摘要：

An investigation has demonstrated the effects of the high temperature tests on corrosion resistance and the integrity of protective silicon carbide cladding by applying the tests on a microfuel elements in contact with components made of steels, such as 08kh18N10T and EI-847 (05kh15N16M3B). Microfuel elements from two batches with different uranium oxide kernel diameters and multilayer cladding consisting of pyrolytic carbon and silicon carbide were chosen for the investigations. Two types of assemblies, one consisting of a crucible made of high temperature ceramic based on Al 2O3 or mullite corrundum, which contained two steel disks separated by a weighed amount of microfuel elements. At the end of the tests, the microfuel elements, disks, and tubes was determined, and the integrity of protective coatings was evaluated. It can be concluded that at 1110-1180°C, the corrosion depth in the steel in the air over 4 h was 0.15 mm.
