Abstract  The oxidation of a silver-based alloy Ag-8Y was studied in 105 Pa and 10-1 5 Pa oxygen at 700℃.The oxidation rate under high P(O2) is very fast and f ollows approximately parabolic rate law,however under low P(O2) is much sl ower and quite irregular with large deviations from parabolic behavior.Under hig h P(O2) the alloy experiences only an internal oxidation of Y without any significant outward Y diffusion,as a result of a fast oxygen penetration.Under l ow P(O2)the alloy forms an almost continuous Y2O3 layer containing Ag particles,plus an internal oxidation zone of Y much thinner than under high P (O2).In both cases pure Ag metal appears on the top surface as a continuous layer for high P(O2) and as separate particles for low P(O2).The int ernal Y2O3 particles in the matrix change shape with depth,being small and g lobular close to the alloy surface but larger and acicular,elongated nearly perp endicularly to the alloy surface,at larger depths.
