Бесхроматная пассивация оцинкованной стали в растворе на основе нитрата лантана
Аннотация
Настоящая работа посвящена разработке технологии осаждения лантансодержащих покрытий в качестве альтернативы традиционным процессам хроматирования, которые в настоящее время не рекомендуются к применению в связи с токсичностью ионов Cr(VI). Разработана процедура получения лантансодержащих покрытий на оцинкованной стали из водных растворов на основе нитрата лантана и пероксида водорода, и изучены их свойства. Установлено, что толщина полученных лантансодержащих покрытий составляет около 135 нм. Обсуждается механизм образования покрытий. Определены оптимальные условия получения покрытий. В результате проведенных исследований показано, что разработанные лантансодержащие пассивирующие покрытия на оцинкованной стали по коррозионной стойкости и защитной способности сопоставимы с хроматными покрытиями и в то же время превосходят их с точки зрения экологической безопасности.
