4(a)
Identify the type of corrosion for the following cases:
i) Formation of cavities of small anodic area around which metal is relatively unattacked as compared large cathodic area.
ii) Simultaneous effect of environment and cylic fluctuation of stress.
iii) The grain boundary phase or a region adjacent to the grain boundary phase or a region adjacent to the grain boundary becomes anodic and get preferably corroded due to precipitation of some phase.
iv) An accelerated attack at the junction of two metals exposed to a corrosive environment.
