The International Space Station has many laboratories that have been designed by specific countries. These laboratories include the U.S. Laboratory Destiny, the European Space Agency (ESA) Columbus Laboratory, the Japanese Experiment Module and the Centrifuge Accommodation Module, and two Russian Research Modules. The laboratory experiments for the Japanese laboratory require a pressurized water system at 40F and 120F. A titanium shaft was selected due to its advantageous weight and corrosion resistance. However, the system started leaking prematurely during acceptance testing and the titanium shaft was badly corroded. The subsequent failure analysis determined the combination of the rotating titanium shaft with Teflon seals resulted in the formation of hydrofluoric acid and the corrosion of the shaft. This presentation reviews the failure investigation of the titanium shaft and the recommendations provided to alleviate the problem

Speaking on this topic will be Dr. Daniel P. Dennies. Dr. Dennies is an Associate Technical Fellow for the Boeing Company, and has 29 years experience as a metallurgist and performing failure investigations. He authored the book “How to Organize and Run a Failure Investigation,” released in September 2005. The majority of his career has been in the aerospace industry working on projects such as the Space Shuttle Main Engine, the National Launch System, the National Aerospace Plane, expendable launch systems like Delta and Titan and, most recently, the International Space Station.

This should certainly prove to be a very informative topic, as are all of Dan's talks.
