Cadmium is deposited as a coating principally on iron and steel products. Corrosion products formed 7b66 cadmium are tightly adherent. Search book title Enter keywords for book title search.

ASTM-B, –

Are you sure you want to empty qstm cart? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Unlike zinc, cadmium does not build up voluminous corrosion products on the surface.

Electrodeposited cadmium coatings shall be classified on the basis of thickness as Class 25, 12, 8, and 5. This specification covers the requirements for electrodeposited cadmium coatings on products of iron, steel, and other metals. B Standard Specification for Refined Lead. The prime purpose of the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance.

The cadmium coating shall be sufficiently adherent to the basis metal to pass the tests. Corrosion products formed on cadmium are tightly adherent. Cadmium coatings are used for corrosion resistance and for corrosion prevention of the basis metal part. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

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.

Print 1 2 3 4 5 page sstarting from page current page. Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated steel.

Cadmium asmt 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 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 basis metal shall be subjected to such cleaning procedures as necessary to ensure a surface satisfactory for subsequent electroplating. The thickness of the coating everywhere on the significant surface shall conform to the requirements of the specified class.

ASTM B766 – 86(2015)

The lubricity of cadmium plating is used on springs for doors and latches and for weaving machinery operating in high humidity. The basis metal shall be subjected to such cleaning procedures as necessary to ensure a surface satisfactory for subsequent electroplating. Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated steel.
