Oxidation behavior of Al2O3 reinforced MoSi2 composite coatings fabricated by vacuum plasma spraying
Source abstract
Abstract
Abstract MoSi 2 , MoSi 2 –10 vol.% Al 2 O 3 , MoSi 2 –30 vol.% Al 2 O 3 (denoted as MA0, MA1, MA3, respectively) coatings were fabricated by vacuum plasma spraying (VPS), and their oxidation behavior was examined at low temperature (500 °C) and high temperature (1500 °C). The test at 500 °C showed that the addition of Al 2 O 3 effectively restrained the pest oxidation of MoSi 2 . The MA1 coating had satisfactory fluid surface and presented good oxidation resistance at 1500 °C. However, the MA3 coating showed worse oxidation resistant behavior compared with the MA0 coating because of mullite formation.
