Description

1.1 This guide covers cleaning and conditioning treatments used before metal deposition (Section ), and immersion deposit/strike procedures (Section ) that enhance the adhesion of metals that are subsequently applied to aluminum products by electrodeposition or by autocatalytic chemical reduction.

1.2 The following immersion deposit/strike procedures are covered:

1.2.1 Zinc immersion with optional copper strike (6.3).

1.2.2 Zinc immersion with neutral nickel strike (6.4).

1.2.3 Zinc immersion with acetate-buffered, nickel glycolate strike (6.5).

1.2.4 Zinc immersion with acid or alkaline electroless nickel strike.

1.2.5 Tin immersion with bronze strike (6.6).

1.3 From the processing point of view, these procedures are expected to give deposits on aluminum alloys that are approximately equivalent with respect to adherence. Corrosion performance is affected by many factors, however, including the procedure used to prepare the aluminum alloy for electroplating.

1.4 This guide is intended to aid electroplaters in preparing aluminum and its alloys for electroplating.

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. For specific precautionary statements see Section and Appendix.
