Abstract:Electrical conductive Al-rich epoxy resin based paint with an acceptable surface was for the first time prepared on an arc-sprayed aluminium coating surface successfully. Adhesion test and salt solution immersion test (SSIT) with complementary measurements including electron probe microanalysis (EPMA) and Raman spectroscopy were employed. Adhesion properties of the epoxy resin pigmented with Al particles did not degrade. Besides, because of the close Al particle-resin integration and the tight adhesion in the paint-coating interface, the strong adherence of corrosion products on Al particles, as well as probable passivation of Al particles, the paint showed no worse corrosion resistance properties than the epoxy resin and corroded at a similar rate to the epoxy resin, uniformly, slowly and slightly, protecting the coating base as a barrier type film.
