RUSNANO project company "Plakart" has launched a new line of plasma surfacing in Scherbinka Moscow region.
This line combined with the already running in production equipment and high-speed gas thermal spraying will allow the company to offer almost all currently known solutions for the protection of steel against corrosion and wear. The total project budget is around 4 billion, including co-financing in the amount of RUSNANO 1,220 million.
"The plant in Sherbinka is one of the best equipped production facilities on application of nano in Russia, — says RUSNANO Managing Director Alexander Kondrashov. — This is not the only production site "Plakarta" — already successfully operating branches in Perm and Tyumen. In the near future plans to open sites in St. Petersburg, Nizhny Novgorod, Almetyevsk. We are confident that through a wide network of branches, modern equipment and its own know-how of the company "Plakart" will occupy an increasingly important position in the Russian market, the application of nano ".
"We are constantly working on the development and introduction of new surface technology — thermal spraying and welding — said General Director of" Plakart "Vitaly Geras'kin. — Introduction of a plasma deposition will significantly expand the range of our proposed wear-resistant coatings, and installation trehanodnaya plasma spraying — the next step in improving the productivity and quality of the application of ceramic coatings ".
Launched line consists of two complexes
1. Automated complex plasma deposition, which allows to obtain the desired structure of deposited nanolayer at the first application that allows you to extend the life of products from 3 to 10 times.
2. Trehanodnaya plasma spraying installation, which can be used for a wide range of nano-coating on various surfaces — from metals and alloys to refractory ceramics.
Automated complex plasma deposition, which allows to obtain the desired structure of deposited nanolayer at the first application that allows you to extend the life of products from 3 to 10 times. In addition, compared with other methods of applying the nano substantially increased deposition efficiency of the process and the use of the powder, on the contrary, reduced. The technology of plasma-powder surfacing can be used to improve the reliability and service life of a wide range of products — for example, valves for the energy, marine, petrochemical and general engineering.
Trehanodnaya plasma spraying installation Delta, which can be used for a wide range of nano-coating on various surfaces — from metals and alloys to refractory ceramics. The complex is used, primarily, for the deposition of ceramic coatings on turbine components (combustor blade parts hot section) in the printing industry (ceramic shaft) and metal (shaft line galvanizing furnace rollers).
Plasma spraying technology may be used for coating a wide range — from metals and alloys to refractory ceramics. These particles are introduced in powder form into the plasma stream whose temperature at the exit of the plasma torch is of the order of 15,000 K, the flow rate of the order of about 300 m / s. The plasma stream is produced by plasma torches or plasma torches, the bulk of which is cone-shaped tungsten cathode and copper hollow cylindrical anode, followed by a nozzle. The gas supplied between the cathode and the anode, an electric arc heats a moving forming the hot stream.
Thermal spraying is one of the fastest growing methods of applying coatings. The method relies on obtaining high-speed gas stream produced by passing the gases through the heat source. Solid particles, typically in powder form, are introduced into the gas stream is partially or completely melted on the substrate and form a lamellar structure. The heat source can be used as the combustion energy of the liquid fuel with the oxygen (e.g., the method HVOF — high speed flame spraying), and the energy of the arc (e.g., the method of APS — atmospheric plasma spraying). Particles in the gas streams produced by the above methods have different temperatures and velocities that cause their application in various industries.
