摘　　要：利用化学镀方法在NdFeB磁性材料表面制备了非晶态Ni-Cu-P合金镀层,并运用X射线衍射(XRD)研究了不同温度热处理后(200、300、350、380、400、500℃)非晶态镀层结构的变化。结果表明:随着加热温度从200℃增加到500℃,镀层结构由镀态下的非晶态结构逐渐转变为晶态结构,晶态转变温度为350~380℃;镀层硬度由非晶态的486.9 HV0.1增加为晶态的766.4 HV0.1。Amorphous Ni-Cu-P alloy coatings were obtained by means of electroless plating method on NdFeB permanent magnets materials, and the structural changes of the amorphous coatings heat treated at 200℃, 300℃, 350 ℃ , 380 ℃, 400 ℃ and 500 ℃ were analyzed by using X-ray diffraction （XRD）. The results show that with the increase of temperature from 200 ℃ to 500 ℃, the coatings structures changed from amorphous to crystalline, and the transformation temperature is about 350 ℃ to 380 ℃. Hardness of the Ni-Cu-P alloy coatings increases from 486.9 HV0.1 of amorphous state to 766.4 HV0.1 of crystalline state.
