The Adhesive Capacity of Corundum Ceramics Regulated by Low-Pressure CCP Plasma

Abstract

A comprehensive study was conducted on the effect of plasma treatment under conditions of a high-frequency low-pressure discharge on the physical and mechanical characteristics of technical corundum ceramics. The main goal of the study was to modify the surface and strength properties of the material. It was experimentally determined that plasma treatment significantly improves the key parameters of the material. In particular, there was a significant decrease in the contact angle of water wetting from 83° to 21°, indicating an increase in the surface energy of the material.
