    摘要:

    利用復合電沉積技術(shù)制備了Ni-金剛石復合鍍層，研究了溶液中微粒懸浮量對復合量的影響，并從兩步吸附、微粒傳輸及界面作用力等不同角度初步探討了金剛石微粒進入鍍層的共沉積過程。結(jié)果表明：在研究范圍內(nèi)，隨溶液中金剛石微粒懸浮量的提高，鍍層中微粒復合量先升高而后緩慢降低。Ni-金剛石復合鍍層的形成與N. Guglielmi的兩步吸附模型及Yeh的微粒傳輸模型不完全吻合。分析認為，金剛石微粒與鎳金屬的共沉積分2個階段，第1階段，微粒依靠攪拌作用傳輸至電極表面，第2階段，微粒在高場強協(xié)助下通過界面作用力的作用逐漸被沉積金屬埋覆

    Abstract:

    Ni-diamond composite coatings were prepared by co-electrodeposition. The effect of the particle content in suspension on the mass fraction of codeposited diamond was investigated. Codeposition process of Ni-diamond system was discussed according to two-step adsorption, particles transmission and interfacial force. The results show that the diamond contents in coatings increase firstly and then decrease slowly with the increasing of particles contents in baths. Co-deposition mechanism for Ni-diamond does not match well with N. Guglielmi’s two-step adsorption model and Yeh’s particles transmission model. Further analysis indicates that the codeposition process of Ni-diamond system could be divided into two periods. During the first period, particles in the baths are transferred to cathode surface by stirring. At the second period, particles are buried in matrix metal by the action of interfacial force with the help of high field intensity of electric double layer.
