A Review on LDH-Smart Functionalization of Anodic Films of Mg Alloys

“…However, the structural defects formed inevitably during the PEO process would facilitate the inward motion of the corrosive medium into the substrate. In this regard, the sealing of such structural defects by the inclusion of nano-particles to the electrolyte during PEO or by using the post-treatments by boiling water, organic compounds, and sol-gel films have been proposed by several research groups [ 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 ]. Similar to the anodized samples, the successful formation of the LDHs on the PEO-coated samples not only caused an effective sealing of the structural defects but also released the corrosion inhibitors, providing the function of self-healing properties [ 19 , 43 , 78 , 79 , 80 , 81 , 82 , 83 ].…”

Optimization of Surface Properties of Plasma Electrolytic Oxidation Coating by Organic Additives: A Review

“…It should be pointed out that the modification of plasma discharges via the utilization of electrolyte composition has been in the spotlight since the combination of available elements generates many different compounds and potentially leads to different plasma behavior. Two major types of electrolytes are those containing organic compounds and those containing inorganic compounds [21][22][23][24][25][26]. While numerous investigations showed that organic compounds tend to be precluded in the coating layer during coating growth, the use of inorganic compounds generally showed successful incorporation [21].…”
