Rather than depending upon historical precedent within individual companies, ASTM standards can codify the results, rendering them universally accepted. I need info like tank liners, cathode material, voltage and amp requirements, bath temp, etc. Hello, David and Eddie. James Watts — Navarre, Florida 2 of 2 simultaneous responses A. If you are curious about Nadcap, the meeting results should be available on their website at the end of the month.

We are researching either chromate surface conversion CAA or PAA for better bonding performance, but are getting conflicting information from various anodizing sources.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. If the document is revised or amended, you will be notified by email.

See D [link by ed. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to f3933.


Causes of such differences may be? Ray Handwerker – Atm, Pennsylvania. Cynthia Gosselin guest blogger, ChemQuest. With aluminum playing a larger role in vehicle production, surface preparation of that naturally aging substrate is critical to achieving bonding success. This discussion is limited to single-lap specimens and shear strength only for simplification. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. However, many of the basic tests and ideas for quality control, etc.

We have no amendments or corrections for this standard. Reviewing this guide brings perspective not only to the product under development, but also any necessary testing. The method may be revised or supplemented, as necessary, to include methods based on proven performance. I run a small job shop and I’m just seeking to help a customer out while he does some samples for adhesive bonding tests.

Standard Guides for Automotive and Aerospace Adhesives from ASTM

Is it possible for an aluminum surface to have too low of a surface roughness for phosphoric acid anodizing? A multi-rack has two or three anode racks between each set of cathodes.

It uses sulfuric acid anodizing at many sites, and has a phosphoric acid anodizing operation in one building. Originally published as D— As the voice of the U.


As the voice of the U. Can anyone tell me what equipment is needed to phosphoric anodize aluminum? Material selection should be made by those having expertise in the adhesives field after careful consideration of the design and the performance required of the part, the environment d9333 which it will be exposed, the attachment process to be employed, the inherent properties of the material not covered in this document, and the economic factors. Subscription pricing is determined by: I am working at a US Air Force base.

Phosphoric acid anodizing per BAC5555 and ASTM D3933-98

You may delete a document s3933 your Alert Profile at any time. I need info like tank liners, cathode material, voltage and amp requirements, bath temp, etc. One option was to eliminate the entire process and propose Ion Beam Assisted Deposition treatment dd3933 the components. If Boeing’s BAC spec is still active, then it would be prudent to consider it’s use. For alloys with a lot of Chrome, the aztm will become a greenish color.
