Abstract A coating was prepared on the carbonyl iron powders by plasma electrolytic deposition to improve its corrosion resistance. SiO2 was uniformly coated with the thickness of ~10 nm. The composite powders exhibited superior corrosion resistance in both the NaCl and HCl solutions. The formation of the coating was the result of the electro-chemical absorption and reaction in the electrical field. The aqueous plasma had an important role in activating the surface and optimizing the microstructure of the coating. The superior corrosion resistance makes it available to be used in special environments and has greatly expanded its application fields.

等离子电解沉积提高羰基铁粉的耐腐蚀性能

摘要 采用等离子电解沉积在羰基铁粉上制备涂层以提高其耐腐蚀性能。SiO2 以~10 nm 的厚度均匀涂覆。复合粉末在 NaCl 和 HCl 溶液中均表现出优异的耐腐蚀性。涂层的形成是电场中电化学吸收和反应的结果。水性等离子体在活化表面和优化涂层的微观结构方面具有重要作用。优异的耐腐蚀性能使其可用于特殊环境，大大扩展了其应用领域。
