The present invention relates to a process for treating a brass-plated steel wire comprising applying to the wire an aqueous zinc phosphate solution having a pH of from about 1.5 to about 5.0 and containing (1) a total of from about 10 to about 70 grams per liter of phosphoric acid, (2) from about 4 to about 25 grams per liter of free phosphoric acid, (3) from about 2 to about 25 grams per liter of Zn+2 which may be derived from the group consisting of zinc oxide, zinc phosphate or mixtures thereof, and (4) wherein the mole ratio of total phosphoric acid to free phosphoric acid ranges from 1:1 to 8:1. In accordance with the present invention, the zinc phosphate coating on the brass-plated steel cord inhibits corrosion and adhesion of the wire to rubber after vulcanization is improved.
