“One of the greatest metaphorical candle problems of the modern economy is cadmium plating,” he writes. “Cadmium has some unique physical properties that make it especially useful as a plating to protect precision-machined parts from corrosion. Once a machined part is expertly coated in cadmium, that part resists corrosion, is highly solderable and compatible with other metals, and requires little lubrication.”
However, he adds, “cadmium is also an extremely toxic compound, comparable to nuclear weapons in its capacity to poison people and render the environment uninhabitable. Over the past decade, numerous attempts by federal regulators to remove hazardous materials from the environment have targeted cadmium. Executive orders regulating its use have been enacted and revoked, and the Environmental Protection Agency and the Occupational Safety and Health Administration monitor its toxic and carcinogenic impacts on people, water, and soil.”

Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
