Ion Beam Modification of Advanced Titanium Alloys


EMSL Project ID
18001

Abstract

The Navy is constantly seeking new materials or new processing methods to improve the life of components used in underwater structural applications such as submarines and ships. Advanced titanium alloys are very good candidates for seaborne structural applications where a combination of strength and corrosion resistance is required. A novel technique utilizing Pacific Northwest National Laboratory (PNNL) facilities may be employed to modify the surface of these alloys to improve their corrosion and strength, and thus improve the life of the submersible components, while maintaining their beneficial properties from the bulk of the material. The technique is called ion beam implantation and has been shown to increase corrosion resistance and wear resistance of structural alloys including titanium alloys. However, there are multiple methods of utilizing this technique to alter surface properties to beneficially impact properties. It is our goal to optimize these processes in their impact on corrosion resistance and wear in titanium alloys used for naval submersible structural applications.
