Abstract: The present disclosure relates generally to systems, devices and methods for disinfection of space and equipment. In particular, the present disclosure relates to systems, devices and methods, such as rolling enclosures, which use light sources, such as ultraviolet (UV) light, and more specifically UV-C light, to disinfect larger scale equipment or spaces. Systems and methods of the present disclosure are particularly useful in medical facilities for treating medical equipment or spaces, where the prevalence of pathogens requires frequent disinfecting.

Abstract: A component suitable for use in a gas turbine engine. The component includes a substrate defining a surface of the component and has a first surface and a second surface. At least one aperture extends through the substrate from the first surface to the second surface, and has a first open area. The component has a first coating on at least one of the first surface and the second surface adjacent to the at least one aperture. The component also has a second coating overlying the first coating adjacent to the at least one aperture, such that at least a portion of the first coating is exposed adjacent to the at least one aperture. The first coating defines a second open area which is smaller than the first open area.
