This allows for proper functioning during corrosive exposure of moving parts, threaded assemblies, valves, and delicate mechanisms without jamming with debris. Cadmium shall be deposited directly on the basis metal part without an undercoat of another metal except when the part is either stainless steel or aluminum and its alloys.

Cadmium Platings

Unlike zinc, cadmium does not build up voluminous corrosion products on the surface. Undercutting of threads on fastener parts is not necessary as the cadmium coating has a low coefficient of friction that reduces the tightening torque required and allows repetitive dismantling.

Asm coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution. Corrosion products formed on cadmium are tightly adherent. The as deposited coating Type I is useful for the lowest cost protection in a mild or noncorrosive environment where early formation of white corrosion products is not detrimental or harmful to the function of a component.

ASTM B – 86() – Standard Specification for Electrodeposited Coatings of Cadmium

Undercutting of threads on fastener parts is not necessary as the cadmium coating has a low coefficient of friction that reduces the tightening torque required and allows repetitive dismantling. The lubricity of cadmium plating is used on springs for doors and latches and for weaving machinery operating in high humidity. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.

Chromating will retard or prevent the formation of white corrosion products on surfaces exposed to various environmental conditions as well as delay the appearance of asstm from the basis metal.

The thickness of electrodeposited cadmium coatings shall be determined by the applicable test methods. Link to Active This link aztm always route to the current Active version of the standard.

Cadmium coatings are used for corrosion resistance and for corrosion prevention of the basis metal part. The as-deposited coating Type I is useful for the lowest cost protection in a mild or noncorrosive zstm where b766 formation of white corrosion products is not detrimental or harmful to the function of a component.
