Potential Use of Cold Sprayed Nanostructured Aluminum for Corrosion and Wear Protection
Abstract
FUTURE WORK: ARL will develop cold spray parameters for the non-cryogenically milled AA5083 powder * Evaluation of the deposits will be carried out, i.e., metallography, XRD, micro-hardness * US Naval Academy will evaluate cold sprayed nanostructured deposits for corrosion resistance and fatigue performance * wear testing will also be carried out. SUMMARY: Bulk nanostructured Al alloys show a higher resistance to localized corrosion * Cold spray process was successfully used to deposit quality nanostructured Al alloy coatings * Cold sprayed Al-Co-Ce onto Al alloy samples showed superior fatigue resistance over ALCLADed and substrate-only samples * Cold sprayed n-Al alloys have potential for the repair of localized damage of aluminum structures and/or for the protection of metal surfaces against corrosion and wear.
