摘要

WC and TiB ₂ were added into Ti(C,N)-304ss cermet to relieve an abnormal oxidation behavior of Fe in this cermet. During high-temperature oxidation (650 °C), the volume swelling of WO ₃ eliminated the gap led by the volume shrinkage of TiO ₂ . Liquid B ₂ O ₃ covered the oxidation surface or filled in cracks, forming a dense oxidation layer. As a result, the abnormal oxidation behavior was relieved. The oxidation mechanism was investigated using FESEM, XRD, LSCM, and AFM. Fe atoms outward diffused to the surface along with the TiO ₂ /304ss boundary forming ring-structure oxide and across the TiO ₂ generating aggregated oxide on TiO ₂ surface.
