Properties of a phosphate coating are improved by preparing and applying a mixture containing nano-dimensioned hexagonal boron nitride, known as a solid lubricant, to a Zn, Zn-Ca, Fe and Mn phosphate coating. The hexagonal boron nitride is added to the coating bath during the phosphate treatment. Products coated with Zn, Zn-Ca, Fe and Mn phosphate accommodated with hexagonal boron nitride are disclosed. |
