ISO 2082:2017规定了对钢铁进行补充处理的镉电镀层的要求。它包括由买方提供给电镀商的信息,并描述了涂层要求,包括电镀前后的热处理要求。
它不适用于所涂的涂料
-以非装配形式进行薄板、带材或线材,
-关闭螺旋弹簧,或
-用于保护性、固有润滑性、延展性、导电性和低接触电阻以外的用途。
ISO 2082:2017未规定镉电沉积前基底金属表面条件的要求。
适用于螺纹部件的涂层厚度可能受到尺寸要求的限制,包括等级或配合。
关于耐腐蚀性、冲洗和干燥、批量加工零件和铬酸盐转化涂层染色的其他信息,见附录C。
ISO 2082:2017 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, including 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 use.
ISO 2082:2017 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 resistance, rinsing and drying, processing parts in bulk and dyeing of chromate conversion coatings is given in Annex C.
