Fall 2019
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...

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...

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...

Spring 2011
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...

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...

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...

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...
