“…The binary Co-W and ternary Co-W-Fe coatings were obtained under galvanostatic mode at temperature 80 °C from the gluconate-chloride electrolytes [20]. It is shown that the Co-W alloys successfully compete with galvanic chromium on wear and corrosion resistance.…”

“…Further attempts were made in recent years to produce coatings of metal alloys, such as Co-W, Ni-W, Fe-Cr, Cr-Ni, Fe-Cr-Ni and Cr-Co. These new compositions, which were shown to exhibit relatively high hardness (<800 VHN), were fabricated in order to replace the hexavalent chromium (Cr(VI)) electroplating process [5][6][7] . A limited amount of work has been carried out to date in the fi eld of chromium composite coatings [ 8 ] .…”

Metallic fi lms impregnated with fullerene-like-WS 2 (MoS 2 ) nanoparticles were fabricated on stainless steel and Ti-Ni substrates using galvanic and electroless deposition. The coatings were obtained from aqueous suspensions containing the metallic salts as well as the dispersed nanoparticles. Tribological tests showed that the fi lms have low friction and wear. Such coatings could be useful for numerous civilian and defense-related applications.

“…Electrolytic chromium is most popular for such purposes and is used to increase the wear resistance of materials, but the process of producing such coatings is environmentally harmful. Coatings made of electrolytic chromium meet many performance requirements [1][2][3], so different nickel [6], iron-cobalt [7], cobalttin [8,9], and ternary [10][11][12][13] alloys were studied as its potential replacements [3][4][5]. The results are summarized, for example, in [4].…”

UDC 621.762 The tribological and corrosive characteristics of binary and ternary alloys electrodeposited from CoW, FeW, CoMoP, and CoWP citrate solutions are studied. The tungsten content of CoW alloys reaches 31 at.% and of FeW alloys 34 at.%. The introduction of phosphorus into the alloys reduces the content of tungsten from 26.7 to 19.7 at.% (at 4.5 at.% P). The molybdenum content of CoMoP alloys is 0.7-1.0 at.% at 5 to 8 at.% P. The electrolytic tungsten alloys are nanocrystalline and subgrains are 4 to 7 nm in size. The nanohardness of tungsten-rich alloys (∼13 GPa) is comparable with that of electrolytic chromium coatings. The wear resistance of the deposited alloys is quite high and is commensurable with that of hard coatings such as TiB 2 , TiN, and TiAlN. The tribooxidation of FeW alloys in dry friction is revealed. The corrosion resistance of the coatings is similar to that for electrolytic chromium.
