“…Further, as observed from the XRD results, the prepared ZrO 2 /TiO 2 has shown increased peak intensity with high crystalline phases of rutile TiO 2 and t-ZrO 2 when compared with SiO 2 /TiO 2 and SiO 2 /ZrO 2 composite powders where it exhibits amorphous nature due to the presence of silica. The presence of silica in both the composites leads to less protective nature which might be due to the existence of amorphous nature of SiO 2 and this behavior was further confirmed by Madrama et al [25].…”

Synthesized composite powders (ZrO 2 /TiO 2 , SiO 2 /TiO 2 , and SiO 2 /ZrO 2) were successfully deposited on Ti-6Al-4V by electrophoretic deposition method (EPD) to improve its electrochemical characteristics for better biomedical applications. In the present investigation, the three composite powders were prepared by sol-gel synthesis and its phase purity was analyzed by Powder X-ray diffraction (XRD) method. Further, the performance of the deposited coatings was assessed by scanning electron microscopy (SEM) coupled with energy dispersive X-ray analysis (EDAX), scratch resistance test. The electrochemical properties of the composite coatings were analyzed by Potentiodynamic (Tafel) polarization and electrochemical impedance spectroscopy (EIS) studies. From the results, we observed that the corrosion resistance behavior of the different composite coated metallic substrate exhibited divergent corrosion resistance nature than blank Ti-6Al-4V. Of all these coatings on Ti-6Al-4V, the composite made up of, ZrO 2 /TiO 2 has pronounced corrosion resistance behavior in Ringer's solution when compared to others. This behavior is due to the presence of strong adherent coating owing to the existence of uniform deposition on Ti-6Al-4V.

“…However, their exposure to heat treatment conditions makes them brittle and thus rendering the coatings unfit for wear applications. The hardness of the alloy has also been reported to rise with increasing phosphorus content of up to 8 wt.% and decreases beyond that [51]. The incorporation of nano-carbon was reported to induce a positive potential shift of 60 mV to the Ni-P matrix by ref.…”

The inclusion of second-phase particles in nickel-based matrix to fabricate composite coatings presents a promising solution to combating corrosion and wear deterioration of materials during service. Composite coatings possess better surface properties such as wear resistance, high microhardness, thermal stability, and corrosion resistance than the traditional nickel coatings. Their excellent properties enable them to be used in advanced industrial applications where they will be constantly exposed to severe and degrading environments. There are various surface modification techniques that are employed to produce these coatings and electrodeposition has received wide range of use in fabrication of nickel matrix composites. This technique is associated with low cost, simplicity of operation, versatility, high production rates, and few size and shape limitations. To produce advanced electrodeposits with better performance during application, the optimization and further developments of the process remain vital. Therefore, this chapter aims to review the electrofabrication and properties of nickel composite/nanocomposite coatings for corrosion and wear applications.
