ABSTRACT:
The present invention provides a conversion coating solution containing polymetalates and/or heteropolymetalates to oxidize the surface of various metal substrates. The polymetalates have the general formula MxOyn−, where M is selected from the group comprising Mo, V and W. The heteropolymetalates have the general formula BMxOyn−, where B is a heteroatom selected from P, Si, Ce, Mn or Co, and M is again selected from Mo, V, W or combinations thereof. The concentration of polymetalates and/or heteropolymetalates anions is preferably between about 1% and about 5% by weight. Examples of typical anions used include, but are not limited to, (PMo12O40)3−, (PMo10V2O40)5−, (MnPW11O39)5−, (PW12O40)3−, (SiMo12O40)4−, (SiW12O40)4−, (Mo7O24)6−, (CeMo12O42)8−and mixtures thereof.
