一种新类型与杆形状捏空材料被无电的免职方法和热处理基于 Nocadia 的形状准备,一种细菌。材料被描绘,它的磁性、电磁、机械的性质被测量。Ni-P 涂层在凹陷到集中的脸的订的安排前从混乱结构转变,这被发现立方(FCC ) 在在 673 K 和身体凹陷以后的 Ni 集中了四角形的 Ni 3 P 发生。在凹陷以后,表面形态学的变化都没被发现。但是细胞质消失, Ni-P 层变得更紧缩。一种新类型有 150 200 nm 的壳厚度的空材料被获得。浸透磁化(女士) ,残余的磁化(M r ) 和 coercivity (H c ) 分别地被提高到 20 emu/g, 2.7 emu/g 和 117.5 Oe。绝缘、磁性的损失分别地被改进到 14 和 0.4。坚硬和有弹性的模量分别地被提起到 1.80 GPa 和 23.79 GPa。都在凹陷前与那些相比显示出大改进。
A new type Ni-P hollow material with rod-shape is prepared by electroless deposition method and heat treatment based on the shape of Nocadia, a kind of bacteria. The material is characterized and its magnetic, electromagnetic and mechanical properties are measured. It is found that the Ni-P coating transforms from a disordered structure before hollowing to an ordered arrangement of face centered cubic (FCC) Ni after hollowing at 673 K and body centered tetragonal Ni3P occurs. After hollowing no change of the surface morphology has been found. But the cytoplasm disappears and the Ni-P layer becomes more compact. A new type hollow material with shell thickness of 150-200 nm is obtained. The saturation magnetization (Ms), remanent magnetization (Mr) and coercivity (Hc) are enhanced to 20 emu/g, 2.7 emu/g and 117.5Oe, respectively. The dielectric and magnetic loss are improved to 14 and 0.4, respectively. The hardness and the elastic modulus are raised to 1.80 GPa and 23.79 GPa, respectively. All show great improvement compared with those before hollowing.
