Název v původním jazyce

Estimating the quality of thin aluminum layers through their anodizing behavior

Popis výsledku v původním jazyce

Porous anodic alumina (PAA) grown on aluminum bulk, sheets, and foils in aqueous acid electrolytes has received numerous studies due to its unique self-organized nature and diverse potential applications. However, the formation of well-self-ordered PAA on thin aluminum layers on substrates remains a challenge due to the thickness-related limitation for pore selfordering behavior. It is anticipated that the morphology and inner structure of a thin Al layer are important factors influencing further preparation of a high-quality PAA film with a desired morphology and pore configuration. Here we demonstrate that the anodizing behavior during formation of barrier-type alumina films on thin Al layers prepared by various PVD techniques can be effectively used for estimating the suitability of the films as precursor layers for more advanced anodic treatments. In this course, a systematic study was performed on anodizing thin Al layers prepared via (1) thermal evaporation, (2) magnetron sputtering, and (3) ion
