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

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

When electroplated nickel is required to have higher hardnesses, astm b689 wear resistance, certain residual stress values and certain leveling characteristics, sulfur and other astm b689 are incorporated in the nickel deposit through the use of certain addition agents in the electroplating solution.

Cobalt salts are bb689 added to the plating solution to produce harder nickel alloy deposits.

Active view current version of standard. Type 1, coatings electroplated from solutions not containing hardeners, brighteners, or stress bb689 additives; Type 2, electrodeposits used at astm b689 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 astm b689 dispersed submicron particles such as silicon carbide, tungsten carbide, and aluminum oxide that are present to increase hardness and wear resistance at specified temperatures.

For the effect of such additives, see Asym 4 and Annex A3. Metal parts shall undergo pre- and post-coating treatments to reduce the risk of hydrogen embrittlement, astm b689 peening.
