摘要: 用化学镀技术在碳钢表面制备Ni-P及Ni-P-PTFE纳米非晶镀层，探索镀层制备关键技术与工艺；通过扫描电镜（SEM）、X射线能谱仪（EDS）、X射线衍射技术（XRD）进行镀层微观结构、化学组成、相组成的分析与表征；用电化学参数测试及腐蚀增重评价镀层试样防腐性能。结果表明：在碳钢表面成功制备了具有非晶特点的Ni-P及Ni-P-PTFE镀层，Ni-P镀层表面致密平整，Ni-P-PTFE 镀层具有表面孔洞的形貌特征；电化学测试及腐蚀增重分析表明，Ni-P镀层防腐性能良好，Ni-P-PTFE镀层则由于复合界面的存在而防腐性能稍逊，但二者均可实现对基材碳钢明显的防腐保护作用。

Abstract：The Ni-P and Ni-P-PTFE coatings were experimentally electroless deposited on the surface of carbon steel in the present study. The key preparing process was explored and the as-prepared coatings of Ni-P and Ni-P-PTFE were then characterized using SEM, EDS and XRD. The electrochemical polarization curves and the weight increases of the coated samples in the seawater were conducted to assess the anti-corrosion behaviors of the two coatings. The results indicated that the Ni-P and Ni-P-PTFE coatings have been successfully electroless deposited on the surface of carbon steel. The surface microstructure observations showed that the Ni-P coating was smooth and compact rather than the Ni-P-PTFE coating. Although the results from polarization curves and weight gains indicated that the Ni-P-PTFE coating had anti-corrosion behavior slightly poorer than the Ni-P coating due to the presence of the composite interface in the Ni-P-PTFE coating, the two coatings prepared in this study could provide carbon steel with valuable protection from seawater attack.

Key words： carbon steel electroless deposition Ni-P Ni-P-PTFE
