The import temperature of gas turbines is rising, and the issue of corrosion can no longer be ignored, creating an urgent need to develop coatings with high-temperature resistance, corrosion resistance, and good toughness. This study utilized plasma spraying technology to prepare composite AT13 ceramic coatings with 0 wt.%, 5 wt.%, 10 wt.%, and 15 wt.% GO\/Cu (GO:Cu = 1:10) content. It systematically investigated the effects of GO\/Cu doping on the porosity, Vickers hardness, fracture toughness, thermal shock resistance, and corrosion resistance of the AT13 coatings while exploring the corrosion behavior of the composite coatings. The experimental results indicate that doping with GO\/Cu can effectively fill the pores of the coatings, leading to an overall improvement in coating performance. The coating with 10 wt.% doping (G2) exhibited the best comprehensive performance, with a 72% reduction in porosity compared to the original coating, a 23.2% increase in Vickers hardness, a 31.4% enhancement in fracture toughness, and an 83% decrease in corrosion rate. It also demonstrated the best thermal shock resistance, maintaining a relatively intact surface after 31 days of immersion in artificial seawater, with only a few pitting and cracking defects observed in the areas of corrosion.<\/jats:p>","DOI":"10.3390\/ma18102168","type":"journal-article","created":{"date-parts":[[2025,5,8]],"date-time":"2025-05-08T06:47:15Z","timestamp":1746686835000},"page":"2168","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Research on the Corrosion Resistance and Mechanical Properties of Graphene Oxide\u2013Modified AT13 Coatings"],"prefix":"10.3390","volume":"18","author":[{"given":"Yuchen","family":"Xu","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, College of Engineering, Shanghai Ocean University, Shanghai 201306, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6016-8348","authenticated-orcid":false,"given":"Zhenhua","family":"Chu","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, College of Engineering, Shanghai Ocean University, Shanghai 201306, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1484-9692","authenticated-orcid":false,"given":"Jingxiang","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, College of Engineering, Shanghai Ocean University, Shanghai 201306, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wan","family":"Tang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, College of Engineering, Shanghai Ocean University, Shanghai 201306, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Gao","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, College of Engineering, Shanghai Ocean University, Shanghai 201306, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"296","DOI":"10.1111\/j.1559-3584.1985.tb01364.x","article-title":"Application of Variable Speed Constant Frequency Generators to Propulsion-Derived Ship Service","volume":"97","author":"Robey","year":"1985","journal-title":"Nav.
