Chromium(III)-substituted hydroxyapatite/silica sol–gel coating: towards novel green coating for corrosion protection of AA2024

A novel Cr-substituted hydroxyapatite (Cr-HA) nanoparticles were synthesized via continuous hydrothermal technique. Moreover, the synthesized material was embedded into a silica sol–gel matrix and applied on an AA2024 substrate to evaluate the corrosion inhibition efficiency of the coating. TEM and...
