1.1 This practice is intended to serve as a guide for producing adherent electrodeposits of nickel on nickel alloys. Only those methods that are well known and generally practiced are included. Methods that have been used successfully but not on a broad scale are not included. Once nickel is applied, other metals may be electroplated on the product.

1.2 This 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.

This practice serves as a guide for the preparation of nickel alloy substrates that shall undergo electroplating processes involving adherent nickel electrodeposits. Surface cleaning may be done either by degreasing (including vapor degreasing, solvent wash, emulsion cleaning, or soak cleaning), or electrolytic alkaline cleaning. The choice of cleaning procedure to use shall be decided upon by the condition of the surface. Conversely, surface activation treatment shall be performed either by anodic-cathodic sulfuric acid treatment, acid-nickel chloride treatment, or anodic etching in a low pH watts bath. The choice of activation treatment to employ shall be determined by the condition of the surface and the specific type of nickel alloy involved.
