Combined vacuum plasma surface treatment for increase of durability of face milling cutters from high‐speed steel

Abstract

The article deals with the influence of the vacuum plasma surface treatment on the life of the face milling cutter of high-speed steel R6M5 (analog M2 (USA, AISI/ ASTM)). Such processing combines ion nitriding in gas plasma and the deposition of the wear-resistant TiAlN layer in the metal gas plasma of the vacuum-arc discharge. Research verifies that the use of vacuum plasma treatment combining the formation of the transition nitrided layer in the gas plasma and the subsequent deposition of TiAlN coating in metal gas plasma created by a vacuum-arc discharge is an effective way to improve the tool life of high-speed steel face milling cutters.

The Features of Nanocomposite Structure Formation on the Surface of Metal Products under the Influence of Low-Temperature Plasma

“…The current stage of development of production in various sectors is characterized by tighter operating conditions of products from metal materials and alloys associated with the effect of high temperatures, the external power loads and corrosive environments. This requires continuous improvement of existing and development of new manufacturing technologies including technology of strengthening their surface layer [1,2], in particular, plasma technologies: thermal hardening [3][4][5], plasma ion diffusion [6,7], ion-beam hardening treatment [8][9][10][11].…”
