CONTAINED IN VOL. 02.05, 2017 Defines the requirements for electroplated nickel coatings applied to metal products for engineering applications, for example, for use as a buildup for mismachined or worn parts, for electronic applications, including as underplates in contacts or interconnections, and in certain joining applications.

1.1This 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 parts, for electronic applications, including as underplates in contacts or interconnections, and in certain joining applications.

1.2Electroplating of nickel for engineering applications (Note 1) requires technical considerations significantly different from decorative applications because the following functional properties are important:

1.2.1Hardness, strength, and ductility,

1.2.2Wear resistance,

1.2.3Load bearing characteristics,

1.2.4Corrosion resistance,

1.2.5Heat scaling resistance,

1.2.6Fretting resistance, and

1.2.7Fatigue resistance.

Note 1—Functional electroplated nickel coatings usually contain about 99 % nickel, and are most frequently electrodeposited from a Watts nickel bath or a nickel sulfamate bath. Typical mechanical 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 Guide B832. 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. For the effect of such additives, see Section 4 and Annex A3. Cobalt salts are sometimes added to the plating solution to produce harder nickel alloy deposits.

1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
