Sharpening of ceramic knife-edges and production of plasma for cutting tools nitriding with the use of a broad fast molecule beam

Abstract

-A source of gas molecules with energy ranging from 0.5 up to 4 keV has been used for production of non-self-sustained glow discharge plasma. Cutting tools immersed in nitrogen plasma are heated by the fast molecules but they are not sputtered by ions from the plasma. During nitriding of a tool the fast molecules sputter its cutting edges with the same rate as the rest of the tool surface. It results in a decrease of the edge radius. For sharpening of ceramic knife-edges were used fast neutral argon atoms, which sputter materials more intensively than nitrogen molecules.

“…Dear Editorial board, It has come to my attention that the paper authored by Prof. Dr. A.S. Metel and published in the Journal Mechanics & Industry in December 2016 [1] contains large portions of the text from another his article [2], published in 2011. In fact, the article [1] was aimed to extend the absolutely new and never published results obtained in the article [2].…”

“…In fact, the article [1] was aimed to extend the absolutely new and never published results obtained in the article [2]. In the article [2], the authors study parameters of nitrogen plasma and discuss absolutely new results related to the plasma production by fast neutral molecule beam.…”
