|Title:||Empirical optimization of corrosion rate for magnesium-chromium composites|
Chauhan, Nathi Ram
|Abstract:||In this study, optimization of the corrosion rate (CR) of Mg-composites has been evaluated by varying the concentration, reinforcement percentage, and immersion time. As prime material, pure Mg is preferred for this research and chromium (Cr) consider as a reinforcing material with different percentages. CR (miles/yr) has been optimized by varying parameters such as reinforcement percentage as 3%, 5% and 7% including NaCl immersion medium (%) as 2.4%, 3.5% and 4.7% with immersion time (h) such as 48h, 72h and 96h. By using, DOF, minimal CR has been measured with the assistance of Minitab Software having ANOVA and Taguchi approaches. Optimized results reveal that the percentage of corrosion solution is influenced upto 66.10%, reinforcement percentage contributed to 27.56% and immersion time influenced upto 2.81%. An optimized combination of CR is 7wt. % Cr with 2.4% NaCl for 96h. However, microscopy results illustrate shallow crack boundaries in Mg/Cr composites due to its chemical reaction in alkaline solution.|
