轻稀土萃取分离中稀土总量和分量的同时在线测定 - 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
结果显示化学沉积co - ni - b 、 co - fe - b工艺在稀土元素( ce 、 la 、 y 、 dy ) 、能量(超声波、磁场)介入后，沉积过程、合金成分、镀层形貌结构和性能都有显著变化，表现在：镀液的阴极极化过电位和极化度降低，沉积速度提高；镀层的结合力、表面质量改善；镀层中过渡族元素的含量增加，轻元素硼的含量降低，同时证实了稀土元素与过渡族元素共沉积的可能性；镀层的显微结构由非晶态向微晶和多晶态转变；镀层的显微硬度与耐磨性提高，力学性能优化；镀层的矫顽力降低；磁导率提高；镀层的磁化强度在能量(超声波、磁场)和轻稀土元素ce 、 la介入后提高，重稀土元素y介入后降低。 - Cu - ni sulfided mine complex locate in baimazai of jinping county is sub alkali iron - super iron , it ' s zoning is clear and it ' s ni - cu - co melting first and enrichment , its rare earth is rich in right lean light rare earth , but eu in olive rock is serious to be bad , gd - tb is tittles negative abnormity . above - mentioned show that the mineral is cone from mantle , and didn " t mix with crustal substance , and continent tholeiite magma turning into continent tholeiite emplacement after by surging
