The invention relates to a method for surface treating a substrate (28) by means of an electrical corona discharge, wherein aerosols (5) are sprayed into discharge area defined by an active gap formed between a corona electrode and the substrate (28) during the discharging, designed such that the aerosols (5) are sprayed substantially opposite the direction of gravity.

The invention eliminates defects generated in a metal filling a through hole of a printed board by changing an angle at which a plating solution is sprayed or by changing a posture of the printed board at a time point in a process of precipitating the metal from the plating solution and filling the through hole with the precipitated metal while the plating solution or air bubbles are being sprayed onto the printed board.

An apparatus for manufacturing a display device and a method of manufacturing a display device is disclosed. In one aspect, the apparatus includes a guider configured to guide a substrate on which a display portion is formed, a plasma sprayer configured to be spaced apart from the display portion and configured to spray plasma onto the substrate and a mask configured to be arranged over the substrate and cover the display portion. The mask includes a body portion configured to face the display portion and a protrusion portion formed at an end of the body portion and configured to extend towards the substrate.

A first constant velocity joint is equipped with a cup part made of a light alloy. First ball grooves that receive a torque from torque transmitting members are formed on an inner wall of the cup part. A high hardness layer made of ceramic or cermet as a principal component thereof is formed on an inner surface of the cup part including at least inner surfaces of the first ball grooves.

A thermal sprayer system includes an injector conduit in communication with an injector and a first valve for selectively directing a coating fluid through the injector conduit. A flush fluid conduit is in communication with the injector conduit for directing a flush fluid through the injector conduit. A pressurized air conduit is in communication with the injector conduit for directing a pressurized fluid through the injector conduit.

A method for applying anti-gallant coating to metal parts utilizes an ultrasonic sprayer driven by a precise manipulation device such as a robotic arm for high efficiency and precision. The method does not require masking adjacent or nearby metal parts, decreases time and money spent applying the anti-gallant coating, and is environmentally friendly.

A method for manufacturing a component is provided. The method includes providing one or more notches on a surface of the component. Further, depositing a coating on the surface to provide a thickness of the coating on the surface, is performed. The method also includes removing, at least partially, the coating from the surface such that the thickness of the coating over the notches is different from the thickness of the coating on the surface adjacent to the notches.

Transportable modular coating systems include a first transportable coating module comprising at least one first removable wall, a second transportable coating module comprising at least one second removable wall, wherein the first and second transportable coating modules are joinable when the first and second removable walls are removed, and a plurality of coating components fixed within the first and second transportable coating modules that combine to create a coating operation. The transportable coating module further includes a transportable control module that comprises a control system that operably connects to the plurality of coating components to operably control the coating operation.
