PROFESSIONAL ADVICE

For preliminary ionic surface treatment and ion assistance, the following have been
developed: inverse-type MRS (InvMRS), a gas ion accelerator with a closed electron drift. The
technology for processing parts of various types provided for the use of integrated technological
devices, including developed individual plasma technological devices in various combinations.
The possibility of providing application technologies was considered. coatings of various
compositions and purposes, including multilayer, composite and nanostructured ones. Rare-
earth permanent magnets of the N 38 type were used in the construction of plasma devices.
The design of technological devices was tested using model cathodes made of steel 12X18N10T.
To solve the urgent problem of replacing galvanic chromium plating with ion-plasma deposition
technology, cast chromium cathodes and tubular composite cathodes were used.
