Abstract
Due to the limited surface structure of optical device, the mold materials are extremely difficult to be processed at micro-nano scale, especially considering high temperature oxidation. Ir-Ni-Ta-(B) metallic glasses become the optimal candidate for the molding materials of optical devices. In this work, the high temperature oxidation behaviors for Ir-Ni-Ta-(B) during the isothermal and continuous heating process were studied. It is found that the addition of boron can enhance the oxidation resistance of Ir-Ni-Ta. What is more, Ir-Ni-Ta-(B) has formed a unique four-layer structure. This study reveals the oxidation mechanism and provides new insights into the development of new materials.
