| Abstract: | This work-study the hydrogen evolution rate and inhibitive properties of potassium sorbate, as an antimicrobial and food preservative substance, on the corrosion performance of biodegradable AZ91E magnesium alloy utilized as staples in Sleeve Gastrectomy surgery. This substance used for the first time to protect the alloy from the fast surface degradation process when surrounded by simulated peritoneal fluid (SPF) as a corrosive environment in the stomach. Theoretical quantum calculations were utilized to ensure the inhibition effect of potassium sorbate for the tested alloy as a staple. The corrosion resistance was assessed via electrochemical measurements. The degradation and hydrogen evolution rate is found to be significantly reduced with increasing potassium sorbate concentration. The outcomes displayed that the higher concentration of potassium sorbate (10−3 M) is the most effective corrosion resistant one with inhibition efficiency reaches 99.6% which is mainly ascribed to the creation of a thin protective film of Mg-sorbate. The results were confirmed with a scanning electron microscope (SEM) images. A cell viability test for the alloy was done using MTT assay which clarifies that the alloy immersed in the higher potassium sorbate concentration have higher cell viability and proliferation. |
