Plasma-Beam Processing of Tools Made of SiAlON Dielectric Ceramics to Increase Wear Resistance When Cutting Nickel–Chromium Alloys

This research aimed at an increase in wear resistance of round cutting plates manufactured with SiAlON dielectric ceramics through deposition wear-resistant coatings. To effectiveness the coatings, their adhesion was improved by removal defective surface layers from before deposition. As depth caverns and grooves appearing on due to manufacturing diamond grinding reached 5 µm, a concentrated beam fast argon atoms used for thickness exceeding grooves. At equal angles incidence front back surfaces wedge amounting 45 degrees, two-hour-long etching rotating provided ~10 µm surfaces. After removal, edge radius diminished 20 10 which indicates plates’ sharpening. Wear-resistant TiAlN coatings deposited after significantly improve processing stability not less than 1.7 times.
