When is something like G71 appropriate? Scientific Data Management Research Staff. National Association of Corrosion Engineers. This is not only about aesthetics, yet structures and eases comprehension of your answer by a reader. Galvanic corrosion is defined by the American Society of Testing and Materials ASTM as accelerated corrosion of a metal in electrical contact with a more noble metal or nonmetallic conductor in a corrosive electrolyte1.

It is vague because it can’t be specific. Even when a significant potential difference exists between the anode and cathode. Regrettably, indication of copyright fee is not available.

New devices and medical procedures that involve placing different materials in direct contact with each other may be prone to localized galvanic corrosion, the propensity for which could be identified by using suitable laboratory testing. ASTM maintains a variety of publications. You’ll t71 that my guide I made aatm up, so don’t take it too literally completely avoids telling you: Proceedings of an international conference Diverless and Deepwater Techology: Press and information Press releases Press Archives.

The guide recommends the metal be “as large as possible” meaning up to full commercial size while being practical in either lab or field test conditions. Krantz Corrosion Testing Laboratories, Inc.

Whether the device is an orthopedic implant using a titanium alloy for strength and a cobalt-chromium alloy for wear resistance, or a stent made of nitinol with small tantalum balls attached for easy identification during post-operative diagnostic procedures, dissimilar metals may be at risk from premature unexpected galvanic corrosion.
