摘要

The report covers all important aspects of work carried out during the last six years of this contract. Results from the first five years work are appropriately summarized and referenced. Work carried out during the last year is emphasized. During the last year coated samples were again characterized for thickness uniformity (mechanical stylus), surface topography (SEM) and composition (EDAX analyses) as a function of time. The dependence of strain-to-failure on coating thickness was determined. The effect of aging on bond strength (film adhesion) was investigated using polycarbonate/carbon film composites, as well as titanium and titanium alloy composites. Samples to biological testing were characterized and submitted to the University of Michigan. Finally, a small quantity of implant rings were processed and shipped to collaborating contractors.
