摘要:
A process for coating of at least one conformal thin film simultaneously onto the surface of a plurality or batch of substrates having nanoscaled features is provided. The process involves exposing a batch of substrates to a supercritical fluid mixture in a controlled environment, and subsequently heating and cooling the substrate, in the presence of the supercritical fluid mixture, beyond a threshold temperature at which film growth can be enabled to initiate conformal thin film deposition on the surface of the substrate and within the nanoscaled features. The supercritical fluid mixture may be generated in a manner so as to maintain a necessary concentration level of the precursor material to permit sufficient thin film growth within the controlled environment. The supercritical fluid mixture may also be introduced into the controlled environment in a manner which minimizes precipitation or loss of solubility of the precursor material in the mixture. A system of thin film deposition of a batch of substrates is also provided.

A cracking furnace construction includes a firebox (12) defining a chamber (20) having a high emissivity thermal protective layer (18) disposed on at least part of the refractory walls (17) and/or on process tubes (14) disposed within the chamber (20). The coating contains an inorganic adhesive for metal/alloy tubes or colloidal silica and/or colloidal alumina for refractory walls (17) or ceramic tubes, a filler, and one or more emissivity agents. A method of coating the firebox chamber (20) includes preparing the surface of the tubes/refractory walls (17), preparing the coating, and applying the coating to the surface.
摘要:
The invention relates to an apparatus (1 ) and a method for providing the surface of glass (2) with a coating. In the method, at least one liquid raw material (3) is atomized by means of at least one gas-dispersing atomizer (6) into aerosol that is discharged from an atomizing head (34) of the atomizer (6). The drop size of the aerosol discharged from the atomizing head (34) of the atomizer (6) is reduced by changing the hydrodynamic properties of the aerosol flow by means of flow restraints (36), and the aerosol is conducted onto the surface of a glass product (2), where the aerosol reacts forming a coating onto the surface of the glass product (2).

A sheet material dispenser (1) for dispensing portions of sheet material to which a liquid composition has been applied includes a feed mechanism (2) for holding and advancing the sheet material, and a drive mechanism which displaces a carriage along a path of motion. An applicator assembly (8), deployed on the carriage, includes at least one container containing a composition to be applied to the sheet material and at least one applicator for directing a quantity of the composition towards a surface of the sheet material. In preferred cases each container and a corresponding applicator are combined as an interchangeable prefilled dispensing container to facilitate user replacement. A controller actuates the applicator assembly to apply a quantity of the composition to the surface of the sheet material while the drive mechanism carries the applicator assembly along the path of motion.

摘要:
A substrate coating technology for coating a substrate with a coating material having a substantially similar base composition as the material composing the substrate is disclosed. The chemical composition of the coating material is selected to have a melting temperature lower than the melting temperature of the substrate such that the coating material exhibits deep eutectic properties when compared to the substrate. The chemical composition allows the molten coating material to be applied to the substrate by dipping the substrate or pouring onto the substrate.
摘要:
The invention relates to a device and a method for producing nanoparticles, in which method starting materials (105A, 105B) for nanoparticles are mixed at least as liquid droplets (202A, 202B) and, optionally, also as gases and/or vapours with at least combustion gases in a premixing chamber (201). This mixture (212) is separated for liquid drops larger than 5-50 micrometer (214), whereafter the processed mixture (217) is conducted to a thermal reactor, such as flame or plasma, in which the starting materials react and the optional solvents evaporate and generate, through nucleation and/or sintering and/or agglomeration, particles having a diameter of 1 to 1000 nanometres (109).
摘要:
The invention provides a method for forming a tribologically enhanced surface on a workpiece (12). The method includes a step of combining a predetermined material (14) operable to enhance tribological properties with a liquid to form a slurry (16) or a solution (16). The method includes the step of applying the slurry/solution to a surface (10) of a workpiece. The method also includes the step of transforming the phase of the predetermined material with a beam (30) of a laser (18) after the applying step. Transforming the phase of the predetermined material generates a chemical reaction binding the tribological agent with the surface of the workpiece.
摘要:
Es wird ein Verfahren zum Beschichten eines Kunststoffteils (10) mit Lack vorgeschlagen. Bei diesem Verfahren wird in einem Flutschritt eine zu beschichtende Fläche des Kunststoffteils (10) durch Beaufschlagung eines Anflutbereichs (A) der zu beschichtenden Fläche und durch Ablaufen des Lacks über einen Abflutbereich (B) mit Lack versehen. Erfindungsgemäß wird zur Ausbildung einer hohen Verschleißanforderungen genügenden Oberfläche der Anflutbereich (A) vor Ausführung des Flutschritts in einem Sprühschritt mit Lack besprüht, so dass in dem Anflutbereich eine Lackbeschichtung gebildet wird, die aus aufgesprühtem und aufgeflutetem Lack besteht, und in dem Abflutbereich (B) der zu beschichtenden Fläche eine Lackbeschichtung gebildet wird, die nur aus auf geflutetem Lack besteht.
