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 andor for the protection of metal surfaces against corrosion and wear.
