NOTE Other International Standards specify differing electroplating processes.
This document does not specify requirements for properties such as weldability or paintability. The specifications for zinc flake coatings are defined in international standard ISO 10683 and also in European standard EN 13858. Information for design and assembly of coated fasteners is given in Annex A. Zinc flake coatings are non-electrolytically applied coatings, which provide good protection against corrosion.These coatings consist of a mixture of zinc and aluminium flakes, which are bonded together by an inorganic matrix. This document applies to bolts, screws, studs and nuts with ISO metric thread, to fasteners with non-ISO metric thread, and to non-threaded fasteners such as washers, pins, clips and rivets. Specifications for other electroplated coatings and coating systems (tin, tin-zinc, copper-tin, copper-silver, copper, silver, copper-zinc, nickel, nickel-chromium, copper-nickel, copper-nickel-chromium) are included in this document only for dimensional requirements related to fasteners with ISO metric threads. with or without lubricant (integral lubricant and/or subsequently added lubricant). Please contact Whitaker Finishing at 41 or fill out our online form for a quote for your zinc nickel plating requirements. 48 Zinc Nickel and 36 Zinc Barrel Plating Lines. 48 Fully Automated Zinc Nickel Barrel Plating Line. For critical components, it is recommended that. However, baking durations between 2 hours and 24 hours between 200☌ and 230☌ may be suitable depending on the part’s type, size, geometry and mechanical properties, in addition the cleaning and electroplating processes used. Eight hours is considered a typical example of baking duration. In zinc plating according DIN EN ISO 4042, zinc ions are deposited from an. ISO 4042 does not provide exact baking conditions. It mainly applies to zinc and zinc alloy coating systems (zinc, zinc-nickel, zinc-iron) and cadmium, primarily intended for corrosion protection and other functional properties: Alkaline Zinc Nickel Barrel Plated Brackets. The listed coatings are standard coatings according to ISO or DIN with. It also specifies requirements and gives recommendations to minimize the risk of hydrogen embrittlement see 4.4 and Annex B. The requirements related to dimensional properties also apply to fasteners made of copper or copper alloys. This document specifies requirements for electroplated coatings and coating systems on steel fasteners.
