Abstract
The feasibility of modifying iron oxides (α-Fe2O3, γ-Fe2O3, and an oxide covering the surface of carbonyl iron) with various organosilicon and organophosphorous compounds has been studied. It has been shown that the surfaces of these oxides can be successfully modified with ethoxysilanes and diethyl ester of butylphosphonic acid. Resultant grafted layers have being found to be rather hydrolytically and thermally stable. The effect of the modification on the corrosion and erosion stability of carbonyl iron has been investigated. It has been demonstrated that the modifying layers can efficiently protect carbonyl iron particles from corrosion.
