Влияние ВЧ-магнетронного кальций-фосфатного покрытия на выход никеля из подложек NiTi в водные растворы

Влияние ВЧ-магнетронного кальций-фосфатного покрытия на выход никеля из подложек NiTi в водные растворы

Abstract

Представлены результаты исследования морфологии поверхности, фазового и элементного состава кальций-фосфатных покрытий на поверхности NiTi, сформированных методом высокочастотного магнетронного распыления, после их растворения в физиологическом растворе или дистиллированной воде. Покрытия, напыленные при мощности 30 Вт, рентгеноаморфны и полностью растворяются в течение 42 дней выдержки в растворе и не оказывают влияния на скорость выхода никеля. Поликристаллические покрытия, полученные при мощности 290 Вт, малорастворимы. Скорость выхода токсичного никеля из поверхностных слоев NiTi в окружающую среду снижается в 7...10 раз.

The surface morphology, phase and elemental composition of calcium phosphate coatings deposited on NiTi substrates by rf-magnetron sputtering prior and after exposure to either 0,9 % NaCl physiological solution or distilled water were investigated. The coatings 208 Summaries deposited at 30 W were amorphous and completely dissolved after 42 days of exposure to the media they did not influence on the release of nickel. Polycrystalline coatings deposited at 290 W weakly dissolved and decreased in 7...10 times the release of toxic nickel ions from the surface layers of NiTi to surrounding media.
