Tunable multifunctional corrosion-resistant metallic coatings containing rare earth elements

Fabrication of Sputtered Ce/La, La/Ce Oxide Bilayers on AA6061 and AA7075 Aluminum Alloys for the Development of Corrosion Protective Coatings

“…The corrosion pathway of these lanthanides has also been widely discussed and it is associated with the cathodic areas blocked by precipitation of a film of lanthanide oxide/hydroxide [ 7 , 8 , 9 , 10 ], but it strongly depends on the metallic substrate. Additionally, a variety of approaches enables the deposition of metallic coatings containing rare earth (RE) elements for corrosion protection [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ].…”

Performance of a Magnesium-Rich Primer on Pretreated AA2024-T351 in Full Immersion: a Galvanic Throwing Power Investigation Using a Scanning Vibrating Electrode Technique

“…[4][5][6] Previous work on rare element-based corrosion-resistant metallic coatings has established how multi-function coatings with various modes of corrosion protection, such as sacrificial anode protection and inhibitor release can simultaneously provide barrier protection as well as active corrosion protection. [33][34][35] One critical issue in active protection is the capacity of the reservoir of chemical inhibitor and its release characteristics. [33][34][35] Another critical issue in active corrosion protection systems is determining the distance over which a coating can provide corrosion protection.…”

[7][8][9][10][11][12] The distance over which an active corrosion protection system can protect a scratch or a defect exposing a bare metal surface is termed 'throwing power'.…”
