| 中文摘要: |
| 在p型<100>单晶硅表面制备了Ni68Co24P8 化学镀层,分析了镀层的显微结构、耐蚀性及磁学性质。结果表明:Ni68Co24P8 镀层为非晶结构,表面均匀分布着直径约为0.5~4.2μm的球状团簇;在10.0%NaOH溶液和3.5%NaCl溶液中,镀层表现出活化—钝化—过钝化的腐蚀行为,而在1.0%H2SO4 溶液中,镀层表面无法形成钝化膜,耐蚀性大幅下降;室温下,Ni68Co24P8 镀层呈典型的软磁特征,饱和磁化强度为33.4A·m2/kg。 |
| 英文摘要: |
| Electroless Ni68Co24P8 coatings were synthesized on p-type Si<100>substrates. Microstructures corrosion resistane and magnetic property of Ni68Co24P8 coatings were investigated. The results indicate that an amorphous phase for Ni68Co24P8 coatings with 0.5~4.2 μm nodule clusters distributes uniformly on the coating surface. In 10.0%NaOH and 3.5% NaCl solutions Ni68Co24P8 coatings show an active-passive-transpassive behavior. However, in 1.0%H2SO4 solution, no passivation films can be formed and the corrosion resistance of the coatings is decreased prominently. Furthermore, the Ni68Co24P8 coatings exhibite typical soft-magnetic characterization and the saturation magnetization is 33.4 A·m2/kg. |
