Avoided is at a higher voltage than cathode during corrosion In a concentration

Question

Avoided is at a higher voltage than cathode during corrosion In a concentration cell the metal in contact with higher ionic concentration electrolyte corrected with the same metal in contact with the lower ionic concentration electrolyte Austenite to marten site transformation is responsible for the shape memory effect in In a corrosion cell, corrosion occurs only at the anode. During corrosion current flows from cathode to the anode. A 2-mm long crack on the surface is more likely to cause failure as compared with a 3 the same geometry present in the interior of a component during tensile loading. Inter-lamellar (alpha-beta interpolate) spacing will be larger in faster cooled eutectic alloy Many large-size grains of pearlier from in 0.7%C steel when it is cooled rapidly from temperature, as compared with one which is cooled slowly.
