Studies of Carbon-Surfaced Polymeric, Metallic, and Ceramic Biomaterials.

Abstract

The primary goal of this program has been to characterize the engineering and biological properties of carbon-surfaced polymeric, metallic, and ceramic composites. A variety of engineering studies were carried out which established the adhesion, strain-to- failure, wear, fatigue, and fluid friction erosion characteristics of test specimens coated with a thin layer of isotropic (LTI-like) carbon. These studies, while not complete, have demonstrated that carbon-coated composites possess the necessary engineering properties for use in prosthetic devices. Coated test specimens were supplied for biological testing by collaborating contractors and others. The biological test results to date, taken as a whole, indicate that composites surfaced with thin isotropic carbon films exhibit biochemical properties similar to those of LTI carbon. As a service to other contractors, about 950 implant rings were processed. The injection mold was completed. Implant rings were molded from five different polymers. jg p.4
