Ion Beam Implantation of Titanium Alloys to Improve Durability in Structural and Biomedical Applications
EMSL Project ID
24696
Abstract
Titanium alloys with high strength-to-weight ratios have vast potential in the automotive, aerospace, and biomedical fields. The automotive and aerospace industries are seeking more fuel efficient vehicles and titanium alloys are a viable alternative to reduce weight of critical components. In valves, suspensions, gears, and springs, high fatigue strength, wear resistance, and corrosion resistance are essential properties. Titanium alloys, such as Ti-6Al-4V, are used in biomedical applications and enhancing wear and corrosion resistance of the alloy will improve the value of the material in this field. Property enhancement can be accomplished using ion beam implantation to alter the surface structure while retaining the desirable bulk properties of the material. The effects of the surface treatments on structure, fatigue, and wear resistance will be quantified and optimized. Earlier studies using ion beam implantation have investigated its potential to improve these properties; however, novel characterization and testing tools that were not available for previous studies will be employed to develop a thorough understanding of the processing-structure-property relationships resulting from ion implantation in this industrially important alloy system.
