Laboratory Investigation of the Active Nitridation of Graphite by Atomic Nitrogen

reactive-flow model. The reaction efficiency for graphite nitridation was derived from the interpolated N-atom concentration and the measured graphite mass loss for a given test time. The reaction efficiency, defined as the fractionof N-atom collisions with the surfacethatresult in the title reaction, wasfoundto increase from � 0:2 � 10 � 3
