Thermally sprayed ceramic coatings with varied weight percentages of carbon nanotube (CNT) reinforcement were examined. AISI 1020 steel was coated with yttria-stabilized zirconia (ZrO₂ + 8% Y₂O₃) using the atmospheric plasma spraying (APS) method. The study examined the CNT dispersion in the coating microstructure and evaluated the porosity, bond strength, and corrosion resistance of the coating. In addition, the coating thicknesses were measured. The coatings were characterized using a variety of techniques, including optical microscopy, scanning electron microscopy, image analysis, bond strength testing, and corrosion analysis. According to the findings, adding CNTs to the coatings improved their mechanical characteristics, particularly their hardness and wear resistance. Notably, the best levels of hardness and wear resistance were seen in coatings with a 5 percent CNT reinforcement. Additionally, the coatings' corrosion resistance was enhanced by the inclusion of CNTs. The results of this work show that the mechanical and corrosion properties of thermally sprayed ceramic coatings can be successfully improved by the inclusion of CNTs. This means that these CNT-reinforced coatings have a lot of potential for a variety of applications, such as wear-resistant, corrosion-resistant, and thermal barrier coatings.

对具有不同重量百分比的碳纳米管（CNT）增强材料的热喷涂陶瓷涂层进行了检查。采用大气等离子喷涂（APS）方法在AISI 1020 钢上涂覆氧化钇稳定氧化锆（ZrO ₂  + 8% Y ₂ O ₃ ）。该研究检查了涂层微观结构中的碳纳米管分散情况，并评估了涂层的孔隙率、结合强度和耐腐蚀性。另外，测量涂层厚度。使用多种技术对涂层进行表征，包括光学显微镜、扫描电子显微镜、图像分析、结合强度测试和腐蚀分析。研究结果表明，在涂层中添加碳纳米管可以改善其机械特性，特别是硬度和耐磨性。值得注意的是，含有 5% CNT 增强材料的涂层具有最佳的硬度和耐磨性。此外，由于含有碳纳米管，涂层的耐腐蚀性得到了增强。这项工作的结果表明，通过包含碳纳米管可以成功地改善热喷涂陶瓷涂层的机械和腐蚀性能。这意味着这些碳纳米管增强涂层在各种应用中具有很大的潜力，例如耐磨、耐腐蚀和热障涂层。
