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 M O , where M is selected from the group comprising Mo, V and W. The heteropolymetalates have the general formula BM O , 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, (PMo O ) , (PMo V O ) , (MnPW O ) , (PW O ) , (SiMo O ) , (SiW O ) , (Mo O ) , (CeMo O ) and mixtures thereof.
