Hydriding of Titanium.
Abstract
The overall goal of this project is to evaluate the performance of grade II titanium in sea water applications. The reason for undertaking this work is that the US Navy would like to use titanium in a number of critical applications, where it would come in contact with sea water at elevated temperatures. Although the general reputation of titanium is that it is quite corrosion resistant in these environments, there is the possibility that it could pick up sufficient hydrogen from this environment to become hydrided and thus lose its mechanical integrity. The work done in the first year of this program has addressed the following issues. A literature survey has been conducted on the behavior of grade II titanium in sea water applications. The corrosion potential of grade II titanium has been measured as a function of temperature, pH, and salt concentration. Mechanical tests have been performed which determine the change in ductility of grade II titanium as a function of electrochemical potential, pH, strain rate, and sample geometry. The effect of galvanic coupling on the corrosion potential of grade II titanium and its ability to form hydrides has been investigated.The results verify the good response of grade II titanium for this application.
