Evaluating Coatings for Immersion Service via Electrochemical Activity

Evaluating Coatings for Immersion Service via Electrochemical Activity
Available for download

Industry constantly seeks improved methods to evaluate protective coatings. In immersion service, protective coatings act to reduce electrochemical activity at the metal/coating interface. Tracking this activity via the use of segmented panel testing appears to offer additional insight into coating performance that may aid in coating design and predicting longer-term performance.

Industry constantly seeks improved methods to evaluate protective coatings. In immersion service, protective coatings act to reduce electrochemical activity at the metal/coating interface. Tracking this activity via the use of segmented panel testing appears to offer additional insight into coating performance that may aid in coating design and predicting longer-term performance. The data generated also suggest that many currently used observations, such as degrees of surface rusting, are not as significant as presumed. The paper recommends some additional performance standards for predicting coating performance.

The Occupational Safety and Health Administration (OSHA) defines abrasive blasting as “using compressed air or water to direct a high-velocity stream of an abrasive material to clean an object or surface, remove burrs, apply a texture or prepare a surface for the application of paint or other type of coating.” OSHA regulations governing General Industry, Construction, and Shipyards mandate the use of abrasive-blast respirators approved by the National Institute for Occupational Safety and Health (NIOSH). Blast respirators are Type-CE supplied-air respirators, commonly known as “blast helmets.” This article will review and explain the components and the requirements pertaining to the use of these respirators.

The Effect of Four Commercially Available Steel Decontamination Processes on the Performance of Internal Linings

Internal linings used for corrosion protection often have to perform under severely corrosive environments. One major concern regarding coating performance is the negative effect of soluble salts on the steel substrate at the time of lining application, particularly for higher temperature lining applications. These salts impact the ability of the applied coating systems to protect the steel in several ways including osmotic coating blistering, promotion of under-film metallic corrosion and lining disbondment.
