Abstract: The present disclosure provides assemblies, systems and methods of quality control and service inspection for metallic electro-mechanical components. More particularly, the present disclosure provides assemblies, systems and methods of quality control and service inspection for metallic electro-mechanical components (e.g., stator components) utilizing fluorescent agents. The present disclosure provides both (i) surface/assembly designs, and (ii) methods of their inspection. In the present disclosure, fluorescent agents can be mixed with protective and/or added layers to serve as bright contrast media under a light source (e.g., ultraviolet (“UV”) light source). It is noted that in a case of imperfect coating or service corrosion, gaps in reflection can serve as clear indications of either inadequate quality or excessive corrosion-driven degradation of the components.
