Abstract The plasma electrolytic oxidation (PEO) coatings were prepared on low carbon steel from silicate electrolyte without and with Al nanoparticles, respectively. The structure, composition, anti-wear and anti-corrosion properties of the PEO coatings were investigated. The results indicated that the Al nanoparticles in the silicate electrolyte turned into alumina during the PEO process and reduced the amount of iron oxides in the coating. The PEO coating prepared from silicate electrolyte with Al nanoparticles showed enhanced wear resistance due to the formation of alumina. Furthermore, the coating was characterized by sealed pores on the surface, different from the open pores on the surface of PEO coating prepared from silicate electrolyte without Al nanoparticles. The modified structure and the changed composition of PEO coating by introducing Al nanoparticles in the electrolyte significantly improved the corrosion resistance of the coating, demonstrated by the electrochemical corrosion and salt spray tests.

铝纳米粒子硅酸盐电解液制备低碳钢等离子电解氧化涂层的表征

摘要 分别以不含和含铝纳米粒子的硅酸盐电解质为原料,在低碳钢上制备等离子电解氧化 (PEO) 涂层。研究了PEO涂层的结构、成分、抗磨和抗腐蚀性能。结果表明,硅酸盐电解质中的铝纳米颗粒在 PEO 过程中转变为氧化铝,减少了涂层中氧化铁的含量。由于氧化铝的形成,由硅酸盐电解质与铝纳米颗粒制备的 PEO 涂层显示出增强的耐磨性。此外,该涂层的特点是表面孔隙封闭,不同于由不含铝纳米颗粒的硅酸盐电解质制备的 PEO 涂层表面的开孔。
