This disclosure relates to compositions for protecting a metallic surface susceptible to corrosion, the composition comprising a first component comprising an aqueous mixture of an acid-phosphate of chemical formula A(HPO).nHO, where A is hydrogen ion, ammonium cation, metal cation, or mixtures thereof where m=1-3, and n=0-6; the first component solution adjusted to a pH of about 2 to about 5, the first component having a particle size distribution between 0.04 to 60 micron; and a second component, configured for combination and at least partial reaction with the first component to provide a phosphate ceramic, the second component comprising an aqueous solution or suspension of an alkaline oxide or alkaline hydroxide represented by BO, B(OH), or mixtures thereof, where B is an element of valency 2(m=1, 1.5, or 2) the second component solution adjusted to a pH of between 9-14.

Inorganic phosphate corrosion resistant coatings

This disclosure relates to method phosphating an iron surface susceptible to corrosion, the method comprising contacting an iron surface with an aqueous mixture of an acidic phosphate component, a basic component, and at least one silicate; and forming a passivation zone chemically bound to the iron surface of one or more iron ions corresponding to the iron surface, the acidic phosphate component, the basic component, and at least one corrosion inhibitor precursor.
