Method for Producing Magnetic Coating on Stainless Steel

The method directly electroplates stainless steel with a strongly adherent magnetic coating from a bath having a low pH value.

Coatings of cobalt and cobalt nickel alloys are electroplated on stainless steel from a hydrochloric acid bath. The cobalt and nickel are present in the bath in the form of nickel chloride and cobaltous chloride. A wide range of magnetic properties is obtainable by varying the cobaltous to nickel ion ratio. Permissible coating thicknesses up to 75 micro-inches are also obtainable.
