| Abstract: | The surface glass films of MoSi 2 and MoSi 2 matrix multiphase materials aged at high temperature for a long time were studied.The forming process of surface glass films was also traced by electric measurement method.The forming rate and mechanism of surface glass film were investigated.The oxidation mechanism of MoSi 2 and MoSi 2-SiC were studied and the oxidation rate order is as follows:MoSi 2 >MoSi 2-SiC.For the matrix,the forming order of glass film is as follows:MS>MSM>MSA. |
