Processing the Inner Surfaces of Hollow Ceramic Samples with the Use of Fast Argon Atom Beams

To increase the wear resistance of a hollow ceramic product, it is necessary to apply wear-resistant coatings to all its surfaces, including the internal surfaces. Before the coating deposition, the surface must be processed with a beam of energetic particles to ensure its adhesion. In this study, a scheme for processing internal surfaces of hollow cylinders with fast argon atoms is proposed and tested. Simultaneous treatment of all surfaces of the rotating ceramic cylinder allowed for deposition of a uniform TiB2 coating on both sides of the cylinder and a decrease in the abrasion wear by several times.
