"UMP-500" plant is designed for deposition of protective coatings via gas circulation method.
This method of deposition is used to protect the surface of steel with chromium. Passing vaporous chromium chloride over the surface of steel heated to 1000°C ensures the formation of a chromium coating firmly adhered to the base through an intermediate layer of Fe-Cr alloy with a chromium content of up to 30%. The advantages of the method are the low porosity of the coatings and the possibility of metallization of internal surfaces and parts of complex configurations; the disadvantage is low productivity due to diffusion processes or chemical reactions at the interface.
With the vacuum method, chromed products are either in contact with chromium powder or at some distance from it. The vacuum facilitates the evaporation of chromium and its transfer to the surface being treated. The saturation of the surface with chromium occurs due to the formation of a vapor phase containing chromium at high temperature.
"UMP-500" is a modern equipment and is characterized by a compact design, equipped with a coating reactor.
