Abstract:
An additive manufacturing process (110) wherein a powder (116) including a superalloy material and flux is selectively melted in layers with a laser beam (124) to form a superalloy component (126). The flux performs a cleaning function to react with contaminants to float them to the surface of the melt to form a slag. The flux also provides a shielding function, thereby eliminating the need for an inert cover gas. The powder may be a mixture of alloy and flux particles, or it may be formed of composite alloy/flux particles.
Abstract:
Processes for impregnating sheets of stone, concrete, or similar material with an impregnating liquid are disclosed. An impregnating liquid in spray form is injected in a vacuum chamber, in which sheets are received, at an amount that gives saturation of the sheets. Apparatus for accomplishing the processes are also disclosed.

Abstract:
The present invention provides a laminate obtained by arranging a composition to be in contact with a rubber, wherein the composition is prepared by blending a polythiol compound (A), an isocyanate group-containing compound (B) and a radical generator (C), and wherein the ratio of the total molar number of the isocyanate group contained in the isocyanate-containing compound (B) to the total molar number of the thiol group contained in the polythiol compound (A) (isocyanate group/thiol group) is from 0.2 to 0.78, and provides a method for producing the laminate. The present invention thus provides a laminate, in which the rubber layer is adhered using at least one of an adhesive or an adhesive sheet capable of strongly adhering a rubber member, especially a vulcanized rubber member, and provides a laminate adhering to a rubber article using at least one of a coating agent and a coating sheet.
Abstract:
Discussed are a roll mold, a method for fabricating the same and a method for fabricating a thin film pattern using the same, which can prevent dimensional variation of the mold and simplify the overall process. The method for fabricating a thin film pattern includes providing a roll mold having a base roller provided with a light source, an adhesive resin layer formed on the base roller, a buffer layer formed on the adhesive resin layer, and a mold surface layer having a groove-protrusion shape formed on the buffer layer; forming a printing liquid on the roll mold or the substrate; and rolling the roll mold over the substrate to form a thin film pattern on the substrate. Also, the mold surface layer and the adhesive resin layer can be cured through light emitted from the light source arranged in the base roller.

Herein, is disclosed a nanocoating technology, which can provide excellent mechanical and barrier performance and flame retardancy, but meanwhile can be easily processed using currently widely adopted processing equipment. The process makes use of a nanocomposite coating composition that includes a nanomaterial, a binder, and a solvent.
Abstract:
A two-coat coating system for producing a two-coat coating, comprising (A) a composition of a transparent radiation-curable or radiation-curable and thermally curable clearcoat material, comprising at least one hydroxy-functional binder, and (B) a pigmented coating composition, the pigmented coating composition comprising at least one blocked, water-soluble or water-dispersible isocyanate.
Abstract:
A curing apparatus for thermally processing thin films on low-temperature substrates at high speeds is disclosed. The curing apparatus includes a strobe head, a strobe control module and a conveyor control module. The strobe control module controls the power, duration and repetition rate of a set of pulses generated by a flash lamp on the strobe head. The conveyor control module along with the strobe control module provide real-time synchronization between the repetition rate of the set of pulses and the speed at which the substrate is being moved under the strobe head, according to the speed information.
Abstract:
A method for applying a coating (4) on a substrate (1), includes: —scanning a laser beam (2) along a line on the surface of said substrate. The method also includes supplying a coating forming material from a supply system (3), the system moving along the same line as the laser beam but coming up behind the laser beam, so that the coating forming material is deposited on a spot which has previously been heated by the laser beam to a temperature above the melting temperature of the coating forming material. Substantially no physical contact occurs between the laser beam and the coating forming material. Preferably, the method further includes a second step of scanning the surface a second time with the laser beam, without adding coating forming material during the second step.
