Spring 2019
This project investigated the abrasive wear problem that commonly occurs in slurry pump impellers. The manufacturers’ stock impellers were replaced by samples with the same geometry and fabricated using rapid manufacturing technology (3D printing technology). Soft materials which are often used...

Microstructural Characterization of Chromium Carbide Overlays and a Study of Alternative Welding Processes for Industrial Wear Applications
DownloadSpring 2014
Microstructural features of chromium carbide overlays (CCOs) were examined in this work. It was found that the microstructures can contain unmelted alloy powders. It was also shown that the structures of the primary M7C3 carbides are long hexagonal rods. Change in the microstructure from the top...

Studies on the improvement in wear resistance of WC-Co composites by adding a pseudo-elastic TiNi phase and relevant issues
DownloadSpring 2012
In this study, pseudo-elastic TiNi alloy was added as a second phase to the Co matrix of WC-Co composite, which has found many applications in forms of coating, hardfacing overlay and bulk against wear. It was demonstrated that the added TiNi phase markedly enhanced the wear resistance of...

Spring 2012
This work is focused on development of tungsten carbide-based materials as alternative anodes for direct utilization of methane in solid oxide fuel cells (SOFCs). Not only were the capabilities of the anodes highlighted, but the challenges were also stressed. First, the impact of porous support...

Fall 2011
Various pressures of compressed air were introduced into the flame spraying torch and the protective coatings of nanostructured and conventional titania (TiO2) were deposited on low carbon steel substrates. Performance of the coatings was studied using scanning electron microscopy (SEM), hardness...
