Aluminum alloys are widely used in engineering structures and components due to their light weight and excellent mechanical properties. However, the alloying elements which contribute to the good mechanical properties also make the alloy prone to localized corrosion. One of the most common and economic approaches to protect Al alloys from corrosion is to apply coatings as protective layers. For example, powder coatings and magnesium-rich primers (MgRP) are both widely used for the corrosion protection of Al alloys.
This paper on the use of Fourier transform infrared spectroscopy and instrumental determination using algorithm-based comparison of spectra is comprised of an orientation to the basics of instrument use and sample preparation, followed by a review of test programs and results of instrument-based spectra comparisons of numerous industrial coating types. The chemical molecular bonds associated with each coating type used to generically identify the coating types will be reviewed as background information.
By establishing a holistic program that incorporates workforce training, the nation's first baccalaureate degree in Corrosion Engineering, and world-class research in corrosion and materials performance; The University of Akron (UA) is establishing a program that will create a pipeline of critical resources that will ensure that future investments in equipment and infrastructure revitalization are designed and implemented in a manner that minimizes the impact of corrosion and thus reduces the life-cycle cost to sustain those assets.
The paint and coatings industry has witnessed significant change over the past 50 years. These changes have been driven by many factors including VOC mandates, safety concerns, advanced polymers and new demands of the end users and materials. One of those changes was the introduction of desiccant dehumidification to assist in the blast and coatings process of liquid storage tanks in 1983. The ability to indefinitely hold a blast by providing a dry climate mechanically set off the beginning of a technology that would continue to advance for years to come.
Existing US Navy Coefficient of Friction (CoF) meters are insensitive and cannot differentiate surfaces which have obvious differences in nonskid CoF. A new CoF meter, the m-Deck, was evaluated to determine CoF measurement effectiveness and temperature sensitivity. Both laboratory and field testing were performed over various nonskid systems at numerous temperatures. The results indicate that the m-Deck has significant temperature dependence, but also a high degree of accuracy. The collected data is used to establish acceptance criteria for newly installed nonskid.
