... compound in the form of deagglomerated abrasive suspensions. If there is too much of the polishing compound, or it is applied too frequently, the abrasive particles can roll on the cloth surface and not actually cut the sample. This creates features such as edge and fiber rounding and erosion of the sample...

..., the one major shortcoming of C-C composites is their oxidation susceptibility. At temperatures above 950 °F (510 °C), both the matrix and the fiber are vulnerable to oxidation if they are not protected from oxygen exposure. The two primary oxidation protection methods are external coatings and internal...
