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...

Stainless steel is one of the most commonly used materials in most industries. Excellent corrosion resistance of stainless steel is due to the formation of an oxide film on the surface (passive film), which protects the material from continuous corrosion attacks. When subjected to an attack...

Effects of Oxide Additions on the Corrosion Behaviour of Cr2O3 Based Ceramics in High Temperature Supercritical Water Environment
DownloadFall 2012
This investigation is aimed at developing ceramic materials applied in supercritical water, which is being considered as coolant for one of the next generation nuclear reactors. Cr2O3, a primary protective film on stainless steels, was found to be unstable in SCW due to the formation of soluble...

The Role of Sulfur Species in Establishing the Corrosion Reactions in Refinery Metallurgies
DownloadSpring 2016
This thesis is focused on the studying the role that model sulfur-containing molecules have in corrosion reactions on relevant metallurgies. This was done by using a design of experiments where a number of sulfur-based compounds were reacted with various metallurgies. The 8 model sulfur compounds...

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...

The Study of the Corrosion Behavior of Gas Nitriding Treated L80 Steel in Simulated Environment for the Slotted Liners of SAGD
DownloadSpring 2016
The oil sand in Alberta province is mainly extracted by Steam Assisted Gravity Drainage (SAGD) technique which employs the slotted liners as the primary sand screening system. However, the slotted liners made of L80 carbon steel suffer from severe corrosion and erosion problems in the downhole...

The most common detrimental processes that lead to reduction in durability in reinforced concrete elements are shrinkage, sulphate attack and chloride attack. Shrinkage is a dimensional instability chiefly caused by a loss of moisture in the hydrating cement paste. Soluble sulphate ions take part...

Spring 2015
This thesis presents a thorough examination of the corrosion and fouling behaviour of crude oil at refining conditions on industrially applicable heat transfer surfaces. The depletion of light sweet crude oil reserves means that the processing of ever heavier and more sour crude oils is...

Spring 2022
Filiform corrosion (FFC, also known as under-film corrosion) is commonly observed on surfaces of coated aluminum (Al) and aluminum alloys (AA), especially in environments combining marine and industrial atmosphere. The chemical composition of the substrate is believed to play an important role in...
