| 中文摘要: |
| 使用AC-HVAF喷涂工艺分别制备了纳米和微米结构的高铬镍基合金涂层，对两种涂层和20G钢在550℃和650℃表面涂盐情况下的热腐蚀性能进行了研究，并利用配有能谱分析仪的扫描电镜(SEM)和X-ray衍射仪(XRD)对涂层腐蚀产物的形貌、成分和相组成进行了分析。试验结果表明，腐蚀后的两种涂层表面均生成一层连续致密的氧化铬保护膜，可有效抑制腐蚀反应的进程。在相同腐蚀条件下，纳米结构涂层比微米结构涂层具有更低的腐蚀增重，显示出更优异的抗热腐蚀性能。 |
| 英文摘要: |
| Nanostructured and conventional high chromium content nickel based alloy coatings were prepared by AC-HVAF technique. The corrosion kinetics of two coatings and 20G steel were studied at 550℃ and 650℃ . The morphologies and compositions of corrosion products were determined by SEM and XRD. The experimental results indicate that two coatings develop a continuous and compact Cr203 layer, which can further restrain the corrosion process effectively. Under the same corrosion conditions, nanostructured coatings have lower corrosion weight gains and better corrosion resistance than conventional coatings. |
