The invention provides a high-abrasion Ti(C, N) based
metal ceramic tool and a preparation thereof. The Ti(C, N) based
metal ceramic tool uses Ni and Co as a binder phase, is added with at least one carbonitride of Ti(Cx, N1-x) or (TiC)x plus (
TiN)1-x as a basic batch, and consists of at least one composition of WC, Mo2C, Co, Ni, ZrC, Cr3C2, VC, TaC and NbC, and the balance being Ti(Cx, N1-x) or (TiC)x plus (
TiN)1-x, wherein, an X value for adding the carbonitride of the Ti(C, N) based
metal ceramic tool is as follows: X is less than or equal to 0.5 and more than or equal to 0.4, or the X is more than 0.5 and less than or equal to 0.7. The Ti(C, N) based metal ceramic tool is prepared according to the content of
nitrogen by
nitrogen pressure
sintering or
vacuum sintering combined with
hot isostatic pressing treatment, thereby preventing
nitrogen from escaping during the process of
sintering high-nitrogen
alloy, so that the high-nitrogen-carbon ratio in matrix and
material hardness can be reliably guaranteed, and anti-oxidative abrasion property and anti-diffusive abrasion property of the material can be obviously increased through adding slight ZrC, Cr3C2, VC and other carbides into the basic batch; meanwhile, compactability and buckling strength of a low-nitrogen
alloy structure can be obviously improved through optimally distributing each composition and content. The Ti(C, N) based metal ceramic tool is widely suitable for high-speed
cutting tools of medium-low
carbon steel and low
alloy steel.
