A novel method is described for measuring the depth of erosion damage on ceramics that exhibit a stress‐induced martensitic transformation. The technique is applied to metastable, tetragonal zirconia, eroded with silicon carbide particles. The damage depth data are compared with fracture depth predictions from single‐particle studies, on the premise that the surface transformation zone can be attributed to the presence of impact fractures. The reasonable correlation obtained adds credence to the suggestion that single‐particle tests are pertinent to erosion prediction in the plastic response regime
