ABSTRACT:
A water-soluble composition of matter free of an added buffering agent, for electrolytically depositing a chromium oxide coating on a metal substrate is disclosed comprising a mixture of a complexing agent for a buffering agent such as a boron oxide complexing agent that might be introduced into the composition, a trivalent chromium compound, a weak chelating agent, an optional conductivity enhancing cation, an optional depolarizer, and an optional surfactant. A process is also described as well as a product obtained by the process.
