Amount is 35-60wt.%, and TiC content is 35-60wt.%, and VN content is 5-10wt.%;The group of third layer is divided into:Al2O3Content
For 40-60wt.%, TiC content is 40-60wt.%;Micro- texture is machined in cutter rake face.
2. a kind of Al2O3The preparation process of the adaptive texture gradient sintex of/TiC/VN, it is characterised in that:Preparation process includes
Ingredient, charging and sintering, the micro- texture of laser processing, specific step of preparation process are as follows:
(1) ingredient:Al2O3Powder size is 0.5-1.0 μm, and TiC powder granularity is 0.5-1.0 μm, and VN powder size is 0.5-
1.0 μm, by Al2O3, tri- kinds of powder of TiC, VN configure mixed-powder by a certain percentage, the ratio of mixed-powder is as follows:First layer and
The group of layer 5 is divided into:Al2O3Content is 30-65wt.%, and TiC content is 30-65wt.%, and VN content is 10-30wt.%;The
Two layers and the 4th layer of group is divided into:Al2O3Content is 35-60wt.%, and TiC content is 35-60wt.%, and VN content is 5-
10wt.%;The group of third layer is divided into:Al2O3Content is 40-60wt.%, and TiC content is 40-60wt.%;It will be configured mixed
Conjunction powder is respectively charged into ball mill progress ball milling and uses Al using dehydrated alcohol as medium2O3Ceramic Balls ball milling 48h, vacuum are dry
It is spare with 100 mesh sieves after dry;
(2) it charges and is sintered:The mixed-powder prepared is fitted into high strength graphite mold in such a way that place Min layers are filled out, point
The sequence that layer paving is filled out is layer 5, the 4th layer, third layer, the second layer, first layer, gradually rises the content of VN from inside to outside,
Carry out hot pressed sintering under vacuum conditions, sintering range is 1700-1800 DEG C, sintering pressure 30-40MPa, when heat preservation
Between be 30-60min;
(3) micro- texture is laser machined:The micro- of groove pattern is processed in the sintex rake face sintered using nanosecond laser
Texture, texture groove are oriented parallel to main cutting edge, and texture width is 30-50 μm, and texture depth is 30-50 μm, texture spacing
It is 50-400 μm, distance of the texture edge far from main cutting edge is 40-100 μm.
