Localized Surface Modification of High Strength Aluminum Alloys using Cold Spraying and Friction Stir Processing
DownloadFall 2021
Dimensional restoration and repair methodologies for cold-worked aluminum (Al) alloys are very limited due to strength degradation that occurs during heat application in the process. For example, friction stir processing (FSP) is a well-documented repair methodology for various alloys, but it...

Towards optimization of thickness, hardness, and porosity of low-pressure cold sprayed WC-Ni coatings.
Download2021-01-01
Jibran, Wania, Hogan, James D., McDonald, André
In this study, a 33 full factorial design methodology was used to analyze the effects of spray parameters on the thickness, hardness, and surface porosity of low-pressure cold-sprayed WC-17Ni coatings. Three levels were selected for the spray parameters included in the design which were the...
