Abstract: Disclosed herein is a method of using surface tension to control the manufacture of candles until a surface tension ranging from 20 to 30 dynes/cm is achieved.

Abstract: A component for a gas turbine engine according to an exemplary embodiment of the present disclosure can include a substrate, a thermal barrier coating deposited on at least a portion of the substrate, and an outer layer deposited on at least a portion of the thermal barrier coating. The outer layer can include a material that is reactive with an environmental contaminant that comes into contact with the outer layer to alter a microstructure of the outer layer.

Abstract: Methods for improving the strength of glass substrates are described. One such method for strengthening a glass disk substrate for a storage device includes immersing at least a portion of the glass substrate in a solution, the solution including a solvent and a coating material selected from the group consisting of NaOH, KOH, and KNO3, removing the glass substrate from the solution, allowing the solvent to evaporate from the glass substrate, and heating the glass substrate at a preselected temperature for a preselected duration, where the preselected temperature is sufficient to substantially melt the coating material and is less than a transition temperature of the glass substrate.

Abstract: A method for hard-material coating or heat treatment of the blade airfoils of blisks for gas turbines includes insulating portions of the blisk other than the blade airfoils against a furnace atmosphere; loading the blisk as a whole into a heat treatment furnace/coating cabinet at the required heat-treatment/coating temperature and partially cooling at least some of the insulated portions of the blisk with at least one of a solid and a liquid cooling medium while the blade airfoils are exposed to the temperature necessary for coating/heat treatment.

Abstract: The present invention discloses discloses a composite PTFE membrane comprising an expanded PTFE membrane as substrate and a sintered porous PTFE membrane on top of it. The porous PTFE membrane on top has porous structure with interconnected channels formed with a sintering process that fuses the PTFE fine powders coated on the ePTFE membrane. Furthermore, the present invention discloses a method for forming the composite PTFE membrane.

Abstract: An inkjet head which is provided with a nozzle plate that is covered with a water repellent film including a Ni-PTFE film, and a plurality of nozzles that are formed through the nozzle plate to eject ink. In this structure, the nozzle plate is subjected to a heat treatment after the Ni-PTFE film is formed on the nozzle plate, and then is subjected to water cooling. The water cooling is performed using cooling water having a temperature ranging from 15° C. through 30° C. after the heat treatment is finished.

Abstract: Method of coating the seam of a welded tube with an adherent metal coating, including applying a nonadherent metal coating to the inside and outside of the welded seam, externally heating the seam area with the seam located in the lower portion of the tube to generally the melting temperature of the coating, then applying a fluid coolant to the external surface to freeze the outer coating while continuing heating to melt the coating on the inner surface and finally quenching. In one preferred embodiment, the tube is heated with an induction heater including a seam coil which first heats the seam area below the melting temperature of the coating and then heated with a full body coil. The coolant may be chilled water or other coolant which is sprayed onto the seam area.

Abstract: A substance and a method for creating a sheath-like protective coating (22). The substance is brought from a solid state into a liquid state, in which it can be sprayed on a surface (20), and after spraying it again returns into the solid state, wherein it forms a coherent body, free of perforations, of a high degree of toughness, whose cohesion is greater than its adhesion to the surface. The sheath-like protective coating (22) can be pulled off the surface (20) as a whole or at least in large sections. The substance is of such a nature that it can be repeatedly liquefied by the application of heat and solidified by the removal of heat. The sheath-like protective coating (22) can be used for the protection of an exterior surface, in particular a pipeline connection (11) at an oil drilling platform. In such a case, it forms a cocoon which encloses the pipeline connection.
