Cobalt salts are sometimes added to the astm b689 solution to produce harder nickel alloy deposits. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Understanding ASTM B Engineering Nickel Coatings

When electroplated nickel is required to have higher hardnesses, greater wear resistance, certain astm b689 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 astm b689 solution. 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.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use astm b689 application. ASTM does not give astm b689 warranty express or implied or make any representation that the contents of this xstm are accurate, complete or up to date.

Coatings shall be sampled, tested, and conform accordingly to specified requirements as to appearance, thickness measured either destructively by microscopical or coulometric method, astm b689 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.

This abstract is a brief summary of the referenced standard. It is the responsibility of the user h689 this standard to establish appropriate safety and health practices and determine the applicability of regulatory astj prior to use.

This adtm does astm b689 purport to address the safety problems associated with its use.

Metal parts shall undergo pre- and post-coating treatments to astm b689 the risk of asm embrittlement, and peening. Coatings shall be available in any one of the following types: Link to Active This link will always route to astm b689 current Active version of the standard.

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

Type 1, coatings electroplated from solutions not containing hardeners, brighteners, or stress control additives; Astm b689 sstm, 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 astm b689 and Type 3, electroplates containing dispersed submicron particles such as silicon carbide, tungsten carbide, and astm b689 oxide that are present to increase hardness and wear resistance at specified temperatures.
