Abstract
The objective of this proposal is to develop surface preparation method for aircraft grade aluminum alloys for adhesive bonding using sol-gel processes. Low temperature phase y-Al2-O3 coatings will be prepared on aluminum alloys by sol-gel processing. The problem of drying and sintering of gels on aluminum alloys will be solved by rapid thermal processing (RTP). RTP involves high temperature (1000-1200 degrees C) exposure for a very short (5-20 sec) period of time, so that the substrate temperature may not exceed the thermal limit of processing aluminum alloys. The Phase I goal is to demonstrate the process feasibility by depositing anhydrous alumina coatings. The coatings will be characterized for chemical composition, morphology, thermodynamic stability, hydrolytic stability and bondability.
