Abstract
This paper presents the results of an experiment on high-temperature oxidation of SiC coating of a prototype HTGR fuel in an oxygen environment under the following experimental conditions: the maximum temperature of the samples with linear heating is 1400 °C; heating rate – 10 °С/min.
According to the results of the experiments, dependences of the change in the composition of the gas mixture in the corrosion chamber with linear heating of the sample were obtained. A qualitative analysis of corrosion data and microstructural research data was carried out before and after the corrosion experiment.
The results obtained allow us to estimate the corrosion resistance and the loss of the operational properties of SiC coatings on prototype HTGR fuel.
