| Abstract Scope |
Plasma electrolytic oxidation (PEO) is an electrochemical surface treatment that results in a natural ceramic-like coating. Features such as thickness, porosity, and composition can be controlled by changing the working parameters of the system. By applying this method certain properties of the metal substrate can be improved, including corrosion and wear resistance, and biocompatibility. This study aims to determine if the composition (Zn-3Mg, Zn-10Mg, and Zn-30Mg) in hybrid samples that have previously been processed through high-pressure torsion, alters the effectiveness of PEO. Various materials characterization factors will be considered, including wettability and surface energy, corrosion resistance by immersion and electrochemical testing, and biocompatibility. Using these factors, the resultant PEO coating will be analyzed and optimized through changing various parameters, including the electrolyte, voltage, current, and the duration of the process. The end goal is to achieve a suitable product to be implemented as a biodegradable orthopedic implant. |
