Methods for treating a ferrous metal substrate |
| abstract |
A method of treating a ferrous metal substrate, comprising: (I) contacting the ferrous metal substrate with an aqueous pretreatment composition having a pH of from 4 to 5.5 and comprising: (a) a compound of group IIIB and/or IVB metal; (b) phosphate ions; and (c) water, wherein the phosphate ions are maintained in a bath of the pretreatment composition in an amount: (i) resulting in a weight ratio of phosphate ions to ferric ions of from 1 to 1.7 :one; and (ii) resulting in a weight ratio of Group IIIB and/or IVB metal to phosphate ions of at least 2:1. |
