Protective vacuum-arc coatings on zirconium alloy fuel cladding to prevent catastrophic accidents at nuclear reactors
The processes of vacuum arc deposition of multicomponent coatings based on Cr, Ti, Al, Fe, Y, Si, and their nitrides with a thickness of 5…9 μm for the protection of zirconium alloy fuel rods were developed. The composition, structure, and mechanical properties of the coatings were determined by ele...

Розроблено процеси вакуумно-дугового осадження багатокомпонентних покриттів на основі Cr, Ti, Al, Fe, Y, Si та їх нітридів товщиною 5…9 мкм для захисту оболонок твелів з цирконієвих сплавів. Склад, структуру та механічні властивості покриттів визначено методами електронної мікроскопії, енергодисперсійної рентгенівської спектроскопії, рентгеноструктурного аналізу та наноіндентування. Проведено порівняльні дослідження захисних властивостей покриттів при високотемпературному окисленні труб Zr1Nb. Було виявлено, що металеві покриття з високим вмістом хрому мають високі захисні властивості під час випробувань в імітованих умовах аварії. Вони одночасно стійкі до високотемпературної корозії на повітрі при температурі 750…1100 °С і у водяній парі при термоциклуванні до 1020 °С. Тверді нітридні покриття, які значно зміцнюють поверхню цирконієвого сплаву і добре захищають від окислення на повітрі, менш ефективні в парах води при термоциклуванні. Розроблені у ННЦ ХФТІ покриття та процеси синтезу можуть бути корисні при вдосконалені топливних оболонок із сплавів цирконію провідного світового виробника ядерного палива Westinghouse Electric Company. 2023 Article Protective vacuum-arc coatings on zirconium alloy fuel cladding to prevent catastrophic accidents at nuclear reactors / A.S.
