Cobalt salts are sometimes added to the plating solution to produce harder nickel alloy deposits. Coatings shall be available in any one of the following types: This specification covers the requirements for electroplated nickel coatings applied to metal products for engineering applications for example, astm b689 use as a asfm for mismachined or astm b689 partsastm b689 electronics applications including as underplates in contacts or interconnectionsand in certain joining applications.

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

This standard does atsm purport to address the safety astm b689 associated with its use. This abstract is a brief summary of the b89 standard. 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 b6689 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, and aluminum oxide that are present to increase hardness and wear resistance at specified temperatures.
