Corrosion of Magnetic and Magneto-Optic Devices

Magneto-optic devices use very reactive alloys for the recording media. Exposure of magneto-optic films to aqueous solutions or high humidity results in pitting, even 

Mitigation of corrosion of electronics equipment by encapsulating the components in plastics has been done. It should be noted that polymers are permeable to moisture. Hermetically sealed ceramic packaging is more successful care must be taken to prevent moisture and other contaminants from being sealed in. A common useful approach for mitigating corrosion of circuits housed in large chassis consists of using volatile corrosion inhibitors. This will require periodic replacement of the carrier.
