For the effect of such astm b689, see Section 4 and Annex A3. Typical mechanical properties of nickel astm b689 from these baths, and the combined effect of bath operation and solution composition variables on the mechanical properties of the electrodeposit are given in Guide B Coatings shall be available in any ast, of the following types: Coatings shall 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 test atm, porosity assessed either by hot water, ferroxyl, or flowers of sulfur testworkmanship, and astm b689 embrittlement relief.

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

This abstract is a brief summary of the referenced astm b689.

ASTM B Nickel Coating | General Metal Finishing

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 astm b689 the use of certain addition agents in the electroplating solution.

Cobalt salts are sometimes added to the plating solution to produce harder nickel alloy deposits. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices astm b689 determine the applicability of regulatory limitations prior to use.

Astm b689 specification covers the requirements 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 as underplates in contacts or interconnectionsand in certain joining applications.

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

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 electroplating solution.
