Abstract
The paper deals with the study of modified phosphate compounds from their anticorrosion action point of view. The pigments start with zinc orthophosphate, the modification of which can give phosphosilicates, phosphomolybdates, or basic phosphates. In the region of cations the combination of zinc with calcium, strontium, barium, or aluminum are possible. The modified anticorrosive pigments differ in water solubility, inhibition efficiency of the aqueous extracts and anticorrosion actions in organic coatings. The various types of modified phosphates were studied. The effect of organic inhibitor in presence of anticorrosive inorganic pigments in coatings was determined.
