Characterization of carbon nanopowder coating with peek substrate on magnesium alloy (AZ31B)

Alloy AZ31 Mg exhibits great potential as an implant metallic material for restoring human body hard tissues. Yet, it is prone to deterioration in physiological fluid environments. Enhancing the ability of magnesium alloys to resist corrosion and last longer can be efficiently achieved through the application of a nano-material coating. This investigation involved coating the magnesium alloy AZ31 with carbon nanopowder and Poly-Ether-Ether-Ketone (PEEK). This analysis employs Box-Behnken experimental designs to model the response surface. Further, scanning electron microscopy, and electrochemical corrosion testing are performed. In addition, the regression and reliability analysis are executed. The histogram studies are employed to represent the descriptive variables. The test findings indicate that incorporating carbon nanopowder and PEEK into the magnesium alloy can enhance its corrosion resistance.
