Abstract:

The corrosion behavior of an aluminum-graphite composite in a salt water solution has been investigated to qualitatively characterize the effect of galvanic coupling prevalent between the aluminum matrix and the graphite fibers. A comparison is made with aluminum-boron and with other materials joined to graphite blocks. Although the corrosion rate of the aluminum matrix is increased by the presence of the graphite fiber, the aluminum-graphite composite is only slightly more reactive than the aluminum-boron composite in the salt water solution.
