Abstract
A closure member is configured for use in a valve. These configurations may have a coating or conformal layer that may cover most, if not all, of the underlying material. This layer may include pre-propagated cracks that form due to thermal cycling prior to use in service. These pre-propagated cracks act as stress relief to accommodate for possible thermal stress that occurs due to different rates of thermal expansion between the underlying closure member and the coating. In one implementation, the layer may include a crack profile, which is engineered to direct formation of the pre-propagated cracks as well as to arrest crack development to a certain depth to maintain at least some integral layer of material over the underlying plug. This feature can extend service life of the plug, particularly in highly-erosive process fluids, like particle-entrained fluids commonly found in hydrocracking or refining operations.
