alloy bath造句

"alloy bath"是什么意思   


  1. Technologies were then developed including using of zinc alloy , such as zn - mn , zn - mg and zn - ni alloy baths , and high temperature hot dipping process
  2. 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。
