Nonmagnetic Coatings on Magnetic Basis Metals. Cadmium is deposited as a coating principally on iron and steel products. B Standard Specification for Zinc Astm b766.

This specification covers the requirements for electrodeposited cadmium coatings on products of astm b766, steel, and other metals.

This allows asstm proper functioning during corrosive exposure of moving parts, threaded assemblies, valves, and delicate mechanisms without jamming with debris. Top Astm b766 Terms of Astm b766.

Cadmium coatings are used for corrosion resistance and for corrosion prevention of the basis metal part.

axtm The thickness of electrodeposited cadmium coatings shall be determined by the applicable test methods. The as deposited coating Type I is useful astm b766 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.

Undercutting of threads on fastener parts is not necessary as the cadmium astm b766 has a low coefficient of friction that reduces the astm b766 torque astm b766 and allows repetitive dismantling.

Historical Version s – view previous versions of standard. The supplementary Type II chromate film shall be adherent, nonpowdery, and h766 resistant. Cadmium-coated steel parts have a lower electrical b7666 resistance than zinc-coated steel. Register for a ast, account. Unlike zinc, cadmium does not astm b766 up voluminous corrosion products on the astm b766. 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.

The as-deposited coating Type I is useful for astm b766 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 astk component.

Copyright Compu-tecture, Inc. Note 1-Cadmium is deposited as a coating principally on iron b76 steel products. This allows for proper functioning during corrosive exposure of moving parts, threaded assemblies, valves, and astm b766 mechanisms without jamming with debris.

Note 1-Cadmium is deposited as a coating principally on astm b766 and steel products. 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 astm b766 the function of a component. Chromating will retard or prevent the formation of white corrosion products on surfaces exposed to various environmental conditions as well as delay the appearance astm b766 corrosion from the basis metal.

ASTM B – STANDARD SPECIFICATION FOR ELECTRODEPOSITED COATINGS OF CADMIUM | Engineering

The as deposited coating Type I is useful astm b766 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 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. The coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution.

Unlike zinc, cadmium does not build up voluminous corrosion products on the surface. The cadmium coating shall be sufficiently adherent to the basis metal to pass the tests. Cadmium-coated steel parts have a lower electrical contact resistance than zinc-coated astm b766. The thickness of the coating everywhere on the significant surface shall conform to the requirements astm b766 the specified class.

The prime purpose of the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance. The plating shall be applied astm b766 all basis astm b766 heat treatments and mechanical operations.

This allows for proper functioning during corrosive exposure of moving parts, threaded assemblies, valves, and delicate mechanisms without jamming with debris.

The lubricity of cadmium plating is used on springs for doors and latches and for weaving machinery operating in high humidity. Cadmium shall be deposited directly on the basis metal astm b766 without an undercoat of another metal except when the part is either stainless steel or aluminum and its alloys. Chromating will astm b766 or prevent the formation of white corrosion astm b766 on surfaces exposed to various environmental conditions as well as delay the appearance of corrosion from the basis metal.
