Abstract
To obtain acceptable adhesion and durability of adhesive bonded structures, anodizing of aluminium alloys in chromic acid or phosphoric acid is commonly used in the aircraft industry. In order to find a non-destructive testing technique to inspect pretreated parts and to gain further understanding, we used some simple techniques to characterize surfaces. Using Transmission Electron Microscopy (TEM) as a tool to characterize surface morphology showed that porous oxides gave the best adhesion quality. The Surface Potential Difference (SPD) measurement was found to be very sensitive to adsorbed dipole layers on surfaces. Surface Impedance (Z) measurements were introduced for determination of the sealing quality of anodic oxides, but can also be used to characterize non-sealed oxide layers. On the basis of experimental data obtained, the effects of several variables in the anodizing process on SPD and Z measurements and TEM morphology are discussed. Also the effects of ageing of anodic oxides by dipping in ambient temperature water are shown.
