Evaluation and Analysis of the Erosion Performance of Flame Spray-Coated Polyurethane Liners
DownloadFall 2016
Polyurethane has excellent wear resistance and is an effective protective liner against erosion caused by the impact of solid particles. However, similar to most polymeric materials, polyurethane has low thermal and electrical conductivity, and this limits its applicability for use in...

Fall 2019
An evaluation of the resistance of two different X70 pipeline steels to hydrogen-induced cracking in severe (pH 2.7 and 1 atm H2S) and intermediate (pH 5.5 and 1 atm H2S) sour service conditions was undertaken. The two steels used in this work, X70-X and X70-B, were selected based on their...

Geomorphic landform design and long-term assessment of tailings storage facilities in the Athabasca oil sands
DownloadFall 2019
In stark contrast to historic mine abandonment, current international best practices in mine reclamation call for geomorphic designs and stability (physical and chemical) for a minimum of 1000 years. Current regulations in Alberta state that post-mining landforms shall be maintenance-free with...

Growth behavior of surface cracks in pipeline steels exposed to near-neutral pH environments
DownloadFall 2013
This study is part of a larger study designed to help a consortium of pipeline operators replace current (very expensive) approaches to managing stress corrosion cracking (SCC) concerns in near-neutral pH (NNPH) environments with mathematical models that predict SCC growth rates. This could...

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...

Fall 2016
Slurry pipelines are widely utilized in most mining operations to transport the raw materials and the tailings. These pipelines typically suffer from high wear rates. For example, in Canada’s oil sands industry, pipeline wear rates of 1 cm/yr are considered representative. To generate and measure...

Investigation of Corrosion and Crack Morphology Behavior under Disbonded Coatings on Pipelines
DownloadFall 2015
Coating disbondment on pipelines is a common phenomenon that leads to exposure of the pipeline metal to the surrounding soil and ground water solutions. The exposure of pipelines to those corrosive environments is associated with development of corrosion and Stress Corrosion Cracking (SCC) on the...

Investigation of Highly Corrosion Resistant and Electrically Conductive Coatings on Metal Bipolar Plates Used in Polymer Electrolyte Membrane Fuel Cell
DownloadSpring 2019
There are apparent technical and economic advantages to replace carbon-based bipolar plates using metal bipolar plates (MBP) for applications in polymer electrolyte membrane fuel cell (PEMFC). However, MBP suffers from corrosion in the acidic environment of PEMFC, and the subsequently formed...

Investigation of Surface Crack Growth Behaviour Under Variable Pressure Fluctuations in Near-Neutral pH Environments
DownloadFall 2017
The goal of this investigation was to study the corrosion fatigue behaviour and mechanisms of surface cracks, semi-elliptical in shape, when exposed to near-neutral pH environments conducive to the environments experienced in the field. To better simulate field conditions, while avoiding the...

Investigation Using Polymer Additives to Mitigate Erosion in Multiphase Turbulent Pipe Flow
DownloadSpring 2019
Long chained polymers were evaluated for their impact on reducing pipe erosion during two-phase flow. The research study was compartmentalized into three categories. One of the components of this study investigated the erosion of different materials in an attempt to find a faster eroding...
