The result shows that with the addition of rare earth elements, ultrasonic irradiation and magnetic field, the chemical component, surface configuration, microstructure and properties of electroless co - ni - b and co - fe - b alloy changes remarkably. such kind of change can be described as the followings. firstly the depositing speed of electroless alloy bath is raised while the polarizability and cathodic overpotential are reduced ; secondly the surface quality of the alloy coating and adhesion of the coating and matrix are improved ; thirdly in the coatings the content of the elements in the transient group increases, but the content of cobalt decreased ; fourthly the amorphous structure is transformed to microcrystal structure and polycrystal structure ; fifthly the microhardness and wear resistance of the coating are enhanced ; sixthly coercitive force is reduced, and magnetoconductivity of the coating is increased ; lastly the magnetic intensity of the coating increases with the addition of energy and light rare earth elements such as ce, la and decreases with the addition of heavy rare earth elements such as y. on the other side, when the alloy coatings passes through the heat treatment under the temperature of 250 or 500, their properties will change
結果顯示化學沉積co - ni - b 、 co - fe - b工藝在稀土元素（ ce 、 la 、 y 、 dy ） 、能量（超聲波、磁場）介入后，沉積過程、合金成分、鍍層形貌結構和性能都有顯著變化，表現在：鍍液的陰極極化過電位和極化度降低，沉積速度提高；鍍層的結合力、表面質量改善；鍍層中過渡族元素的含量增加，輕元素硼的含量降低，同時證實了稀土元素與過渡族元素共沉積的可能性；鍍層的顯微結構由非晶態向微晶和多晶態轉變；鍍層的顯微硬度與耐磨性提高，力學性能優化；鍍層的矯頑力降低；磁導率提高；鍍層的磁化強度在能量（超聲波、磁場）和輕稀土元素ce 、 la介入后提高，重稀土元素y介入后降低。 -
