Corrosion behavior of L-PBF Ti6Al4V with heat treatments in the F--containing environments
Source abstract
Abstract
In this study, the corrosion resistance of L-PBF Ti6Al4V with heat treatments in F - -containing environments is investigated. Under the condition of 0.20 M NaF, the corrosion resistance decreases with heating temperature and holding time increasing, while an opposite phenomenon is presented as the concentration increase to 0.50 M. The corrosion product layer in the solution with 0.20 M NaF is constituted of AlF 3 particles and replaced by 4AlOF·TiOF 2·H 2O in the other condition. The corrosion resistance of L-PBF Ti6Al4V depends on the corrosion product layer, and the difference in the layer formation process is responsible for the contrary phenomenon.
