The surface defects in the coating influence the corrosion behavior and service lifetime of the EN coating causing easy access to the substrate.(11), (35) Furthermore, since the MoS2 particles have little conductivity (2.09 x [10.sub.-4] [ohm.sub.-1] c[m.sub.-1]), (36) local galvanic cells probably were created on the surface of the coating in which the Mo[S.sub.2] particles act as cathodic sites in contrast with the EN matrix that acts as an anodic site.(34) These local galvanic cells in the EN-Mo[S.sub.2] coating can be another cause for the lower corrosion resistance of this coating in comparison with the EN coating.
