Parts are suspended in the vapor zone above the hot liquid and allowed to remain until there is condensation and run off approximately 5 min. Thorough rinsing should follow. Nitric acid-ferric chloride solution degreasing; sulfuric acid-dichromate-ferric sulfate solution etching; and chemical treatment by nitric-acid-sodium chlorite solutions may be used for copper and copper alloy preparation. Surface preparation for magnesium alloys which is closely associated with corrosion prevention shall involve vapor, alkaline-detergent solution, chromic acid, and sodium hydroxide acid degreasing; anodic treatment; and the use of conversion coatings and wash primers.

Surface treatment methods involving both mechanical and chemical techniques are included for aluminum alloys, stainless steel, carbon steel, titanium alloys, magnesium alloys, and copper and copper alloys.

ASTM D2651 – 01(2016)

Somewhat lower bond strength results from this method compared to other methods described. Originally published as D — Box T, Carson, CA Exercise extreme care to ensure removal of all traces of the etchant.


Rinsing should d26551 sufficiently long and vigorous to assure removal of soluble residue chemicals, or particles.

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. The methods may be revised or supplemented, as necessary, to include methods based on proven performance. Some commercial compounds under the classi? Standards should be established and records kept for such tests on each lot or vat of solution.

Previously bonded parts, such as honeycomb core materials, are usually not degreased due to difficulty in removing residue. The surface should be recleaned until the test is passed.

It produces a smut-free surface that can be treated by other chemical processes. The wide variety of individual alloys and heat treatments under each group, the fact that certain adhesives exhibit speci?

Initial treatment is at about 5 to 10 V. Longer dwell times should be avoided. Historical Version s – view previous versions of standard. Generally in production, a series of tanks containing the necessary sstm is arranged with overhead cranes to transport parts to be prepared.

It does not address the preparation of cast metals. Commercially available proprietary solutions may be used. A thorough rinsing with distilled water may be necessary to ensure complete removal. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.


D22651 care to ensure that all abrasive materials grit, sand, cloth, sand paper, or brushes are free from contamination that may be spread or rubbed onto the steel. Dry grit or sand blasting tends to warp thin sheet materials; these methods are suited only for thick-section parts.

Trial bonding followed by testing and evaluation against mechanical strength standards should be conducted to determine initial and continuous effectiveness of a method. The number of times a 2d651 may be repeated depends upon the amount of metal removed in relation to the tolerance requirements for the part and whether clad asym bare metal is used. Do not seal the anodized parts with boiling water before bonding.

The application of these paste systems allows for their use in fairly controlled areas.
