that the TiC0.7N 0.3 @WC-MoC 2 microspheres were more benefi cial to fabricate the "core-rim" structures by SPS.
