Application of Thermally-Sprayed Coatings as Heat Tracers for Carbon Steel Pipes to Mitigate the Effect of Ice Accumulation and Freezing Damage
DownloadSpring 2020
The bursting of pipes due to freezing of contained liquid is considerably costly in industrial applications, resulting in over $4 billion in damage over the last decade alone in the United States. This doctoral research program attempted to study the root cause of the failure of pipes due to...

Changing Landscape Coatings for Bioactive Bone Fixation Implants via Flame Spray Deposition
DownloadFall 2013
Owing to the bio-inert nature of load-bearing alloys and the brittle nature of bioactive materials there is a need to develop a composite bioactive material suitable for load-bearing applications. To fulfill this need, a new composite coating of a load-bearing alloy and a resorbable bioactive...

Fabrication of WC-based Metal Matrix Composite Coatings via Low-pressure Cold Spraying for Enhanced Surface Properties
DownloadFall 2013
A low-cost, low-pressure cold spray unit was used to fabricate tungsten carbide (WC)-based metal matrix composite (MMC) coatings. A variety of coatings were fabricated and characterized. Scanning electron microscopy (SEM), coupled with image analysis, Vickers micro-hardness, and X-ray diffraction...

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...

On the Mechanical Properties and Failure of Low-Pressure Cold-Sprayed Tungsten Carbide-Nickel Metal Matrix Composite Coatings
DownloadFall 2019
Tungsten carbide-Nickel (WC-Ni) metal matrix coatings (MMC) were fabricated using a low-pressure cold spray unit. The coatings were designed according to 50, 71, and 92 weight percentages of WC in the feedstock powder. These coatings were subsequently prepared for uni-axial quasi-static tensile...

Quantification of Performance of Wildfire Chemicals using a Custom-Built Sensible Enthalpy Rise Calorimeter
DownloadSpring 2018
A simple and effective laboratory experiment was developed to investigate the relationship between coverage level, fuel load, and fire intensity for different vegetative fuels. The experiment consisted of a fuel bed consisting of known quantities of fuel load and applied coverage, and an...
