ZIF-8-based micro-arc oxidation composite coatings enhanced the corrosion resistance and superhydrophobicity of a Mg alloy

Facile In Situ Growth of Zif-8 Nanosheets with Enhanced Anti-Corrosion Performance for Carbon Steel in Seawater

“…The potentiodynamic polarization curves of the blank and Zif-8 coating samples are shown in Figure 3a. It is well known that a more positive E corr and a lower j corr translate to a better anti-corrosion performance [3,4]. As expected, the Zif-8 coating sample exhibits an E corr value of −302 mV (Figure 3b), which is more positive than that of the blank sample.…”

“…As one of the most valuable industrial products, carbon steel-based materials have been used broadly in marine environments, such as in bridges, pipelines and ships [1][2][3]. However, the corrosion behavior of carbon steel in seawater not only threatens public safety, but also induces huge economic losses and environmental pollution [4]. Thus, the development of an effective corrosion-protection strategy to decrease the corrosion rate of carbon steel has become an urgent challenge.…”

“…Currently, the introduction of a passivation layer on the surface of carbon steel is one of the most promising approaches used to improve the corrosion resistance of carbon steel [1,4], which can effectively avoid its direct contact with a corrosive medium. For example, metal oxide films [5], layered double hydroxides [6], and organic silica coatings [7] have been designed as the passivation layers for carbon steel reinforcements [8].…”

Metal–organic frameworks on versatile substrates

“…93 Apart from single metal substrates, metal alloys are one of the cheapest and most commonly used substrates and have been widely explored over the past few decades. [96][97][98][99][100][101][102][103][104][105][106] For example, Kazemian et al used stainless steel as a substrate to fabricate Cu-BTC (H 3 BTC trimesic acid) crystals, as shown in Fig. 1d.…”

In Vitro Degradation and Photoactivated Antibacterial Activity of a Hemin-CaP Microsphere-Loaded Coating on Pure Magnesium

“…Among various preparation methods of coatings such as micro-arc oxidation (MAO) [ 8 , 9 ], electrophoretic deposition [ 10 , 11 ], layer-by-layer assembly [ 12 , 13 ], chemical vapor deposition [ 14 ] and chemical conversion [ 15 , 16 ], MAO has been extensively used for surface modification of Mg-based alloys because of its remarkable wear resistance as well as high hardness [ 17 ]. However, the MAO coating with porous structures is vulnerable to penetration by a corrosive medium.…”
