Studies on the corrosion characteristics of friction stir welded AZ61A magnesium alloy welds under immersion tests and potentiodynamic polarisation tests: a comparative evaluation

Investigation of graphene-reinforced magnesium metal matrix composites processed through a solvent-based powder metallurgy route

“…The values indicate that the OCP of AZ31 alloy becomes negative (−1.53 V) as compared with that of the composite material. However, the standard potential of the Mg electrode is 2.37 V, but measurement of their OCP as −1.53 V indicates the formation of Mg(OH) 2 [23]. Increasing the value of OCP shows the presence of the used metals for not as much of dissolving nature in the electrolyte.…”

Impact of nano‐SiCP and nano‐hBNP on the corrosion performance and fatigue behavior of Mg–Zn hybrid nanocomposites

“…The sample's initial weight ( W 0 ) was determined, and it was subsequently sprinkled with a NaCl solution for 72 h. The corrosion outcomes of the specimens are eliminated as it is soaked in a mixture comprising 50 g of chromium trioxide (CrO 3 ), 2.5 g of silver nitrate (AgNO 3 ), and 5 g of barium nitrate (Ba(NO 3 ) 2 ) in 250 ml of distillate water for 1 min. [ 43 ] The specimens were weighed again after being cleansed with distillate water and dehydrated ( W 1 ). Weight loss ( W ) may be calculated using the below equation: $$$W={W}_{0}-{W}_{1},$$$where W represents the weight reduction in grams, W 0 is the initial weight before the test, and W 1 is the weight later to the test.…”
