The pervasive issue of metal corrosion in various industrial environments, especially marine settings, incurs significant economic costs and hazardous failures. Traditional protection methods, although diverse, fall short durability environmental adaptability, necessitating advanced solutions, such as two-dimensional (2D) materials, including graphene, layered double hydroxides, boron nitride, MXenes, MoS2. These materials offer exceptional barrier properties against corrosive agents due to their high surface area minimal thickness, enhancing the lifespan reliability assets under harsh conditions. Innovations self-repairing coatings application techniques, automated spraying rapid photocuring, further augment effectiveness. In this Review, recent advancements development 2D material-enhanced are reviewed, underscoring potential revolutionizing through improved performance metrics sustainability. challenges prospects these novel also discussed, highlighting need for research overcome hurdles realize full uses.

Research on bone regeneration has always been an intense and challenging field of tissue engineering. Biodegradable metals represent a novel class biomaterials combining superior mechanical qualities with capacity to promote growth. Among them, magnesium (Mg) its alloys have proposed as innovative for grafting therapy due their non-toxic nature comparable properties bones. In addition, they are lightweight, biocompatible biodegradable. They offer several advantages over other implant metals, including reduced stress-shielding effects unnecessity second surgery remove them. Unfortunately, clinical application is limited the rapid degradation rates in rather aggressive physiological conditions. Therefore, development Mg-based implants possessing controlled accordance kinetics healing necessary. On hand, protective yet biodegradable surface coatings emerged useful strategy fulfill diverse requirements, effective corrosion resistance. Calcium orthophosphates (abbreviated CaPO4) excellent candidates producing such well tolerated by living organisms. However, high chemical reactivity low melting point, grafts require specific parameters successful CaPO4 deposition. This paper reviews currently available preparation methods deposits Mg alloys, aiming build up comprehensive knowledge framework deposition techniques, processing parameters, performance measures terms resistance, adhesion strength biocompatibility. The literature analysis shows that increase ability magnesium-based metallic withstand improve biocompatibility surfaces all cases.

Abstract Low‐density magnesium (Mg) alloys are excellent engineering materials, and can significantly reduce energy consumption by replacing existing steel aluminum materials. However, Mg species susceptible to corrosion, especially in harsh environments (high‐temperature or acidic), severely limiting the range of practical applications. Here, 2D covalent organic framework (COF) is synthesized with pore diameters ranging from 1.5 2.9 nm obtain ultrafast nanofluidic channels. Loaded silver (Ag + ) ions, 2‐mercaptobenzimidazole (2‐MB) inhibitors immobilized COF channels through bridges. Based on strong metal‐complexing capability, Ag ions precipitated various corrosive media (Cl − , Br I SO 3 2− S 2 O 4 CO PO 3− ); meanwhile, 2‐MB rapidly released channels, forming a passivation film as corrosion barrier protect substrate. After integration commercial polyethersulfone (PES), COF‐based coating exhibits high repairing capability achieving 100% damage restoration within 7 h, outperforming all coatings alloys. Notably, shows almost complete protection after being treated respective 473 K, acidic (pH ≈4.0), alkaline ≈10.0) environments.
