Universal plasma plant “UPU-10” is designed for deposition of metal and ceramic powder materials, as well as materials in the form of wire, on the surfaces of parts and assembly units using the plasma spraying method and allows the application of wear-resistant, corrosion-resistant, friction, insulating and other special coatings from two powder dispensers .

 “UPU-10” plant deposits the coating using a plasma jet by depositing particles of sprayed material onto the product, introduced into the plasma jet in the form of a powder. Spraying can be done with a mixture of two powders or a continuous spraying process can be carried out by moving from one dispenser to another.
When colliding with a product, particles that are in a molten or plastic state are deformed and embedded in the micro-irregularities of the product or plastically deform it with the formation of common points of physical and chemical interaction, ensuring adhesion strength and coating density. The formation of a coating layer of the required thickness is carried out by layer-by-layer spraying when moving the plasma torch relative to the sprayed surface.
The power supply to the plasma torch from the rectifier for plasma spraying “UPU-10” is controlled through the control cabinet. In the latter, in addition, there is a gas panel, to which gas from cylinders is supplied.
Cooling of plasmatrons with distilled water is carried out from an autonomous closed system, which is involved in the overall semi-automatic operating cycle of the plasma installation.

The applied powders are introduced into the plasmatron from a vibro-mechanical dispenser by a flow of transport gas through elastic tubes.
The technological capabilities of "UPU-10" have been expanded through the use of two dispensers, which allows you to change the nature of the powder, spray with a mixture of two powders, and carry out a continuous spraying process by switching from one dispenser to another. The quality of “UPU-10” deposition is improved by varying the amount of energy input into the plasmatron (by changing current and voltage). The service life of the cathode and anode of the plasma torch has been increased due to a smooth increase in current after excitation of the arc, the ability to operate at low (<315 A) currents, at increased (180 V) voltages and the use of bidistillate for cooling the plasma torch.

The “UPU-10” plant includes the following main components:
- Plasmatron;
- Dispenser;
- Water cooling system;
- Power supply;
- Gas and water distribution;
- Control cabinet.
