Synthesis, Characterization and Optimization of Electrophoretic Deposition (EPD) Parameters of YSZ Layer on Ti-6Al-4V Alloy substrate: A Recent Study

The goal of this work is to investigate the effect of electrophoretic deposition (EPD) parameters (voltage, time, and concentration) on the thickness, porosity, and coating characterizations of a YSZ layer on a Ti-6Al-4V alloy substrate using DC current. The Taguchi approach was used to identify the best conditions for EPD, and various criteria were used to deposit biochemical coatings. To improve the quality of the alloy surface and meet the requirements of biological orthopaedic application activity, Yttria stabilised zirconia powder (YSZ) was electrophoretically deposited on Ti-6Al-4V alloy substrate using ethanol as a solvent under DC. To precipitate chitosan and YSZ on the alloy substrate, ethanol has been used as a solvent. This electrode-enabled cathodic deposition for characterization has described the surface composition and cross section of coatings. Many tests and inspections were performed, including zeta potential, water contact angle, XRD, SEM, and optical microscopes, to characterise the surface morphology of the YSZ layer. The best conditions for YSZ layer deposition were 40 volts, 2 minutes, and 1 g / l suspension at room temperature. Coating contact angles were varied between hydrophilic 67.489 C and 35.914 C. Appropriate percentages of porosity were obtained with pores ranging in size from 56.601 to 83.505 m.
