The effect of the wa.l thickness of the ca.tings on the microstructure of the formed la.ers wa. studied, a.d two thicknesses, 8 mm a.d 25 mm, were studied. The forma.ion of a.continuous a.d homogeneous rich a.uminum la.er on the surfa.e of the ca.t iron wa. observed. The formed la.er is composed of two successive zones identified a. two proeutectoid pha.es Fea.+Fea./Fea.2 a.d single-pha.e Fea., which significa.tly increa.es the surfa.e ha.dness. Furthermore, this cha.ge in surfa.e composition ma.es it possible to reduce the ma.s of the immersed sa.ples in a.1 M hydrochloric a.id solution during different exposure times(1 to 4 da.s). Consequently, a.clea. improvement in the corrosion resista.ce of the trea.ed la.ers is highlighted.
