Employees of the Department of Physical and Colloid Chemistry of the Faculty of Chemistry of Tomsk State University have developed a durable ceramic coating that makes an object invisible in the infrared spectrum of a thermal imager, cools it and protects it from electromagnetic influence. The development can find application in astronautics, electronics and other fields. Only domestic components are used in the formation of such coatings. The press service of TSU reported this to RT.

As the authors of the study explained, with the help of various coatings, new properties can be imparted to equipment and materials. For example, increase strength, reduce friction, provide protection from chemical and physical influences, etc. Coatings, the application of which makes an object invisible in infrared radiation, as well as protecting against electromagnetic interference, already exist. However, the problem is in the formation of sufficiently durable coatings that would not be destroyed by external influences.

The authors of the work managed to find a solution through a special coating technology and the formation of special functional structures that are included in the coating. The object that needs to be coated with a protective layer is placed in the solution, a current is supplied, which, due to electrode and plasma reactions, converts the components of the solution into a functional coating consisting of metal and metal oxides. A monolithic durable layer is formed. As chemists note, the technology makes it possible to create a coating even on the surface of objects with complex shapes. The application method has already been tested in industrial production.

Scientists have developed a composition for a new coating that can be applied using this method and tested it in laboratory tests. The next stage is the transition to testing in real conditions and application on an industrial scale. In addition to providing infrared invisibility, the coating allows you to protect equipment from electromagnetic interference, which is especially important when creating space technology.

The coating differs from analogues in its high strength and resistance to extreme temperatures. It has another potential application - cooling equipment in space, where there is no air and convection. Cooling occurs due to the high intensity of radiant heat exchange (thermal radiation.

“We have developed a specialized coating that gives new properties to devices and objects and protects the object from several factors at once,” said the project leader, Doctor of Chemical Sciences, Professor Doctor of Chemical Sciences. HF TSU Anatoly Mamaev.
