Oxidation of aluminum in the presence of nanodiamond additives

Resumo

The study of the kinetics of aluminum oxidation process in the presence of modified nanodiamonds and diamond-containing soot (DND-TAN and DCS-boron, respectively) shows their impact on the growth and quality of anodic films: the film thickness and the current efficiency have increased by 13 % at 2 A/dm² and using DCS-boron; the number of pores has been reduced two-fold using nanodiamond additives; no pinholing has been detected; micro-hardness of the oxide coating has increased 1.5 to 1.6 times (up to 1020 kg/mm²).
