Abstract

This specification establishes the requirements for electrodeposited tin-nickel alloy coatings from aqueous solutions intended for the corrosion protection of fabricated articles of iron, steel, zinc-base alloys, copper, and copper alloys. This specification does not apply to sheets, strips, or wires in the fabricated form. It also may not be applicable to finely threaded articles, but the decision to use the coating on such components may be made by the purchaser. Coating grades shall be designated by a service condition number, which indicates the severity of exposure for which the coating is intended, and a coating thickness notation. Iron and steel specimens shall undergo pre- and post-coating treatments for reducing the risk of hydrogen embrittlement. Coatings shall be sampled, tested, and conform to specified requirements as to appearance (visible defects), composition, thickness (assessed either by microscopical, magnetic, coulometric, beta backscatter, or X-ray spectrometry), adhesion (determined either by burnishing, or heat-quench test), and integrity (including gross defects, mechanical damage, and porosity).
