Corrosion resistance of Nd-Fe-B magnets with PVD protecting coatings modified by pulsed plasma treatment
The combination of PVD and pulsed plasma treatment has been applied to Nd-Fe-B based magnets to provide enhanced corrosion resistance. The corrosion behavior of plasma treated Nd-Fe-B sintered magnets with Fe₈₀B₂₀ film in naturally aerated sodium sulphate solutions have been studied. The corrosion b...

Комбінацію PVD технології та імпульсної плазмової обробки застосовано для підвищення корозійної стійкості магнітів Nd-Fe-B. Вивчалася корозійна поведінка магнітів Nd-Fe-B, покритих феробором Fe₈₀B₂₀ після плазмової обробки, в умовах природної аерації у водних розчинах сульфату натрію низької концентрації. Оцінку корозійної поведінки досліджували електрохімічними методами. Встановлено, що на корозійну стійкість зразків значно впливає попередня обробка вихідної поверхні, виконана до плазмової обробки або до нанесення плівки феробору Fe₈₀B₂₀. Комбинация PVD технологии и импульсной плазменной обработки использована для повышения коррозионной стойкости магнитов Nd-Fe-B. Изучено коррозионное поведение магнитов Nd-Fe-B, покрытых пленкой Fe₈₀B₂₀ после плазменной обработки, в условиях природной аэрации в водных растворах сульфата натрия низкой концентрации. Оценку коррозионного поведения материалов проводили электрохимическими методами. 'Установлено, что на коррозионную стойкость образцов значительно влияет предварительная обработка исходной поверхности, выполненная до проведения обработки плазмой или до нанесения пленки ферробора Fe₈₀B₂₀. 2008 Article Corrosion resistance of Nd-Fe-B magnets with PVD protecting coatings modified by pulsed plasma treatment // O.M.
