摘 要:     研究了离子镀TiN涂层在500~700 ℃间的高温氧化特性,并利用SEM观察和XRD相分析研究了氧化产物的类型及膜失效机制。结果表明,TiN膜的氧化遵循抛物线扩散规律,其氧化产物为金红石型TiO2。与M2和3Cr2W8V相比,TiN膜具有优良的抗氧化性能。以M2为基体的TiN涂层抗氧化性能略高于以3Cr2W8V为基体的TiN涂层。

Abstract:The oxidation properties of TiN coating by ion plating at high temperature were investigated. By means of SEM and XRD, both the type of oxidation product and the failure mechanism of the coating were studied. Results showed that the oxidation of the TiN coating obeys a rule of parabolic diffusion and the oxidation product is rutile TiO2. Compared with matrix M2 or 3Cr2W8V, the TiN coating possesses much more better oxidation property. The oxidation resistance of TiN coating in the matrix of M2 is slightly better than that in the matrix of 3Cr2W8V.
