PROCESS OF PHOSPHATING AN IRON SUBSTRATE Abstract of the Disclosure The specification discloses a process for iron phosphating the surface of an iron substrate in which the surface is treated with a phosphating solution comprising at least one alkali metal or ammonium phosphate and at least one aromatic nitro compound as a phosphating accelerator in an aqueous medium having a pH of about 3 to 6.5 in a closed system phosphating installation. By employing this process, the usual build-up of contaminating ions can be avoided so that a satisfactory phosphate coating can be obtained even after a long period of use of the phosphating solution.
