摘要
采用化学镀制得钴硼磁性合金镀层。利用X射线衍射技术、透射电子显微技术和扫描电子显微技术研究了镀层在镀态以及不同热处理温度下的组织结构。另外 ,研究了热处理温度对镀层硬度和矫顽力的影响。钴硼合金在镀态下为非晶态结构 ,经热处理后 ,镀层向晶态转变 ,在 40 0℃时 ,硬度和矫顽力达最大。
Magnetic cobalt-boron alloy deposits were prepared by electroless plating. Microstructure of the alloy deposit at varied temperatures was studied by means of X-ray diffraction, transmission electron microscopy and scanning electron microscopy. In addition, the effect of thermal treated temperature on hardness and coercive force of cobalt-boron alloy deposit was studied. Results show that cobalt-boron alloy deposit is amorphous at room temperature, which transfers to crystalline after thermal treated, hardness and coercive force of the alloy deposit are maximum after thermal treated at 400℃.
