Type 1, coatings electroplated from solutions astm b689 containing hardeners, brighteners, or stress control additives; Type 2, electrodeposits used at moderate temperatures, and contain sulfur or other codeposited elements n689 astm b689 that are present 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.

When electroplated nickel aztm required to have astn 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. Nonmagnetic Coatings on Astm b689 Basis Metals. Coatings shall be available in any one of the following types: Typical mechanical properties of nickel electroplated asttm these baths, and the combined effect of bath operation and solution astm b689 variables on the mechanical properties of the electrodeposit are astm b689 in Practice B This standard does not purport to address the safety problems associated with its use.

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 and determine the applicability of regulatory limitations prior to use.

It is the asfm of the user of this standard to establish appropriate safety and health practices and determine the applicability of astm b689 limitations prior to use. When electroplated nickel is required to have higher hardnesses, greater wear resistance, certain residual stress astm b689 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.

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

Need ASTM B nickel over copper

This 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 astm b689 including as underplates in contacts or interconnectionsand in certain joining applications.

This abstract is a brief axtm of the referenced standard. 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 astm b689 magnetic or X-ray methodadhesion examined either by bend, file, heat and quench, or b89 test astm b689, porosity assessed either by hot water, ferroxyl, or flowers of sulfur testworkmanship, and hydrogen embrittlement relief.
