Cadmium coatings are used for corrosion resistance and for corrosion prevention of asfm basis metal part. It can also be electrodeposited on aluminum, brass, beryllium copper, copper, nickel, and powder metallurgy parts.

ASTM B766 – 86(2015)

The prime purpose of the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance. 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 corrosion from the basis metal.

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 corrosion from the basis metal.

The basis metal shall be subjected to such cleaning procedures as necessary to ensure a surface satisfactory for subsequent electroplating.

The coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution. Undercutting of aztm 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.

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

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

The supplementary Type II chromate film shall be adherent, nonpowdery, and abrasion resistant. Nonmagnetic Coatings on Magnetic Basis Metals. Nonmagnetic Coatings on Magnetic Basis Metals.

Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated steel. Note 1-Cadmium is deposited as a coating principally on iron and steel products. Historical Version s – view previous versions of standard. Search book title Enter keywords for book title search. Land Use and Development.

Unlike zinc, cadmium does not build up voluminous corrosion products on the surface. Are you sure you want to empty the cart? The thickness of electrodeposited cadmium coatings shall be determined by the applicable test methods.

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. The cadmium coating shall be sufficiently adherent to the basis metal to pass the tests.

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.

Active view current version of standard. 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. B Standard Specification for Refined Lead. The lubricity of cadmium plating is used on springs for doors and latches and for weaving machinery operating in high humidity.

F Asttm Specification for Driven Fasteners: 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. The plating shall be applied after all basis metal heat treatments and mechanical operations. Corrosion products formed on cadmium are tightly adherent. Unlike zinc, cadmium does not build up voluminous corrosion products on the surface.

This abstract axtm a brief summary of the referenced standard. Nonmagnetic Coatings on Magnetic Basis Metals. This specification covers the requirements for electrodeposited cadmium coatings on products of iron, steel, and other metals. Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated steel.
