Case Study: Analysis of Coating Failure on Hinged Steel Boxes Case Study: Analysis of Coating Failure on Hinged Steel Boxes

An investigation was performed to determine the cause of coating failures on several large hinged steel boxes. These boxes were constructed of sheet steel and were allegedly coated with corrosion-resistant coatings. However, after exposure outdoors, much of the paint delaminated and severe corrosion occurred.

Self-cleaning, Odor-reducing, Water-shedding Properties of Titanium Dioxide Photocatalytic Oxidizing Coatings Self-cleaning, Odor-reducing, Water-shedding Properties of Titanium Dioxide Photocatalytic Oxidizing Coatings

A new coating technology developed and commercialized 10 years ago in Japan and just recently introduced to the U.S. offers revolutionary new properties. This new coating technology allows coated surfaces to become self-cleaning of general soil, prevents the formation of a bio-film, has anti-fog and anti-frost properties, reduces odors from indoor spaces in contact with the coated surfaces as well as reduces odors from outdoor air pollution that comes in contact with an exterior surface coated with these coatings.

Current Trends in Cold Spray Technology: Looking at the Future Current Trends in Cold Spray Technology: Looking at the Future

Cold spray is one of the many names for describing a solid-state coating process that uses a high-speed gas jet to accelerate powder particles toward a substrate whereby metal particles plastically deform and consolidate upon impact. The term “cold spray” refers to the relatively low process temperature involved—which is typically much lower than the melting point of the spray material.
