Abstract
Abstract WHEREIN M is a cation having a valence of 1-2; k is an integer 1-2 corresponding to the valence of M; and R is hydrogen or a monovalent aliphatic group of 1-16 carbon atoms; and 3. AN HYDROXY CARBOXYLATE COMPLEXING COMPOUND OR A POLYOL COMPLEXING COMPOUND SELECTED FROM THE GROUP CONSISTING OF MANNITOL, SORBITOL AND DULCITOL; AND 4. AN IODIDE OF A BATH COMPATIBLE CATION OR A COMPOUND PROVIDING AN IODIDE ANION WHEN PLATING COBALT-CONTAINING ALLOYS; FOR A TIME PERIOD SUFFICIENT TO FORM A SOUND METAL ELECTROPLATE UPON SAID CATHODE SURFACE. In accordance with certain of its aspects, this invention relates to a process for the preparation of an electrodeposit which contains iron and at least one metal selected from the group consisting of nickel and cobalt which comprises passing current from an anode to a cathode through an aqueous plating solution containing an iron compound and at least one member selected from the group consisting of cobalt compounds and nickel compounds providing cobalt or nickel ions for electrodepositing alloys of iron with cobalt and/or nickel and containing in combination an effective amount of: 1. AT LEAST ONE MEMBER SELECTED FROM THE GROUP OF COOPERATING ADDITIVES CONSISTING OF: A. PRIMARY BRIGHTENER B. SECONDARY BRIGHTENER C. SECONDARY AUXILIARY BRIGHTENER D. ANTI-PITTING AGENT; AND 2.
