An exemplary embodiment of the present invention provides an electrostatic metal porous body forming apparatus including: a transfer module transferring a porous body substrate; and a coating module coating a metal powder on the porous body substrate, wherein the transfer module includes a substrate supporter fixing the porous body substrate while the porous body substrate is transferred, and wherein the coating module includes: an electrifier including a first electrode electrifying the metal powder, a second electrode facing the first electrode, a first power supplier connected with the first electrode supplying electricity to the first electrode, and a second power supplier connected with the second electrode supplying electricity electrified with an opposite charge to a charge caused by the electrification of the first electrode to the second electrode, and generating a pulse type of voltage; and a metal powder supplier including a metal powder vessel storing the metal powder therein and supplying the metal powder to the outside, and an outlet separately disposed above or below the porous body substrate injecting the metal powder, and transferring or injecting the metal powder that is electrified and coated by the electrifier.

A transfer and coating apparatus transfers a component from a conveyor to a coating station for application of a coating. The transfer apparatus includes a mast that can move about orthogonal axes in a horizontal plane and a mast having a carriage that can move vertically. The carriage includes a hook that swings about a horizontal axis relative to the mast for movement of the component in the horizontal direction. A sway bar extends between the hook and component to inhibit movement about a horizontal axis. The component is delivered to an upper compartment of a coating apparatus where it can be lowered in to a lower compartment containing coating material. Excess coating material is removed by an array of nozzles in the upper compartment as the component is raised from the coating material.

The assembly (1) for coating workpieces (32) comprises a treatment chamber (1) with a manipulator (24) arranged therein. The manipulator (24) carries a coating device (25) for coating the workpieces (32). The treatment chamber (1) configured as a tank (1) is topped by an exhaust port (3) for exhausting hot gases and/or coating particles. In the interior of the treatment chamber (1) an exhaust hood (33) for channelizing the gases to be exhausted in the direction of the exhaust port (3) is arranged. The exhaust hood (33) together with the pallet (29) are arranged on a shiftable platform (16). The platform (16) together with the exhaust hood (33) and the pallet (29) can be retracted in and extended from the treatment chamber (1). The exhaust hood (33) is arranged on the platform (16) such that when the platform (16) is positioned retracted the exhaust hood is connected to the exhaust port (3).

The invention relates to a separator device (10) for separating particles entrained in a raw gas flow, comprising a frame (12) for receiving at least one separator element (14) and comprising two openings (20, 22) in the frame (12) in an operationally ready state. The frame material which closes the openings (20, 22) before the openings (20, 22) are opened functions as a first and second cover (24, 26), and the two covers (24, 26) can be combined in order to form a pre-separator unit (30) after the openings (20, 22) have been opened and can be arranged on the frame (12) in the region of the inflow opening (20).

Even in a case where a spray nozzle of a solid phase particle deposition device is in motion, flying solid phase particles are efficiently collected. An attachment (1) includes: an engagement part (2) to be engaged with a spray nozzle (130) of a cold spray device (1); and an opening part (3) connected to the engagement part (2) and having at least one opening (3a, 3b) to be connected to a collection section (20) that is configured to collect solid phase particles (30b) which are sprayed through the spray nozzle (130) onto a base material (170) and are not involved in formation of a film on the base material (170).

The invention includes a gas supplier for discharging a gas into a space sandwiched between a substrate and a shielding plate by supplying the gas to a gas discharge nozzle provided in the shielding plate to form a flow of the gas from a central part toward a radially outer side of the substrate. This gas supplier is controlled such that a flow velocity of the gas into a discharge space at a peripheral edge part of the substrate becomes larger than zero.
