EPR of the transition metal ions in micro-plasma coatings on aluminum alloy D16
Abstract
The influence of micro plasma oxidation (MPO) process conditions on creation of the Al2O3 coatings on aluminum alloy D16 was studied using EPR technique. Aluminum alloy D16 contains alloyed transition metals such as Cu, Mn, Fe, Ni, Ti, being incorporated into the coatings structure during MPO processes. EPR data on transition metal ions allow estimating an appearance of a high temperature phase of Al2O3 due to difference in incorporation coefficients and in the EPR parameters of transition metal ions in low and high temperature Al2O3 phases of MPO coatings. These data show that no high temperature Al2O3 phases were created during anodic MPO process.
