Preparation of Al(2)O(3)/Ti(C,N)/ZrO(2)/CaF(2)@Al(OH)(3) Ceramic Tools and Cutting Performance in Turning
Aiming at the contradiction between the lubricating performance and mechanical performance of self-lubricating ceramic tools. CaF(2)@Al(OH)(3) particles were prepared by the heterogeneous nucleation method. An Al(2)O(3)/Ti(C,N) ceramic tool with CaF(2)@Al(2)(OH)(3) particles and ZrO(2) whiskers was...

description | Aiming at the contradiction between the lubricating performance and mechanical performance of self-lubricating ceramic tools. CaF(2)@Al(OH)(3) particles were prepared by the heterogeneous nucleation method. An Al(2)O(3)/Ti(C,N) ceramic tool with CaF(2)@Al(2)(OH)(3) particles and ZrO(2) whiskers was prepared by hot press sintering (frittage). The cutting performances and wear mechanisms of this ceramic tool were investigated. Compared with the Al(2)O(3)/Ti(C,N) ceramic tool, the Al(2)O(3)/Ti(C,N)/ZrO(2)/CaF(2)@Al(OH)(3) ceramic tool had lower cutting temperatures and surface roughness. When the cutting speed was increased from 100 m/min to 300 m/min, a lot of CaF(2) was smeared onto the surface of the ceramic tool, and the flank wear of the Al(2)O(3)/Ti(C,N)/ZrO(2)/CaF(2)@Al(OH)(3) ceramic tool was reduced. The main wear mechanisms of the Al(2)O(3)/Ti(C,N)/ZrO(2)/CaF(2)@Al(OH)(3) ceramic tool were adhesive wear and micro-chipping. The formation of solid lubricating film and the improvement of fracture toughness by adding ZrO(2) whiskers and CaF(2)@Al(OH)(3) were important factors for the Al(2)O(3)/Ti(C,N)/ZrO(2)/CaF(2)@Al(OH)(3) ceramic tool to have better cutting performances. |
