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 astk. Land Use and Development. The coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution. The coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution.

No items in cart. 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. Corrosion products formed on cadmium are tightly adherent. The prime purpose of the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance. The lubricity of satm plating is used on satm for doors and latches and for weaving machinery operating in high humidity.

It can also be electrodeposited on aluminum, brass, beryllium copper, copper, nickel, and powder metallurgy parts. This specification covers the requirements for electrodeposited cadmium coatings on products of iron, steel, and other metals. If you like to setup a quick demo, let us know at support madcad. 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.

Cadmium is deposited as a coating principally on iron and steel products. Please login to your authorized staff account to use this feature.

The plating shall be applied after all basis metal heat treatments and mechanical operations. This specification covers the requirements for electrodeposited cadmium coatings on products of asmt, steel, and other metals.

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. The thickness of the coating everywhere on the significant surface shall conform to the requirements of the specified class. Note 1Cadmium is deposited as a coating principally on iron and steel products.

ASTM B766 Cadmium Plating

Remember me for one month. The lubricity of cadmium plating is asgm on springs for doors and latches and for weaving machinery operating in high humidity.

Our finish choices include:. Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated steel. Print 1 2 3 4 5 page sstarting from page current page. The cadmium coating shall be sufficiently adherent to the basis metal to pass the tests. This allows for proper functioning during corrosive exposure of moving parts, threaded assemblies, valves, and delicate mechanisms without jamming with debris.

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

The supplementary Type II chromate film shall be adherent, nonpowdery, and abrasion resistant. Historical Version s – view previous versions of standard.
