pH值对镀铁层性能及结构的影响

Effect of pH on the Properties and Texture of Electrodeposited Iron

研究了在不同pH值条件下所获得的无刻蚀镀铁层的硬度、金相组织及耐蚀性。结果表明,在pH值为0.7时,镀铁层致密、结合牢固、具有最佳的结构及性能,镀铁层的(113)织构最强,且随pH值的升高而增强。

The textures of electrodeposited iron obtained from chloride solution at different pH conditions were studied in detail. The microhardness, morphology and corrosion resistance were also examined and measured. The results showed that a compact and adherent iron deposit with good mechanical properties could be achieved at pH 0.7, and the (113) strong texture increassed with decreasing pH values.
