basic fluxingNi-base superalloys1173Kcorrosion behaviorIN-738LCIN-939The influence of the electrode potential on the corrosion behavior of a series of Ni-base superalloys has been investigated in a (mole %) 90Na 2SO 4-10K 2SO 4 melt at 1173K. Acidic fluxing occurs at positive potentials ...
2Na + ½ O2→ Na2O (strongly basic) (3) Na2O (base) + SO3 (acid) → Na2SO4 (salt) (4) Na2O (base) + V2O5 (acid) → 2NaVO3 (salt) (5) Vanadium pentoxide (V2O5), a potent acidic oxide with a melting point of 690 °C, and sodium metavanadate (NaVO3), a ...
resulting in decrease in crop productivity and quality1. The excess accumulation of soluble salts in the soil surface is referred to as salinization, which has an adverse impact on agricultural production, biodiversity and sustainable development and may results into delay of onset, reduce ...
