Moreover, the phase angle at high frequency is always used to evaluate the corrosion resistance ability of coatings[28–30]. As shown in Bode phase plot (Fig. 6), the phase angle at 105 Hz decreased, and the peak at the high frequency moved to a middle-high frequency region with the erosion process, indicating the gradual decline in the corrosion protection ability of the coatings. One time constant can be observed in the Bode phase plots of the pristine PBA, PBA/α-ZrP-3%, and PBA/α-ZrP-5% coating

During inspection, large areas have to be examined in a small time period and mostly access is

available, malleable and relatively inexpensive. One use of mild steel is on the hulls of seafaring ships. However, corrosion due to the salt water environment and pounding waves is a major problem with the use of steel. Metallic corrosion is estimated to amount to 4% of a developed country’s GDP per year. Therefore corrosion of mild steel and its prevention are major concerns. Metallic corrosion occurs in the presence of oxygen and water. It is the electrochemical degradation of metals to their natural

The majority of pipeline failures are caused by undetected corrosion of the pipe (1). A real-time corrosion detection technique that does not require access to the entire pipeline would allow for maintenance and repairs to be done before a failure occurs, saving time and money, reducing or negating environmental damage, and easing political pressure and social stigma on pipelines. Pipeline failures can relate to each aspect of the STEEP model. When a pipeline fails, it effects the surrounding

were given to the employees of the older generation. In some ways, the writer argues that this change between the generations is positive, as they can make for a more dynamic economy. However, they are also the cause of the article's title, "The Corrosion of Character". The work ethics of the employees are no longer valued. They are taken as

occurs between the sulfur element and oxygen in the air. The acid occurs in the air in the form of Sulfuric acid mists responsible for the corrosion of various metallic and limestone-rich objects. Usually, acid rain results when air containing traces of sulfur dioxide mixes with water (Revie et al., 2011). The acid rain, owing to its PH leads to the corrosion of monuments statues plus memorial, whose main component is calcium carbonate CaCO3. The chief source of sulfur dioxide, in United States,

Introduction: It is widely known that many older reinforced concrete columns may suffer from an inadequate amount of transverse steel reinforcement providing insignificant confining pressure to the concrete core. The seismic performance of these columns may thus be very poor due to their insufficient ductility or low concrete strength. Because the FRP composites owe some of the favorable properties such as high strength-to-weight ratio, the use of FRP composites is nowadays become more common in
