Poor, the common bending strength of TiC, TiN and Ti (C, N) based ceramic metal is between 1000~2000MPa, and common WC-
The bending strength of Co series hard alloy is developed between 1800~3500MPa, but due to W and Co shortage of resources without tungsten metal
Ceramics seem very urgent.
TiC, TiN and Ti (C, N) based ceramic metal primary raw material is resourceful, at low cost, but its obdurability and WC-Co
There is also biggish gaps for series hard alloy obdurability, at present only in chip cutter field as WC-Co series hard alloy
Alternative materials, in WC-Co series hard alloy others field, such as drilling field realizes good utilization not yet, thus how to mention
The obdurability of high TiC, TiN and Ti (C, N) based ceramic metal is the hot spot of a research.
