    摘要:

    基于不同Ni、P原子比设计合成了Cu-Ni-P系列合金,并针对其特有的微观组织及物相提取过程进行了研究。研究发现,Cu-xNi-4.5P合金铸锭内含有Cu和多种Ni-P物相,如Ni5P4、Ni12P5及Ni3P。经过熔体旋淬处理后,其薄带试样中磷化物主要以Ni12P5和Ni3P形式存在。此外,对比发现,合金内镍含量的增加在一定程度上促使了磷化物相的粗化。通过调控合金的凝固行为及物相提取工艺,可获得多级孔结构的Ni-P颗粒,其孔洞是由于腐蚀过程中铜基体、共晶组织内及固溶部分的铜被去除而形成的。通过对典型合金进行物相提取,实现了可控合成磷化物,这对于拓展功能性磷化物的应用具有促进作用。

    Abstract:

    Cu-Ni-P alloys with different atomic ratios of Ni:P (2:1, 3:1, 4:1 and 5:1) were designed, and the microstructure characteristics and phase extraction treatments of ingots and melt-spun ribbons were discussed. Results show that Cu-xNi-4.5P ingots are composed of Cu and multiple Ni-P phases, including Ni5P4, Ni12P5 and Ni3P. With melt-spun process, the phosphides mainly exist in the form of Ni12P5 and Ni3P compounds. Meanwhile, further increasing nickel concentration of alloys can cause the structure-coarsening of phosphides in some degree. By controlling the solidification behavior and phase extraction process, Ni-P particles with multistage pore structure can be obtained, in which the pores are formed due to the etching of Cu dendrites and Cu existing in eutectic structure and solid solution region. Thus, phase extraction from metallic alloys provides a new controllable method to synthesize functional multistage porous phosphides.
