( 4 ) preliminary investigation of the mechanism of electroless nickel on silicon showed that the catalysis of . silicon surface was acquired by the oxidation of silicon that prompts the deposition of nickel ( 4 )对单晶硅表面化学镀镍的机理进行了初步的探讨，结果表明硅表面的化学镀催化活性可能是由硅的氧化反应促使镍离子沉积成镍核所形成的。
For enhancing the hardness and achieving the surface modification , the superficial nickel plating 45 steel was carried on by laser surface alloying , the result indicated that the microstructure of surface with tiny crystal surpassed the substrate ' s obviously 摘要为提高45号钢的表面硬度，达到表面改性的目的，对表面镀镍的45号钢进行了激光表面合金化。
The improved neural network is applied in study of the relationship between reaction parameters of electroless plating nickel in the process of the metallization of aluminum nitride and the adhesion strength between the metal layer and the substrate 为得到较大的氮化铝金属化层粘附力，运用基于稳健估计的神经网络研究氮化铝金属化中化学镀镍的反应参数与金属层粘附力的关系。
In the procedure , carbon nanotubes were oxidized by nitric acid and then neutralized with naoh to create carboxyl surface groups which were used to adsorb ni ( superscript 2 + ) ions , thereafter the adsorbed ni ( superscript 2 + ) ions were chemically reduced into ni nano - particles as a catalytic center for electroless nickel deposition , all these were further confirmed by infrared absorption spectra and electron microscopic observations 碳纳米管经硝酸氧化和碱中和后表面生成羧基，利用羧基吸附镍离子，之后吸附的镍离子被化学还原为镍的纳米微粒并成为化学镀镍的催化活性中心。
