The Study of the Corrosion Behavior of Gas Nitriding Treated L80 Steel in Simulated Environment for the Slotted Liners of SAGDDownload
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...
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...
Magnesium remarkably deserves considerable interest from industry especially transportation sector because of its high strength to weight ratio. However, poor wear resistance and low corrosion resistance of magnesium are barriers to extend use of its alloys. Yttrium is one of rare-earth elements...
Investigation of Surface Crack Growth Behaviour Under Variable Pressure Fluctuations in Near-Neutral pH EnvironmentsDownload
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 of Highly Corrosion Resistant and Electrically Conductive Coatings on Metal Bipolar Plates Used in Polymer Electrolyte Membrane Fuel CellDownload
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...
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...
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 EnvironmentDownload
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...
Mechanical, tribological and corrosion properties of metallic materials are of significance to their industrial applications and have been studied for long time. Efforts are continuously made to correlate these properties to more fundamental parameters in order to effectively improve the...
