| 摘要: |
| 海洋环境中长期服役的船舶、舰载机关键部件存在严重的腐蚀问题。为提高其耐腐蚀性能，采用磁过滤真空弧（FCVA）技术制备不同Al/Ti含量比的亚微米级Ti （Al） N/Ti （Al） CN/Ti （Al） C多元复合多层膜（以下简称TANC）。通过扫描电子显微镜、X射线衍射仪、电化学工作站和盐雾试验机等表征薄膜的形貌、结构和腐蚀性能。结果表明：在盐雾试验中腐蚀形态主要以点蚀为主，随着膜层中Al/Ti含量比的增大，耐腐蚀性提高；电化学腐蚀试验中，亚微米级膜层的自腐蚀电流密度可达到10-7 A/cm2数量级，且随着膜层Al/Ti含量比的增大，腐蚀电流密度从7.73×10-7减小到3.83×10-7 A/cm2，低频区阻抗值从1.19×105增大到4.70×105 Ω·cm2，较基底提高了2个数量级，耐腐蚀性能不断提高；盐雾腐蚀和电化学腐蚀结果一致，高Al含量的TANC耐腐蚀性能最优。通过FCVA技术能实现亚微米级TANC涂层的强防腐效果，该涂层具有发展成为关键部件耐海洋腐蚀涂层的潜力。 |

| Abstract: |
| To improve the anti-corrosion capacity of long-term service ships and aircraft in extremely harsh marine environments, a filtered cathodic vacuum arc (FCVA) method was used to prepare submicron multilayer-structured coating (TANC) with different Al/Ti contents. SEM, XRD, electrochemical and salt spray tests were selected to analyze the morphology, structure and anti-corrosion properties of the films, respectively. The results show that pitting corrosion mainly occurs on the coating surface in the salt spray test. The anticorrosion capacity of the coating was improved with the increase of Al/Ti content. The corrosion current Icorr of the submicron coating can reach the order of 10-7 A/cm2, the Icorr decreases from 7.7291×10-7 to 3.8347×10-7 A/cm2, and the impedance value in the low frequency region increased from 1.19×105 to 4.70×105 Ω·cm2, which is two orders of magnitude higher than the substrate. The strong anti-corrosion effect of submicron TANC coating with high Al content can be achieved by FCVA, which has the potential to develop corrosion resistant coatings. |
