Conventional methods for evaluating chipping resistance typically rely on visual inspection according to special standards, which is subjective and prone to inconsistency. This study aims to develop an automated machine vision and image processing method for the objective detection and grading this effect. Coated panels were prepared and tested in accordance with the PSA D241312-H (Peugeot) standard to report varying degrees of chipping. High-resolution images were acquired under uniform lighting. An image processing pipeline combining contrast enhancement, thresholding, and contour-based analysis was implemented to identify and classify damaged areas based on the chip size and chip distribution. The results demonstrated that the proposed system could accurately detect even subtle or complex defects that were often challenging for human observers, while providing consistent and reproducible grading. In contrast, visual evaluations by four experienced inspectors showed substantial variability, as reflected by large standard deviations across samples. Despite this disagreement, the system achieved a strong correlation with the inspectors’ mean ratings (R = 0.86), highlighting both its accuracy and its ability to provide a more stable reference. Moreover, the automated approach reduced inspection time by approximately a factor of seven compared to manual evaluation.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"23 5","pages":"2791 - 2803"},"PeriodicalIF":3.4,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional protective coatings mainly rely on passive barrier effects, such as blocking the penetration of electrolytes and oxygen, but once micro-defects and cracks occur, their long-term protective effect will be limited. To overcome these drawbacks, active anticorrosion strategies using corrosion inhibitors have gained increasing attention. However, traditional corrosion inhibitor carriers (such as LDH, nanocapsules, graphene oxide, MXenes, and molybdenum disulfide) have problems, such as premature release of inhibitors, poor interfacial compatibility, or limited long-term stability. Covalent organic frameworks (COFs) are novel crystalline porous polymers featuring ordered channels, tunable functional groups, and excellent chemical stability, making them promising for intelligent nano-containers as corrosion inhibitors. This review provides a comprehensive overview of the latest developments in anti-corrosion coatings utilizing COFs, mainly on different framework types - imine-linked, triazine-linked, and β-ketoenamine-linked frameworks. Among them, the β-ketoenamine covalent organic framework represented by TpPa-1 exhibits excellent structural stability and inhibitor loading capacity. We discuss the design strategies, release mechanisms, and the synergistic effect of COFs in combining passive barrier protection with active inhibitor release. Finally, we summarize the current challenges and future development prospects to stimulate the research and development of next-generation COF-based anti-corrosion coatings, making them more responsive and durable.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"23 4","pages":"1869 - 1896"},"PeriodicalIF":3.4,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148519449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From an industrial standpoint, corrosion represents a substantial economic burden, contributing no direct value to production while imposing additional maintenance, operational, and replacement costs. Conventional corrosion prevention and protection methods are often expensive and frequently associated with environmental hazards, necessitating the exploration of more sustainable alternatives. The ideal corrosion mitigation approach should be cost-effective, operationally simple, technically feasible, and, most importantly, environmentally benign. In this context, green corrosion inhibitors have emerged as a promising class of materials, generally offering an effective, low-cost, and eco-friendly solution with minimal environmental footprint. Their rising industrial relevance has spurred extensive research activity focused on their development, optimization, and application. Green corrosion inhibitors encompass a broad spectrum of substances, both traditional and recently developed. Conventional green inhibitors include plant extracts, essential oils, biomolecules, expired pharmaceuticals, rare-earth metal complexes, ionic liquids, and amino acids along with their derivatives. In contrast, modern innovations in this domain have led to the development of advanced green inhibitors such as volatile corrosion inhibitors, nanocomposite-based systems, metal–organic frameworks (MOFs), deep eutectic solvents (DESs) and MXene. These novel materials generally exhibit enhanced corrosion inhibition efficiency and align with principles of green chemistry and sustainable engineering. This chapter provides a comprehensive overview of various categories of green corrosion inhibitors, highlighting key examples and their mechanisms of action. Emphasis is placed on both well-established and emerging systems, underscoring their potential to revolutionize corrosion mitigation in an environmentally sustainable manner.</p></div>","PeriodicalId":619,"journal":{"name":"Journal of Coatings Technology and Research","volume":"23 4","pages":"1751 - 1792"},"PeriodicalIF":3.4,"publicationDate":"2026-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148519501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent progress in MXene synthesis, including HF-based, molten-salt, electrochemical, and fluoride-free methods, has expanded material accessibility and improved structural stability. When incorporated into polymer coatings, MXenes create compact, tortuous pathways that impede the ingress of corrosive species, while polymers contribute flexibility, adhesion, and film-forming capability.

Electrochemical impedance spectroscopy (EIS), polarization testing, and salt-spray evaluations consistently show that these materials are better at preventing corrosion than traditional graphene- and CNT-based nanocomposites.
