21、rganization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been estab
22、lished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardizat
23、ion.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with
24、 the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

28、TC 107, Metallic and other inorganic coatings, Subcommittee SC 3, Electrodeposited coatings and related finishes, in accordance with the agreement on technical cooperation between ISO and CEN (Vienna Agreement).This fourth edition cancels and replaces the third edition (ISO 2082:2008), which has bee

Cadmium is anodic and corrodes sacrificially, thus protecting ferrous basis metals even when exposed through pores or pits
30、 in the cadmium. Electrodeposited cadmium coatings have traditionally been applied to iron or steel from alkaline cyanide solutions, but in recent years, environmental concerns and regulations have led to increased use of acid sulfate, neutral chloride and acid fluoborate cadmium solutions.Because t
31、he appearance and serviceability of electroplated cadmium coatings are influenced by the surface condition of the basis metal, agreement should be reached between the interested parties that the surface of the basis metal is satisfactory for electroplating.Although concerns have been raised about th
32、e use of cadmium due to safety and environmental effects, there are critical applications, often aerospace-related, where the unique properties of electrodeposited cadmium coatings, for example, their corrosion resistance, intrinsic lubricity, ductility, electrical conductivity and low contact resis
33、tance, make continued use of cadmium coatings necessary.The corrosion resistance of electroplated cadmium coatings and their tendency to tarnish when handled can be improved by applying chromate conversion and other supplementary coatings.Chemical conversion coatings that do not contain hexavalent c
34、hromium are commercially available and their use is becoming more and more popular. The appearance of these substitutes may be different from those produced with hexavalent chromium. Due to the REACH Regulations, however, the use of hexavalent chromium compounds will be banned in Europe from Septemb
35、er 2017 except where specifically authorized. Other conversion coatings that are chromium-free are also available. Substitutes are required to satisfy the corrosion requirements given in this document. ISO 2017 All rights reserved vBS EN ISO 2082:2017This page deliberately left blankMetallic and oth
36、er inorganic coatings - Electroplated coatings of cadmium with supplementary treatments on iron or steel (ISO 2082:2017)DANGER Cadmium vapour is highly toxic by inhalation. During heat treatment, all precautions should be taken to ensure that no person is exposed to it. Attention is also drawn to th
37、e danger arising from welding, soldering or heating and other operations, in which the possibility that cadmium will be vaporised exists. Because of its toxicity, cadmium should not be employed as a coating for any article that will come in contact with food or beverages or containers in contact wit
38、h these items or any household goods.1 ScopeThis document specifies the requirements of electroplated coatings of cadmium with supplementary treatments on iron and steel. It includes information that is to be supplied by the purchaser to the electroplater, and describes coating requirements, includi
39、ng those for heat treatment before and after electroplating.It is not applicable to coatings applied to sheet, strip or wire in the non-fabricated form, to close-coiled springs, or for purposes other than protective, intrinsic lubricity, ductility, electrical conductivity and low contact resistance
40、use.This document does not specify requirements for the surface condition of the basis metal prior to electrodeposition with cadmium.The coating thickness that can be applied to threaded components can be limited by dimensional requirements, including class or fit.Additional information on corrosion
