Introduction When applying coating system to structures such as bridges, tanks, and pipelines the main goal is to apply a continuous film to help prevent structural deterioration throughout the life of the structure. Unaddressed discontinuities can result in undercutting corrosion of the substrate, where the integrity of the structure could be prematurely compromised. This article

When a coating system fails prematurely, it is rarely because of the coating itself. Either the surface preparation was inadequate, the surface was contaminated, or the coating was mixed or applied incorrectly. As the old adage goes, a house is only as strong as the foundation it is built on. When it comes to coatings,

Installation of a coating to a cathodically-protected pipeline or structure without first testing its resistance to cathodic disbondment can result in catastrophic failure of the coating. However, there are over twenty international standard test methods to evaluate a coating’s inherent resistance to cathodic disbondment; each with its own set of parameters and materials, which can
Background Ergonomics is a field study that involves the application of knowledge about physical, psychological, and biomechanical abilities and limitations of the human body. This knowledge is applied to the planning, design, and evaluation of work environments, jobs, tools, and equipment to improve worker performance, safety and health. In layperson terms, ergonomics is fitting the

High temperature-resistant coatings are used in a variety of industries and markets to prevent corrosion of steel subjected to extreme temperatures while in service. There are several testing protocols that are used to evaluate the performance of these coatings; however, performance comparisons are challenging since there is little uniformity or consistency of the test methods.
For clear, magnified images and quick, targeted analyses of elemental composition, SEM-EDS is the method of choice. Introduction. A scanning electron microscope (SEM) can be used to examine samples at very high magnifications – up to 1 million times! The analysis of coating failures with an SEM typically only uses magnifications up to 10,000X, however,
This 24- minute podcast also features Ken Trimber as moderator, while Doug Reardon advocates total shop painting and John Todd promotes shop painting with field finish coating. Scenarios are posed by Trimber as Todd and Reardon take turns providing support for their approaches while divulging plenty of information on the subject. A podcast breakdown is
