Abstract
An electrodeposited cobalt alloy coating having a composition of 7.1 /- 0.8 at % tungsten was developed to serve as a diffusion barrier bet ween graphite fibers and nickel. A nickel matrix was electrodeposited around the fibers, and the resulting composite was annealed in vacuum under various time/temperature conditions. The coating was shown to in hibit interdiffusion for up to 24 h at 800 degrees C. This represents an improvement of 200 degrees over the uncoated fibers.
