Self healing ability and strength recovery of different laminated Al2O3 cutting tool composites [PDF]

open access: yes, 2020
The lifetime of ceramic tool is decreased because of the extension of cracks, and it will be prolonged if the cracks can be self healed. The healing ability of laminated Al2O3 cutting tool composites (Al2O3-(WC-Co)-MgO/Al2O3–TiC–MgO) were assessed.

Characterisation and Performance Optimisation of WC-MC/M(C,N)-Co Hardmetals

open access: yesMetals, 2019
WC-MC/M(C,N)-Co hardmetals with 10 wt% Co were prepared in undoped, as well as in either Cr- or V-doped form. The starting formulations contained 5 wt% TiC or 5% (TiC+TiN), the latter with two different TiC/TiN ratios, and 10 wt% (Ta,Nb)C.
