Ni-Al2O3纳米复合镀层的氧化性能研究Oxidation resistance of electrodeposited Ni-Al2O3 nanocomposite coating
周月波,张海军
摘要(Abstract):
采用复合电镀技术,通过向普通电镀溶液中加入平均粒度为90nm的Al2O3粉的方法在Ni基材上制备了Ni-Al2O3纳米复合涂层,SEM/EDAX分析表明,Al2O3纳米颗粒不仅均匀分布在Ni纳米晶中,而且还细化了基体Ni的晶粒尺寸。1000℃氧化实验表明:弥散分布在镀层中的Al2O3纳米粒子并没有明显提高Ni的氧化性,但通过阻碍氧化过程中Ni的外扩散从而改变了NiO膜的形成过程。
