Rinsing should be sufficiently long and vigorous to assure removal of soluble residue chemicals, or particles. Surface preparation for magnesium alloys which is closely associated with corrosion ast shall involve vapor, alkaline-detergent solution, chromic acid, and sodium hydroxide acid degreasing; anodic treatment; and the use of conversion coatings and wash primers.

A break in the water? The application of these paste systems allows for their use in fairly controlled areas.

Sand blast, grit blast, or vapor hone may be used.

ASTM D2651 – 01(2016)

The major problem is to apply sufficient thickness of coating to prevent corrosion, but not so thick that the bond fails within the coating. It does not address the preparation of cast metals.


Originally published as D — 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 high reactivity of magnesium requires that corrosion-preventative coatings be applied for most service applications. Generally in production, a series of tanks containing the necessary solutions is arranged with overhead cranes to transport parts to be prepared.

A number in parentheses indicates the year of last reapproval. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you ashm attend. Standards should be established and records kept aztm such tests on each lot or vat of solution.

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. Vapor blasting by water or steam and an abrasive is the most effective method and does not warp parts, d6251 done carefully. The surface will exhibit a adtm or lighter color. Oxidation can occur in a very short time, even before the parts are dry.

ICS Number Code Exercise care in using any mechanical method to prevent deep gouges or rough surfaces which are not conducive to good bonding.

Please download Chrome or Firefox or view our browser tips. Parts must be bonded immediately. Material Sulfuric acid 6. Do not allow the time interval between treatment and bonding to exceed 72 h, and cover or wrap all parts during the interval with a non-contaminating vapor barrier material.

This guide covers procedures for preparing various wrought metal surfaces for adhesive bonding. Thorough rinsing follows, usually in warm to hot running water.

On the basis of the results of such an investigation, it may be possible to extend the length of time and establish standards for the interval between surface preparation and adhesive application to? NOTE 1—No entirely foolproof method exists to determine bondability of a metal surface after preparation.

Good bond strengths have resulted by bonding titanium alloys that have been anodized by proprietary processes. Do not allow to dry. A pH reading or acid content of trichloroethane vapor degreasing solution, or both, should be obtained. The values given in parentheses are for information only. Current edition approved Oct.
