Plasma-electrolytic oxidation of valve metals in Zr(IV)-containing electrolytes

Structure and corrosion resistance of ZrO2 ceramic coatings on AZ91D Mg alloys by plasma electrolytic oxidation

“…et al for the first time reported the preparation of ZrO 2 coatings on Al alloys in K 2 ZrF 6 solution in 1996 [17][18][19][20][21]. Except adding dispersed ZrO 2 or Zr(OH) 4 particles in the other electrolytes [22][23][24] or adopting Zr(SO 4 ) 2 electrolyte directly [19], fluorozirconate electrolyte is the most often adopted one to prepare ZrO 2 ceramic coating up to now [25][26][27][28][29].…”

Silicate-based Plasma Electrolytic Oxidation (PEO) coatings with incorporated CeO2 particles on AM50 magnesium alloy

“…ACCEPTED MANUSCRIPT 16 influence of the particle size; it is has been reported that smaller CeO 2 particles showed higher dissolution rate [56]. Therefore, the incorporation of Ce compounds into PEO coatings via electrolyte with micron CeO 2 particles does not provide good inhibition properties.…”

“…Recent developments on this area are focusing on the use of additives, fluorozirconate-based electrolytes and addition of particles [16][17][18]. The incorporation of ceramic particles from the electrolyte into the PEO coating is a promising but less studied field and most of the available research work has been performed on aluminum alloys [19][20][21].…”
