Abstract:

Waste-fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work the high temperature corrosion of candidate superheater alloys have been investigated by detailed laboratory studies and controlled field exposures in full-scale boilers. In a laboratory study the detrimental effect of gaseous hydrochloric acid (HCl) on three different ground surface and preoxidised austenitic stainless steels was investigated. Exposures were conducted in an environment comprising N2-10O2-5H2O-0.05HCl at both 400 °C and 700 °C. A positive effect of preoxidation is

Abstract:

The valuable properties of silver can be diminished or destroyed because the metal is susceptible to corrosion by certain atmospheric species. Particularly aggressive is H<SUB>2</SUB>S which 'tarnishes' the surface by reacting to form Ag<SUB>2</SUB>S. There have been many attempts in the past to produce a tarnish resistant silver either by surface coating or bulk alloying; none have so far proved to be entirely successful. This thesis describes the production of surface coatings on silver by inert and reactive sputtering for application in the Silversmithing Industry. They should, therefore, b

Abstract:

The polarization performance of two types of commercial galvanic point anodes for protection of reinforced steel around patch repairs was investigated. Experiments included measurement of the polarization history of the anode under constant current impressed by galvanostatic circuits and in reinforced concrete slabs. The tests revealed, for both types of anodes, a potential-current function (PF) indicating relatively little anodic polarization from an open circuit potential at low current levels, followed by an abrupt increase in potential as the current approached an apparent terminal value.

Abstract:

Corrosion can take place as chloride ions accumulate above a critical concentration (CT) at the surface of a reinforcing bar inside concrete in marine service. The initiation of corrosion can be delayed by polarizing the steel cathodically, which is known to increase the value of CT. That effect is the basis of the cathodic prevention (CPrev) method to control corrosion of reinforcing steel in concrete. However, concrete cracks are a common occurrence and at cracks, the buildup of chloride ions is accelerated to the extent that CPrev may be less effective. The findings from an ongoing investig

In this work, I aim to clarify the mechanism that allows steel to attain higher chloride threshold as it is cathodically polarized. Specifically, I seek to provide empirical information on whether an intrinsic (predominantly interfacial effects of polarization) or an extrinsic (predominantly concentration changes due to polarization) mechanism may be dominant in the beneficial effect of polarization. I carried out this experiment with 12 identical concrete specimens, each with a cast-in steel plate, constantly exposed them to high-chloride environment. The specimens were divided into 4 triplic

There are numerous forms of corrosion that have a negative effect on HSS, as well as material properties that need consideration when designing HSS preventive measures. Understanding corrosion and providing proper preventive measures is crucial for HSS. Proper maintenance and repair of these

Abstract:

Scaling and corrosion cost industries all over the world millions of rands each year. Chemical treatment of water to prevent scale is expensive and can be hazardous. As a result industry is always looking for new, cheaper alternate methods of reducing scale. One such method is magnetic water treatment. Magnetic water treatment involves passing hard water (the main cause of scale) through a magnetic field. This method favors the precipitation of calcium carbonate in the form of aragonite instead of calcite. Aragonite is a softer, less tenacious material that does not adhere to the walls of pipe

碩士<br>國立臺灣科技大學<br>營建工程系<br>92<br>Corrosion of bridge structures is a problem faced by countries throughout the world. Taiwan is no different; with narrow topography metropolitan and industrial areas have been forced to intersect with coastal regions creating a complicated corrosion problem. Especially in coastal regions, bridges are directly exposed to a harsh corrosive environment creating challenges for the durability of bridge structures. This research performs an analysis and examination of the current corrosion status of bridge structures in Taiwan. A survey and analysis of

碩士<br>國立臺灣海洋大學<br>河海工程學系<br>102<br>Steel corrosion, especially in high chloride environments, has become the prime factor affecting concrete durability. In extreme corrosive environment (like in an oceanic climate or high humidity environment) for 5 to 15 years, steel is highly suseptible to becoming corroded, cracked by expansion, and finally broken if not repaired in time. To solve the problem, researchers have developed a series of protecting and repairing methods, one of them is the steel rust transformer. This study seeks to understand the effect rust coated steel has on different environ

Abstract:

Many Canadian cities are faced with the problem of an aging and deteriorating iron water distribution network - pipe breaks, leakage, and/or aesthetic water quality problems. Public confidence in municipalities’ ability to deliver safe, clean drinking water to customers has been eroded, especially in areas of water distribution networks receiving coloured water events that result from the internal corrosion of aging iron watermains. Cement mortar lining is one of the most widely used non-structural watermain rehabilitation methods for the prevention of coloured water events due to internal i

碩士<br>國立中興大學<br>材料科學與工程學系所<br>103<br>The Mg alloy applications for the automotive industry have received attention due to its light weight. Furthermore, magnesium alloys have high specific strength and low density. However, it has a poor corrosion resistance, and strength decreased rapidly when a fire occurs. Therefore, this study will improve corrosion resistance and thermal properties of AZ91D by the thermal barrier-corrosion prevention spray coating. In this research, the CaCO3/Ca3(SiO4)O-base powder mixed with SiO2 and Mg-Fe LDH powder to form a paste which sprayed on the surface of magnes
