Abstract

The objective of this study was to measure the stability of certain carbon-graphite materials. To accomplish this, samples of pure graphite and graphite containing boron and titanium carbide impurities were irradiated with a hydrogen plasma flux of energy density {approx} 7 j/cm{sup 2} and {approx} 12 J/cm{sup 2} and hydrogen ion density of {approx} 1 KeV. The samples examined with an electron scanning microscope in order to assess the surface structure and topography. X-ray diffraction data was also obtained for these sample. The experiment indicated that pure graphite suffered the worst corrosion and that graphite containing 10% boron was structurally the most stable and resistant to corrosion.
