Coating thickness is one of the most important parameters influencing durability of a protective coating system. As a general rule-of-thumb, the thicker the coating, the greater the protection. But is there any upper limit to this general rule? This paper looks at durability figures of common protective coating systems for atmospheric and immersion exposure as a function of dry film thickness.

Neptune Bulk Terminals in Vancouver, British Columbia needed to re-coat two of its ocean-going Potash Ship Loader conveyors within a 27-day window to prevent interruption of international ship loading schedules. The contractor elected to use ultra high pressure water jetting (UHPWJ) for the steel surface preparation rather than the sand blast medium used on the previous loader conveyors. This required innovative desiccant dehumidification equipment to facilitate rapid drying of the steel upon completion of the UHPWJ work due to an increased moisture load.
Water chemistry definition in nuclear fusion research experiments is under development. Many nuclear fusion experiments, such as the Italian Divertor Tokamak Test Facility (DTT)[1], the Korea Superconducting Tokamak Advanced Research (KSTAR) [2] and Japan Torus-60 Super Advanced (JT60SA) [3] reactors consider the use of enriched boric acid (up to 95% 10B) in water to shield the superconducting coils by neutrons generated from nuclear fusion reactions in the plasma chamber.
TOL corrosion is reported to occur in large diameter wet gas pipeline in stratified flow conditionsdue to low fluid velocities1. With increasing distance from the inlet, the wet gas pipeline becomescooler as it loses heat to the environment. Such cooling causes water, hydrocarbon, and otherhigh vapor pressure species to condense on the pipe wall. The upper part of the pipe willconstantly be supplied with freshly condensed water while the less corrosive water saturatedwith corrosion products will be drained along the pipe wall to the bottom of the line.
Since ductile iron (DI) pipes generally cannot be galvanized, inorganic zinc (IOZ) coatings can be considered to provide sacrificial corrosion protection in harsh atmospheric exposures, such as marine environments. The unique application of IOZ coating system provides an excellent cost-effective, long-term protection of atmospherically exposed DI pipes.
The 2014 US bridge inventory lists over 610,000 highway bridges. Industry experts believe that the cost of maintaining those bridges for repairs due to corrosion is at least $30 billion annually. Bridge owners do not have the resources to maintain bridges in good condition. New bridges are being constructed, at the rate of approximately 3,000 nationally each year. Those new bridges must not pose additional maintenance burdens on the already inadequate bridge maintenance budgets.
The Bureau of Reclamation (USBR) is currently investigating the feasibility of using foul-release coatings to mitigate impacts caused by macro-fouling organisms such as zebra and quagga mussels. Durability of these coatings must be considered as a factor in determining overall life cycle costs. To this end, the Bureau of Reclamation has developed testing protocols to evaluate the durability of foul-release coatings with respect to abrasion, erosion resistance and the ability to overcoat existing equipment.
Corrosion inhibiting admixtures has been initially used as concrete additives to inhibit chloride induced corrosion of rebars in the late 1970`s. The first chemistry introduced to the market was based on Calcium Nitrite chemical composition, which in performance is classified as anodic inhibitor, protecting the anode site of the corrosion cell. Calcium Nitrite inhibitor`s mechanism of protection depends on the interference with the chloride complexing process by oxidizing the more easily attacked Fe2+ form of iron to the more stable Fe3+ form.
