Ion-plasma technology and equipment for applying thermostable nanostructured coatings
The technology and installation are intended for ion-plasma deposition of thermostable nanostructured coatings on machine parts and mechanisms, cutting tools, stamping equipment made of high-strength structural and tool steels and hard alloys with the aim of manifold increasing wear resistance, erosion, oxidation and corrosion resistance, thermal cyclic resistance, reducing the coefficient friction.
Brief description
The technology is based on the creation of nanocomposites or nanolaminates based on nitrides, carbides, borides or oxides of transition metals in the surface layer of parts. The technology makes it possible to obtain coatings that are self-strengthening when heated. The installation is equipped with two magnetron metal sputterers, an ion source for preliminary surface treatment of substrates with an ion flow and accompanying the deposition process by ion bombardment, as well as an independent resistive substrate heater. The design of the installation provides for the use of composite targets and cathodes, pulsed power supplies for magnetrons, and the supply of a bias potential to the substrates.
