Abstract: A method is provided for improving the corrosion resistance of material substrates. The method is particularly applicable to the protection of metal substrates, such as ferrous metal articles, among other metals, and, in particular, to the protection of low alloy steel gas turbine engine components for aircraft in which the surface is provided with an adherent protective layer of a sacrificial coating rich in magnesium and also containing silicon, oxygen and optionally iron. The coating is characterized by the presence of magnesium silicide as a major active constituent.
