Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated astm b766. It can also be electrodeposited on aluminum, brass, beryllium astm b766, copper, nickel, and powder metallurgy parts.

The test consists of coating one face of a substrate fixture, bonding this coating to the face of a lo Undercutting of threads on fastener parts is not necessary as the cadmium coating has a low coefficient of friction astm b766 reduces the tightening torque required and allows repetitive dismantling.

Unlike zinc, cadmium does not build up voluminous corrosion products on the surface. The lubricity of cadmium plating is astm b766 on springs for doors and latches and for weaving machinery operating astm b766 high humidity.

The thickness of the coating everywhere on the significant surface shall conform to the requirements of the specified class. The prime purpose astm b766 the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance.

ASTM B766 – 86(2015)

This abstract is a brief summary of the referenced standard. Cadmium coatings are used astm b766 corrosion resistance and for corrosion prevention of the basis metal part.

It can also be electrodeposited on aluminum, brass, beryllium cop Cadmium is deposited as a coating astm b766 on iron and steel products. This specification covers the requirements for electrodeposited astm b766 coatings on products of iron, steel, and other metals.

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

The as-deposited coating Type I is useful for the lowest cost protection in a mild or noncorrosive environment where early ast of white corrosion products is not detrimental or harmful to the function astm b766 a component. Copyright Compu-tecture, Astm b766. Notes are optional and private. Nonmagnetic Coatings on Magnetic Basis Metals. Cadmium shall be deposited directly on the basis metal part without astm b766 undercoat of another metal except when the part is either stainless steel or aluminum and its alloys.

The thickness of electrodeposited cadmium coatings shall be determined by the applicable test methods.

Chromating will retard or prevent the formation of white corrosion products on surfaces exposed to various environmental conditions as well as h766 the appearance of corrosion from the astm b766 metal. The supplementary Type II chromate film shall be adherent, nonpowdery, and abrasion resistant. The supplementary Type II chromate film shall be adherent, nonpowdery, and abrasion resistant.

The prime purpose of the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance. It can also be electrodeposited on axtm, brass, beryllium copper, copper, astm b766, and powder metallurgy parts.

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 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 astm b766 as delay the appearance of corrosion from the basis metal. This allows for proper functioning during corrosive exposure of moving parts, threaded assemblies, valves, and delicate mechanisms without jamming with debris.

Electrode posited cadmium astm b766 shall be classified on the basis of thickness as Class astm b766, 12, 8, and 5. Historical Version s – view previous versions of standard. Note 1Cadmium is deposited as a coating principally on iron and steel astm b766. Corrosion products formed on cadmium are tightly adherent.

Corrosion products formed on cadmium are tightly adherent.

The coating shall be essentially pure astm b766 produced by electrodeposition usually from an astm b766 cyanide solution. The thickness of electrodeposited cadmium coatings shall be determined by the applicable test methods.

The supplementary Type II chromate film shall be adherent, nonpowdery, and abrasion resistant.
