As we know we use the paint mainly to protect the metal from corrosion.
Paints protect the metal in different ways. Some of the just shield the metal from environment, Some by inhibiting the funtion of galvanic cell, which is required for coorosion.
like red lead which is known to be an anode inhibitor.
I will be happy to help me out.
I need the principle how and inhibiting paint work.

It is based on electrochemical principles. They divert the electron flow thereby preventing corrosion of the base surface.

There are many reasons for corrosion. stress on metal and welding areas are suppose to be more coreded that other areas , different if properties of metal causing a cilvanic cell which causes corrosion, painting the metal with lead red or and any other paint , prevent corrosion by making the sufrace as one surface in all condentions which prevernt electical cell to form in addition to caoating of the paint wich prevent inviromental effects .
