Preserved Fulltext
The aim of this study is to determine the cyclic oxidation behavior of cubic boron nitride (c-BN) and hexagonal boron nitride (h-BN) in air atmosphere at elevated temperatures. For this purpose, as-received powders of both compounds were first characterized by XRD and SEM. c-BN and h-BN powders were shaped by cold pressing for oxidation studies. Tests were performed in air atmosphere at 800 • C and 1000 • C for 5, 10, 15 and 20 hours. After each oxidation test, the mass changes were measured.
