Cobalt salts are sometimes added to the plating solution to produce harder nickel alloy deposits. For the effect of such additives, see Section 4 and Annex A3.

Coatings shall be available in any one of the following types: It is the responsibility aetm the user of this standard to establish appropriate safety and health asmt and determine the applicability of astm b689 limitations prior to use.

Metal parts shall undergo pre- and post-coating treatments to reduce the risk of hydrogen embrittlement, and peening. Nonmagnetic Coatings on Magnetic Astm b689 Metals. When electroplated nickel is required to have higher hardnesses, greater wear resistance, certain residual astm b689 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.

Typical astm b689 properties of nickel electroplated from these baths, and the combined effect of bath operation and solution composition variables on the mechanical properties of the electrodeposit are given in Astm b689 B Nonmagnetic Coatings on Magnetic Basis Metals.

Typical mechanical properties of nickel electroplated from these baths, and the combined astm b689 of bath operation and solution composition variables on the mechanical properties of the electrodeposit are given in Practice B 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 testporosity assessed either by hot water, ferroxyl, or flowers of sulfur testworkmanship, and hydrogen embrittlement relief.

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 astm b689 certain addition agents in the electroplating solution.

Cobalt salts are sometimes added to the plating solution to produce harder nickel alloy deposits. Type 1, coatings electroplated from solutions not containing hardeners, brighteners, or stress control additives; Type astm b689, 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 stress; and Type 3, electroplates containing dispersed submicron particles such as silicon carbide, astm b689 carbide, and aluminum oxide that are present to increase hardness and wear resistance at specified astm b689.
