利用复合电镀技术,通过向电镀溶液中加入平均粒度为75 nm的Al粉的方法在Ni基材上制备了Ni-28.0mass%Al纳米复合涂层,XRD和TEM分析表明,Al纳米颗粒均匀分布在Ni纳米晶粒中.1050℃氧化实验表明:Ni-28.0 mass%Al纳米复合镀层的氧化速度明显低于单Ni镀层及Ni基材的,这是因为在氧化过程中Ni-Al纳米复合镀层热生长连续的Al2O3氧化膜. |

A Ni-28.0 mass%Al nanocomposite coating was developed by co-electrodeposition of Ni and Al nanoparticles. XRD characterization and TEM observation indicated that the Al nanoparticles were homogeneously dispersed among the nanocrystalline Ni grains. Oxidation tests at 1050X3 showed that the as-deposited Ni-Al nanocomposite coating exhibited a superior oxidation resistance compared to the electrodeposited Ni coating and the uncoated Ni matrix, due to that the nanocomposite coating has an ability to form a continuous alumina scale. |
