Trivalent chromium conversion (TCC) coating formation on AZ91D magnesium alloy has been investigated using scanning electron microscopy, energy X
Read MoreThe aim of this paper is to model the CFP and simulate the low lying energy levels scheme for trivalent chromium doped BSO crystals and co-doped with phosphorus. The
Read MoreChromium has six oxidation levels; however, only trivalent chromium oxide is extremely stable. It is important to emphasize that trivalent blue chromates usually have a layer thickness of nearly 80 nm, consequently it does not provide as good corrosion protection as the thicker yellow hexavalent chromate (300 nm) [46] .

Read MoreCurrently, the iron chromium redox flow battery (ICRFB) has become a research hotspot in the energy storage field owing to its low cost and easily-scaled-up.
Read MoreElemental chromium has a CAS Registry Number of 7440-47-3. The three most stable forms in which chromium occurs in the environment are the 0 (metal and alloys), +3 (trivalent chromium), and +6 (hexavelent chromium) valence states. In the +3 valence state, the chemistry of chromium is dominated by the formation of stable complexes with

Read MoreIn contrast, chromium obtained from trivalent chromium baths shows an amorphous phase in XRD analysis [32, 33]. This is because carbon doping into the chromium crystal lattice disrupts the ordered arrangement of chromium atoms, leading to the amorphization of chromium coatings [ 34, 35 ].
Read MoreIn this study, we developed and optimized a trivalent chromium coating electrodeposited on 304L stainless steel (SS) from a Cr-trivalent bath. The results reveal that the Cr coatings at all bath temperatures except for 80 °C showed clusters of polyhedral grains, however, the grain sizes decreased with an increase in bath temperature. Also, the coatings deposited
