Abstract College of Mechanical and Electrical Engineering, Shaanxi University of Science & Technology, Xi’an 710021
Mixed acid treatment of carbon fiber(CF) was first carried out, and then Al coating was plated on CF surface by adopting AlCl₃-NaCl-KCl ternary inorganic molten salt system. The morphology and properties of the treated CF were characterized, and the effects of diverse plating processes on the thickness, morphology structure and properties of the coatings were studied. It could be found from the results that there was an obvious increase in surface roughness and specific surface area of CF after the treatment by mixed acid. Meanwhile, the wettability of CF surface was improved, and the tensile properties of CF showed a slight increase. Furthermore, the electroplating process parameters exerted a notable effect on the thickness and morphology of the coating. With the increase of the plating time, the coating thickness increased. In addition, morphology and structure of Al coating exhibited distinct changes when the current density varied. Uniform and compact coating could be achieved under the plating duration of 3 h and current density of 35 mA/cm².
