On the performance of a silicon nitride cutting tool in machining steel

Ceramic Cutting Tools

“…Crater formation on the tool is the predominant wear feature providing evidence of the increased contribution of chemical wear in steel machining (Kramer & Judd, 1985;Kannatey-Asibu, 1999). Diffusion couples have shown that the chemical reactivity of Si 3 N 4 is higher in contact with steel than with gray cast iron.…”

Fabrication and dry cutting performance of Si3N4/TiC ceramic tools reinforced with the PVD WS2/Zr soft-coatings

“…However, in dry cutting, there will be more friction and adhesion at the tool-chip interface and toolworkpiece interface, the adhesions are peeled-off from the ceramic tool surface and then the ceramic fragments or grains are pulled out and taken away, which causes a higher tool wear and results in a lower tool life [4,5].…”
