Spring 2017
Heat distribution measurements in Gas Metal Arc Welding (GMAW) were concurrently measured at the cathode and anode giving increased insight and prediction capabilities. A calorimeter and water cooled cathode were used to determine energy partitions in GMAW for various electrodes, currents,...

Fall 2011
A calorimeter for the deposition of metal during free-flight GMAW was developed for the purpose of measuring droplet heat content in Ni/WC tubular wires. By approximating the thermal gradients within the calorimeter to be second order polynomials the energy transferred to the calorimeter by the...

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...

Oil Upgrading by Molecular Rearrangement and Cracking: A Study Using Model Compounds and Natural Chabazite
DownloadFall 2015
As demand for fuel increases, new technologies that can convert heavy oil and bitumen into light fuels are needed. Natural zeolites have been proven to catalyze reactions that decrease molecular weight, density, nitrogen, and metals content as well as vacuum residue content when mixed with raw...

Protecting Worker Safety in Alberta by Enhancing Hazard Identification and Control for Hazards Associated with Tailings Facilities, Dams, and Systems
DownloadSpring 2019
My research was motivated by a fatality that occurred at an oil sands tailings operation on January 19, 2014, when a worker drowned in an underground cavern which formed under a leaking tailings transport system. At the time of the incident, the organization and workers did not know that ground...

Spring 2016
Non-aqueous extraction technologies are currently being investigated as an alternative to the conventional water based process for extracting bitumen from oil sands. The reduced dependence on fresh water and land for creation of tailing ponds makes non-aqueous technologies a greener alternative....

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...
