Целью настоящей статьи было продемонстрировать повышение коррозионной стойкости двух нержавеющих сталей после нанесения нанослоев. Вопросы, на которые мы хотели ответить, заключались в следующем: как время самоорганизующегося осаждения влияет на компактность нанослоев и на то, как состав стали влияет на осаждение нанопленки, ее компактность и антикоррозийные свойства. Чтобы ответить на эти вопросы, были приготовлены методом погружения самоорганизующиеся молекулярные слои; нанослои характеризовались величиной смачиваемости водой и образцы двух различных нержавеющих сталей с нанопленками и без них подвергались воздействию агрессивных сред (раствор натрий хлорида). Влияние хлорид–ионов на твердые поверхности визуализировали  методом  атомной  силовой  микроскопии  и  характеризуется параметрами шероховатости. Антикоррозийная эффективность вызвано составом поверхности стали, а также различной самоорганизующейся адсорбцией. Время было объяснено экспериментальными данными.

The aim of our experiments was to demonstrate the increase in the corrosion resistance of two stainless steels after nanolayer deposition. The questions we wanted to answer were: how the self–assembled deposition time influences the compactness of the nanolayers and how the steel composition influences the nanofilms deposition, its compactness and the anticorrosion efficiency. To answer these questions self–assembled molecular layers were prepared by dipping technique; the nanolayers were characterized by water wettability values and the two different stainless steel samples with and without nanofilms were subjected to corrosive media (sodium chloride solution). The effect of the chloride ions on the solid surfaces were visualized by atomic force microscopy and characterized by roughness parameters. The anticorrosion efficiency caused by the steel surface compositions as well as by the different self–assembled adsorption time was explained by the experimental data.
