Oxidation behaviour of particle reinforced MoSi2 composites at temperatures up to 1700 °C, Part I: Literature Review

Abstract

In the first part of this paper the results of a literature review are presented. An overview of the oxidation behaviour in air and in combustion environments of both pure MoSi2 and MoSi2 composites in the temperature range from 400 to 1650 °C is given. The second part of this paper reports about our results from oxidation tests with selected MoSi2 composites (containing 15 vol.-% Al2O3, Y2O3, ZrO2, HfO2, SiC, TiB2, ZrB2, or HfB2, respectively) from different development stages at temperatures in the pest region as well as up to 1700 °C. The third part describes the oxidation behaviour of the optimised MoSi2 composites developed on the basis of the results from part II.
