It can also be electrodeposited on aluminum, brass, beryllium copper, copper, nickel, and powder metallurgy parts. Land Use and Development.

The thickness of electrodeposited cadmium coatings shall be determined by the applicable test methods. Cadmium coatings are used for corrosion resistance and for corrosion prevention of the basis metal part. Note 1-Cadmium is deposited as a coating principally on iron and steel products. Corrosion products formed on cadmium are tightly adherent.

Cadmium is deposited as a coating principally on iron and steel products.

ASTM-B, –

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 coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution. ASTM B Cadmium Plating Cadmium plating is applied in the automotive, aerospace, and military fields, beneficial for its reliability, consistent coverage, and cost efficiency.

This specification covers the requirements for electrodeposited cadmium coatings on products of iron, steel, and other metals. This allows for proper functioning during corrosive exposure of moving parts, threaded assemblies, valves, and delicate mechanisms without jamming with debris.

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. Electrodeposited cadmium coatings shall be classified on the basis of thickness as Class 25, 12, 8, and 5. SinceKeystone has been a leader in the metal finishing industry. 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.

Nonmagnetic Coatings on Magnetic Basis Metals. 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. Our finish choices include:. The lubricity of cadmium plating is used on springs for doors and latches and for weaving machinery operating in high humidity. 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.

Are you sure you want to empty the cart? The prime purpose of the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance. 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.

At Keystone Corporation, our baking process prevents the occurrence of hydrogen embrittlement, helping ensure a more durable product, and our electrodeposited method improves the bonding of paint and adhesion, allowing you the option of an attractive final finish or allowing for the application of sealants or chromates axtm the cadmium finish. We are proud to offer high quality electrodeposited cadmium plating for electronic, aerospace, mining, and defense industries.

The coating shall be essentially pure cadmium produced by electrodeposition usually from an alkaline cyanide solution. The plating shall be applied after all basis metal heat treatments and mechanical operations. Unlike zinc, cadmium does not build up voluminous corrosion products on the surface. Historical Version s – view previous versions of standard. The prime purpose of the supplementary chromate finishes Types II and III on the electroplated cadmium is to increase corrosion resistance.

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

Cadmium shall be deposited directly on the basis metal part without an undercoat of another metal except when the part asfm either stainless steel or aluminum and its alloys. 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 part without an undercoat of another metal except when the part is either stainless steel or aluminum and its alloys.

The basis metal shall be subjected to such cleaning procedures as necessary to ensure a surface satisfactory for subsequent electroplating. Corrosion products formed on cadmium are tightly adherent.

Chromating will retard or prevent the formation of white corrosion products on surfaces exposed to various environmental conditions as well as 7b66 the appearance of corrosion from the basis metal.
