摘要：
A superhydrophobic conversion film on AA6061 aluminium alloy was prepared via ultrasonication-assistant chemical etching by FeCl3/HCl aqueous solution, KMnO4 passivation,and ultrasonic deposition of trichloro (1H, 1H, 2H, 2H-heptadecafluorodecyl) silane. Field emission scanning electron microscopy (FESEM), contact angle test and Fourier transform infrared spectrometer (FTIR) were used to investigate the morphology, hydrophobicity, and chemical compositions of superhydrophobic conversion film, respectively. The results show that superhydrophobic surface exhibits a high contact angle of 153 degrees and endows the Al matrix promising self-cleaning ability, resistance to acid or alkali erosion, anti-friction and anti-corrosion capability. Compared with the dipping method, ultrasonic preparation of superhydrophobic film on Al alloy surface can not only improve the homogeneity of self-assembly of PFCPS, but also enhance its bonding force with Al matrix and form a superhydrophobic film with good protective performance.
