Device for gas-thermal oxidation of products from titanium and titanium-containing alloys

摘要

The utility model relates to equipment for the thermal treatment (oxidation) of titanium products and titanium-containing alloys used in instrumentation, shipbuilding, rocket science, mechanical engineering, implant medicine in order to increase the strength characteristics and protective properties of the surface. The technical result of the utility model is to give the surface of titanium products and titanium-containing alloys a wide range of functional properties and operational characteristics due to the production of thermo-oxide coatings modified by particles of various powder materials, as well as to ensure high uniformity of powder supply into the oxidation chamber of the device while reducing its consumption. A device for gas-thermal oxidation of titanium and titanium-containing alloy products, comprising an oxidation chamber with a heating system, a gas mixture supply unit to the oxidation chamber, and a node for removing the gas mixture from the gas mixture chamber, the oxidation chamber is provided with a cooling system, the device further comprises a cooling chamber for oxidized products, having nodes for flowing into it a cooling inert gas medium and its outlet and connected to the oxidation chamber by means of a lock gate in the form of two x hemispherical locking elements, made with the ability to open and close the through hole in the lock gate to connect or separate the volumes of both chambers, the cooling system of the oxidation chamber is made in the form of circulation loops with a cooling liquid medium, located at an equal distance from the heating system in the form of a heating element, placed on the body of the oxidation chamber and closed on the outside by a casing, in addition, the device has two covers that cover the device with two On the other hand, one cover is installed on the side of the oxidation chamber in which the assembly for supplying the gas mixture is mounted, and the second cover is mounted on the side of the cooling chamber and is provided with a latch, the assembly for supplying the gas mixture further comprises a system for the metered supply of powder materials and oxidizing gas medium, equipped with a vibrator to prevent coagulation of particles of powder materials and ensure their uniform supply. 1 s.p. f-ly, 1 ill.
