This specification covers the requirements for electroplated nickel coatings applied to metal products for engineering applications for example, astm b689 use as a buildup for mismachined or worn partsfor electronics applications including as underplates in contacts or interconnectionsand in certain joining applications.

Metal parts shall undergo pre- and post-coating treatments to reduce the risk of astm b689 embrittlement, and peening.

For the effect of such additives, see Section 4 and Annex A3.

This abstract is a brief summary of the referenced standard. When electroplated nickel is required to have astm b689 hardnesses, greater wear resistance, certain residual stress values and certain leveling characteristics, sulfur and other substances are incorporated in the nickel deposit through the use of certain addition agents in the electroplating solution.

Coatings shall be sampled, tested, and conform accordingly to specified requirements as to appearance, thickness measured either destructively by microscopical or coulometric astm b689, or nondestructively by magnetic or X-ray methodadhesion examined either by bend, file, heat and quench, or push testporosity assessed either by astm b689 water, ferroxyl, or flowers of sulfur testworkmanship, and hydrogen embrittlement relief.

Type 1, coatings electroplated from solutions not containing hardeners, brighteners, or stress control additives; Type 2, electrodeposits used at moderate temperatures, and contain sulfur or other codeposited elements or compounds that are present to increase the hardness, refine grain structure, or control internal stress; and Type 3, electroplates containing dispersed submicron particles such as silicon carbide, tungsten carbide, astm b689 aluminum oxide that are present to increase hardness and wear resistance at specified temperatures.
