Abstract
This disclosure relates to an inorganic-organic metal phosphate ceramic coating from the reaction of an inorganic phosphate of the formulas (i) Am(H2PO4)m.nH2O or (ii) AH3(PO4)2.nH2O; where A is ammonium or an m-valent metal element; m=1, 2, or 3; and n is 0 to 25; and at least one metal oxide or hydroxide represented by the formula B2mOm or B(OH)2m, where B is a 2m-valent metal; and m=1 or 1.5; thereof; and at least one polymer capable of reacting with at least the one metal oxide or hydroxide; or a first organic precursor combined with the inorganic phosphate and a second organic precursor combined with the at least one metal oxide or hydroxide, the second organic precursor configured to chemically react with the one or more first organic precursor.
Claims8
An article comprising
- an inorganic-organic phosphate composition in direct contact with the article, the inorganic-organic phosphate composition comprising:
- (i) at least one metal phosphate phase comprising one or more reaction products of
- (a) one or more acid-phosphates representative of one or more of formula (i) or (ii):
- (i), Am(H2PO4)m.nH2O;
- or
- (ii) AH3(PO4)2.nH2O;
- where A is ammonium or an m-valent metal element of m=1, 2, or 3;
- and n is 0 to 25;
- and
- (b) one or more bases represented by either or both of the formulas B2mOm or B(OH)2m, where B is a 2m-valent metal where m=1 or 1.5;
- and
- (ii) at least one organic phase layer;
- wherein the at least one metal phosphate phase is substantially between the at least one organic phase layer and the article.
