Abstract


The study is modified aluminum alloy surface by two methods that hydrazine hydrate solution treated and plasma chemical vapor deposition (with HMDSO as monomer), to improve the bonding strength between aluminum alloy and plastic injected directly, and enhance aluminum alloy corrosion resistance. The effect of both methods treated aluminum surface were studied respective.Through the related performance tests for aluminum of before and after treated by hydrazine hydrate solution and plasma chemical vapor deposition, the bonding strength between aluminum alloy and plastic and aluminum anti-corrosion were studied systematically. Moreover, contact angle measurement, SEM, IR, and EDS were used to characterize surface properties of aluminum alloy such as morphological structure and chemical composition. The bonding strength and the corrosion resistance were analyzed by a universal testing machine and electrochemical workstation respectively.The result showed that the aluminum alloy surface would uniform micron and nano-scale pits and a layer of solid oxide film after treated by hydrazine hydrate solution, and the aluminum surface to form a layer of SiOx film ranged closely by plasma polymerization deposited with HMDSO monomers. The surface properties of the treated aluminum has been greatly improved, the bonding strength between aluminum alloy and plastic directed injection molding increased by 6 times, the standard electrode potential increased by 0.3V, the corrosion current decreased by an order of magnitude, and the capacitive loop radius of electrochemical impedance spectroscopy (EIS) has little change with the corrosion time longer, indicated that the corrosion resistance of aluminum alloy have been greatly improved.
