aspects of the use of CORROSION INHIBITORS IN WATER SYSTEMS

It would be difficult to give a precise definition of an inhibitor, but broadly speaking, its effect in most cases is to interpose a barrier between a metal and an aggressive environment. Desirable characteristics are that the barrier formed should be thin, so that heat conductivity is not appreciably affected; that it be reasonably stable to mechanical and thermal stress; and that it can be quickly repaired by the reserve or excess which is in solution.
