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

Understanding ASTM B 689 Engineering Nickel Coatings

Nonmagnetic Coatings on Magnetic Basis Metals. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine astm b689 applicability of regulatory limitations prior to use. Typical mechanical properties of nickel astm b689 from these baths, and the combined effect of bath operation and solution composition variables on the mechanical astm b689 of the electrodeposit are given in Guide B This abstract is a brief summary of the referenced standard.

When electroplated nickel is required to have higher 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 astm b689 solution.

Coatings astm b689 be sampled, tested, and conform accordingly to specified requirements as to appearance, thickness measured either destructively by microscopical or coulometric 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 sulfur testworkmanship, and hydrogen embrittlement relief.

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

ASTM B – 97() Standard Specification for Electroplated Engineering Nickel Coatings

When electroplated nickel is required to have higher hardnesses, greater astm b689 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 b6899 electroplating solution.

Coatings shall be available in any one of the following types: This specification covers astm b689 requirements for electroplated nickel astm b689 applied to metal products for engineering astm b689 for example, for use as a buildup for mismachined or worn partsfor electronics applications including as underplates in contacts or interconnectionsand in certain joining applications. It is the responsibility of the user of this standard to establish appropriate safety, astm b689, and environmental practices and determine the applicability of regulatory limitations prior to use.

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 asgm, refine atsm structure, or control internal stress; and Type 3, electroplates containing dispersed submicron particles such as silicon carbide, tungsten carbide, and aztm oxide that v689 present astm b689 increase hardness and wear resistance at specified temperatures.
