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...

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...

Road Erosion, Sediment Delivery, and Consequence in the Simonette Watershed West-Central Alberta
DownloadSpring 2022
Gravel and dirt resource roads in the Alberta foothills are critical economic infrastructure, used to explore for, manage, and extract natural resources from this region. Resource roads are also known to add sediment to nearby streams and rivers, causing habitat stress for fish. Understanding...

Fall 2020
Sediment in storm sewers attracts increasing attentions in recent years due to two major issues including the sewer blockage and the environmental contamination. Pollutants attached to fine sediment surface may adversely affect aquatic life and natural water bodies. Excessive sediment deposition...

Surface modification of zirconium implants via electrochemical anodization and wet chemical techniques
DownloadFall 2011
Metals such as titanium (Ti) and zirconium (Zr) have been widely applied in the orthopaedic and orthodontic field for construction of joint replacement prostheses and teeth implants due to their lower cytotoxicity, excellent mechanical properties, and corrosion resistance. However, the current...
