Abstract

Metals, such as aluminum, steel, copper, and silicon iron, can be protected against both environmental exposure and abrasion by first coating the metal with a corrosion inhibiting layer followed by a protective moisture barrier organic coating.

Protective Coating Process for Silicon Iron

Metals, such as aluminum, steel, copper, and silicon iron, can be protected against both environmental exposure and abrasion by first coating the metal with a corrosion inhibiting layer followed by a protective moisture barrier organic coating.

An example of such a protective coating procedure is as follows. The surface of a metal part, such as a silicon iron motor stator, is abraded to provide a fresh surface. The exposed metal surface then is decreased with a chlorofloroethane/isopropyl alcohol solution. The part is force dried for ten minutes at 125 degrees F for 30 minutes at room temperature. Now, a uniform coating of IRILAC* 1000 is applied to the cleaned surface of the part, one part IRILAC 1000 concentrate and two parts of distilled water.

The coating of IRILAC 1000 is cured by heating the part for 60 minutes at 160 degrees F and the part is cooled back to room temperature. A uniform coating of epoxy-polyamide is applied on the IRILAC 1000 coating. This epoxy overcoating is cured for 16 hours at room temperature followed by 1 1/2 hours at 135 degrees F. *Trademark of Allied Research Products.
