Within ongoing work, Canada’s Nuclear Waste Management Organization (NWMO) is demonstrating that copper coatings can be developed as viable corrosion barriers for used fuel nuclear containers, emplaced in a deep geological repository. As a means of assessing container design and feasibility, coated samples, manufactured via cold spray and electrodeposition have been produced and characterised. ...

Mg alloy AZ31 is an attractive candidate for coronary artery stents, as it possesses excellent biocompatibility in human body and good mechanical properties. However, AZ31 magnesium alloys generally have poor corrosion resistance in the body environment. This paper reports on the early stages of an investigation into the corrosion mechanism and the morphology of corrosion of AZ31 in simulated b...

The corrosion resistant coatings used conventionally are susceptible to degradation, leading to pitting corrosion. This report summarizes the corrosion resistant nature of thin films of Cu-TiO2 coated on mild steel, in different corrosion environments. Nano meter thick (100nm, 125nm, 150nm) composite coatings were coated on steel substrate by RF magnetron sputtering technique. The required targ...

A series of stress corrosion experiments were performed on 12 pultruded glass fiber composite materials (two fibers in six different matrices) commonly used in high voltage composite insulators. In this study two types of glass fibers were investigated, namely Eglass and ECR-glass. The tests were performed in nitric acid solutions (pH 1.2) using constant K I specimens that were specifically des...

Describe various geographical environments in terms of their atmospheric corrosivity Summarize the main factors causing atmospheric corrosion Explain how these factors are measured Examine how the safety introduced by the massive usage of deicing salts has modified the corrosivity of road environments Design a testing program to establish the corrosivity map of a given site or even a country re...

Copper alloys are widely used in the manufacturing of heat transfer applications, this due to their excellent heat transfer properties. Copper contamination is one of the serious industrial problems in the boiler feed water system. This contamination commonly resulted from copper corrosion reactions in boiler feed water environment. The best way to reduce the copper contamination is by improvin...

In this study, the pitting type of corrosion growth characteristics, fatigue crack initiation and propagation behavior; axial fatigue tests were carried out on precipitation hardened martensitic Custom 450 steel in the air and 3.5wt% NaCl solution. Using the ratio of the depth to the half-width of the pits; (a/c)= 1.5±0.2 the corrosion pit depth growth law was obtained as a function of stress a...
