The exposure of certain carbon steels to sour environments can result in severe hydrogen induced cracking (HIC) damage in the oil and gas industry. Current mitigation techniques in this field have low reliability or are not able to provide long-term protection against such damage. Recent advancements in thermal spray technology have resulted in...

Accelerated tests have been commonly used by the marine coating industry to evaluate the performance of a coating in a short duration of time. Replicating natural exposure in an artifi- cially simulated manner is a challenging task due to the various factors that induce corrosion in the natural environment. Continuous salt spray testing is a...

Trivalent chromium (Cr(III)) is one of the most promising non-toxic replacements for hexavalent chromium (Cr(VI)) coatings in the steel packaging industry. The application of a chromium layer to packaging steel is essential for providing a protective layer on the steel packaging’s external surface area, which prevents corrosion during its use....

Due to their simple structure and the possibility for in situ doping, light emitting electrochemical cells (LECs) are shaping up to be a cheap and easily produced alternative to LEDs. To date, little research has been done to combine the luminescent properties of colloidal quantum dots (QDs) with the LEC concept. In this thesis, steps are taken...

Rapid industrialization and use of carbon based fuels has caused a drastic increase in the atmospheric CO<sub>2</sub> levels in the last few decades. The rising anthropogenic CO<sub>2</sub> levels pose a significant threat to the environment as evidenced by the increase in the mean global temperature levels, and the rising ocean levels. To...

Hexavalent chromium has been the industry standard for corrosion protection for many years. Its unsurpassed active corrosion inhibiting capabilities, its incredible versatility and its economic benefits made it a popular all-rounder. Nowadays the widely known toxic and carcinogenic nature have restricted its use within the European Union. More...

Water as a coolant for industrial products or processes is widely used. Efficient operation of Open Recirculating Cooling Water Systems (ORCWS) relies on controlled cooling water conditioning programs that prevent corrosion, fouling, scaling and microbial growth. Water intensive industries feel greater pressure to decrease their water demand as...

Because of a series of predominant properties, copper and copper alloys are used nowadays in the production and manufacturing industries. Amongst all available copper alloys, brass, with a relative low cost, is one of the most common materials with a wide range of applications, such as heat exchangers and maritime industry. Corrosion is a common...

To reduce the cycle times required for grit blasting prior to the application of an epoxy coating on the pipelay vessel an alternative method for the surface preparation is required. The method should be effective in material removal and ensure perfect adhesion of the organic coating to the carbon steel surface. In this study, a well-established...

Basic oxygen furnace (BOF) slag is a by-product of the steel conversion process in a basic oxygen furnace. A previous study at Tata Steel in Ijmuiden has discovered the inhibition effect of BOF-slag on the corrosion of cold rolled- and hot-dip galvanized steel. This inhibition effect and its mechanism was studied in this work and its was...

With the demand for cleaner energy rising in the future, petrochemical companies such as Shell need to stay innovative and competitive in supplying energy resources such as natural gas. Highly sour gas fields, which contain carbon dioxide (CO2) and a large amount of hydrogen sulphide (H2S) alongside the natural gas (CH4), are considered to be...

MHTs (MHT-p, MHT-N) represented superior corrosion inhibition effect against chloride induced pitting corrosion in simulated concrete pore solution when compared with the pure inhibitors (pAB, NaNO2). Among them, MHT-p exhibited a better improvement of inhibition effect than MHT-N. This result is probably caused by the bigger ion exchange...
