Abstract

Corrosion-resistant, paint-holding coatings are formed on metallic surfaces by treating them with a hot aqueous solution containing a dihydrogen phosphate, an oxidizing agent, a fluoborate and boric acid, the solution being replenished by the addition of a simple fluoride and sufficient boric acid to keep the boric acid content of the solution within desired limits. The fluoborate and boric acid may be introduced into the initial coating solution as such, or as a simple fluoride and sufficient boric acid to convert the fluoride into fluoborate, and to provide the desired free boric acid content; the phosphate may be zinc dihydrogen phosphate; and the oxidizing agent is preferably a nitrate although nitrites, iodates, periodates, peroxides, bromates, quinones, chlorates, perchlorates, sulphites and permanganates may be used. The fluoride may be sodium fluoride or sodium bifluoride. Specification 655,079 is referred to.
