Recent Trends in the Characterization and Application Progress of Nano-Modified Coatings in Corrosion Mitigation of Metals and Alloys

Nanotechnology is a discipline of science and engineering that emphasizes developing, modifying, characterizing, using nanoscale components in variety applications. Owing to their multiple advantages, including adhesion strength, surface hardness, long-term extra-high-temperature corrosion resistance, improvement interfacial behavior, etc., nanocoatings are efficiently utilized minimize the influence corrosive environment. Additionally, often applied thinner finer concentrations, allowing for greater versatility instrumentation reduced operating maintenance costs. The exemplary physical coverage coated substrate facilitated by fine dimensions nanomaterials significant density grounded boundaries. For instance, fabricated self-healing eco-sustainable inhibitors PAC/CuONPs, PAC/Fe3O4NPs, PAC/NiONPs, with uniform distributions particulate sizes 23, 10, 43 nm, correspondingly, were effective producing PAC/MONPs nanocomposites which exhibited IE% 93.2, 88.1, 96.1, 98.6% carbon steel 1M HCl at optimum concentration 250 ppm. Therefore, this review, further steps taken into exploration corrosion-mitigation potential applications nanomaterial-based nano-modified coatings, nanocoatings, natural source-based metal/metallic ion-based allotrope-based generate defensive film protection against several metals alloys. These have been illuminated through in-depth discussion on characterization techniques such as scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), atomic force (AFM), energy dispersive (EDS), etc. After providing general summary various types protective mechanisms wide media, we subsequently present viewpoint challenges future directions.
