Superhydrophobic surfaces possess excellent passive anti-icing properties owing to their outstanding water repellent ability. However, in literature, most methods for preparing anti-icing surfaces are complicated and environmentally unfriendly, making them unsuitable for surface protection of polar ships. In this paper, a simple laser etching method was used to prepare superhydrophobic anti-icing surface on DH36 steel, especially for polar ships. Contact angle of the prepared superhydrophobic surface was about 161°, and sliding angle was only 3° Meanwhile, icing time was 13.4 times longer than that of untreated steel surface. In addtion, such superhydrophobicity remains after 10 icing and de-icing cycles. Adequate surface roughness and adsorption of low surface energy substances in vacuum drying furnaces provide excellent hydrophobicity on this surface. No organic coating was used in this research, which could be applied to the anti-icing in polar environments with strict environmental protection requirements, providing a new idea for clean and green anti-icing technology for polar ships.</div></div>","PeriodicalId":100337,"journal":{"name":"Corrosion Communications","volume":"19 ","pages":"Pages 28-37"},"PeriodicalIF":0.0,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the relatively blurred edges and unclear textures of SEM images, a crack image super-resolution network based on global mixed attention (GMA-net) is proposed for application to SEM images of organic coatings. The recognition results of the images processed with GMA-net were compared with those of the original images and the images processed with bicubic method, respectively. The results show that this method not only refrains from destroying the clarity of the original images but also greatly outperforms bicubic method in terms of precision, recall, mAP50 and mPA50–95, which are improved by approximately 23.1 %, 32.4 %, 36.4 % and 26.7 %, respectively.
