A turbine component surface treatment process includes passing a UV-curable maskant through one or more fluid flow passages, wherein at least a portion of the UV-curable maskant exits the one or more fluid flow passages at an exterior surface of the turbine component, applying a UV light to the exterior surface of the turbine component, wherein the UV light cures at least a portion of the UV-curable maskant exiting the one or more fluid flow passages, and, treating the exterior surface with a treatment material, wherein the portion of the UV-curable maskant cured by the UV light substantially blocks the treatment material from entering the one or more fluid flow passages.

Methods for repairing the conventional physical barrier coating barrier on a component having a damaged portion. Applying a coating on the outer surface of the damaged portion of the component. The coating containing a reactive oxide. Initiating a reaction between the coating and the molten sulfates within the outer surface of the component. The reaction catalytically decomposes molten sulfates at the outer surface of the damaged portion of the component.

A process includes placing a mask over a substrate; delivering liquid film-forming compositions through the mask to the substrate; removing the mask to leave a multilayered raw shape on the substrate; and curing the multilayered raw shape to form the multilayered shaped film product disposed on the substrate. The mask has a delivery surface, an opposite surface and at least one aperture having a design corresponding to the desired shaped film product. The film-forming compositions are delivered through a multistream nozzle. The movement of the mask and the delivery of the first and second liquid film-forming compositions to the mask aperture are controlled to provide a volumetric flow rate of the first and second liquid film-forming compositions to the mask aperture corresponding to the volume of a void. The nozzle is in contact with the delivery surface of the mask.

Soft-matter technologies are essential for emerging applications in wearable computing, human-machine interaction, and soft robotics. However, as these technologies gain adoption in society and interact with unstructured environments, material and structure damage becomes inevitable. A robotic material that mimics soft tissues found in biological systems may be used to identify, compute, and respond to damage. This material includes liquid metal droplets dispersed in soft elastomers that rupture when damaged to create electrically conductive pathways that are identified with a soft active-matrix grid. These technologies may be used to autonomously identify damage, calculate severity, and respond to prevent failure within robotic systems.

Systems and methods for protecting threads of metal pipes while coating the metal pipes with a protective coating are disclosed herein. Innovative metal couplings are used to protect the threads while a protective coating is applied to the metal pipes. The couplings are reusable and result in multiple efficiency improvements over previous methods and systems. Benefits include elimination of plastic caps and reduced waste, improved flowthrough in the powder coating process, more efficient thermo transfer in the thermal chamber, and an increase in the overall capacity of the powder coating operation.
