“…Figure 3a shows the polarization curves for the Zr substrate, the simple PEO, and the PEO composite coating with Al 2 O 3 , CeO 2 , or ZrO 2 nanoparticles, termed as PA, PC, and PZ, respectively. Besides, the composite coating of ZrO 2 -SiC produced in phosphate electrolyte exhibited superior corrosion resistance compared to coatings produced in aluminate and silicate electrolytes, due to the modified surface morphology of the coating [58].…”

A plasma electrolytic oxidation (PEO) is an electrochemical and eco-friendly process where the surface features of the metal substrate are changed remarkably by electrochemical reactions accompanied by plasma micro-discharges. A stiff, adhesive, and conformal oxide layer on the Zr and Zr-alloy substrates can be formed by applying the PEO process. The review describes recent progress on various applications and functionality of PEO coatings in light of increasing industrial, medical, and optoelectronic demands for the production of advanced coatings. Besides, it explains how the PEO coating can address concerns about employing protective and long-lasting coatings with a remarkable biocompatibility and a broad excitation and absorption range of photoluminescence. A general overview of the process parameters of coatings is provided, accompanied by some information related to the biological conditions, under which, coatings are expected to function. The focus is to explain how the biocompatibility of coatings can be improved by tailoring the coating process. After that, corrosion and wear performance of PEO coatings are described in light of recognizing parameters that lead to the formation of coatings with outstanding performance in extreme loading conditions and corrosive environments. Finally, a future outlook and suggested research areas are outlined. The emerging applications derived from paramount features of the coating are considered in light of practical properties of coatings in areas including biocompatibility and bioactivity, corrosion and wear protection, and photoluminescence of coatings

“…129) PEO coupled with electrophoretic deposition (PEO-EPD) is gaining much attention for producing composite coatings with better properties than PEO. 130 Since the PEO coatings always have a porous structure, as follows from its mechanism, 132) the corrosion resistance and bioactive properties can be further improved by a pore sealing treatments with an organic compound top coating. Superhydrophobic composite PEO-coatings on titanium and magnesium obtained by application of polytetrafluoroethylene (UPTFE) for the PEO coating pore filling reduces the corrosion rate by 4 orders of magnitude and more; this helps to control inflammatory response of a body.…”

Recent years have witnessed a series of numerous investigative activities to improve existing metallic biomaterials (Ti and Ti alloys, stainless steels, Mg and Fe alloys) by their nanostructuring for advanced medical applications using severe plastic deformation (SPD) processing. Nanostructured metals are peculiar for their enhanced strength and fatigue life, which makes them an excellent choice for fabrication of implants with improved design for dentistry and orthopedics. Moreover, surface modification of nanometals by chemical etching and bioactive coatings show a significant improvement of biomedical properties. Various studies conducted in this field make it possible to fabricate miniaturized dental implants and nanoTi plates with enhanced osseointegration.

“…Unlike aluminum and titanium, zirconium alloys are less investigated in terms of the specific features of the PEO process mechanism; however, recent studies appear to be focused on Zr and its alloys [5][6][7]. One important Zr alloy application is nuclear fuel cladding which suffers from hydrogen embrittlement in the boiling water environment of a power plant [8,9]; the PEO coatings show a good promise for fuel cladding corrosion protection [10,11].…”

This paper is devoted to the study of the current density distribution effect on plasma electrolytic oxidation process and resultant coatings on a Zr-1Nb alloy. The influence of the distance between the plates simultaneously placed into an electrolyzer was evaluated to assess the throwing power of the PEO process. The current density on the facing surfaces of the plates decreases when the distance between them shrinks. This current density has a notable impact on the resultant PEO coating in terms of the surface morphology parameters and electrochemically evaluated corrosion resistance. The influence of this effect is low on the stages of anodizing and spark discharges (60–120 s of the PEO), and significantly increases on the stage of microarc discharges (120–360 s of the PEO). The coating obtained with a smaller distance between the plates, while having the same coating thickness as the others, exhibits higher wear resistance. New correlations between the current density, diffusion coefficient, time constant of nucleation and the coating thickness in the middle of the facing samples were established; in addition, a correlation of the coating morphology in this area with the roughness parameters RPc, RSm was shown. This study contributes to the development of optimized PEO processes for the simultaneously coated several devices of complex shape, e.g., orthopedic implants.
