Material green compact molding die and tabletting method.
Background technique
The concept of function-graded material (Functional Gradient Materials, FGM) is by Japanese scholars Xinye
Just it, horizontal well is quick male and crosses what Bian Longsan put forward first, refer to the compound of the material of two kinds of different performances, constituent material
Element (component, structure) along a direction in continuously change of gradient, to obtain a kind of property and function is also in the direction
Advanced composite material (ACM) (M. Koizumi. FGM activities in Japan [J] the Composites of change of gradient
Part B. 1997 (1)).
The concept of function-graded material is introduced into the research field of sintex by Zhao Jun, is put forward for the first time gradient function ceramics
Designing a model for cutter material, i.e., one-dimensional, two and three dimensions FUNCTIONALLY GRADED CERAMIC TOOL model ([1] Ai Xing, Zhao
Jun, etal. Development of an advanced ceramic tool materials-Functionally
gradient cutting ceramics. Materials Science and Engineering , A ,1998, 248
(1-2): 125 ~ 131), and Al is successfully developed2O3/(W,Ti)C+Al2O3The one-dimensional gradient function ceramics of two kinds of systems of/TiC
Cutter.
Due to preparing the limitation of difficulty, the research of FUNCTIONALLY GRADED CERAMIC TOOL model is mainly one-dimentional structure at present, and right
In two-dimensional structure research report it is less, the preparation of current two-dimensional structure cutter be developed in one-dimentional structure preparation method and
Come, after the compacting of one-dimensional cutter and sinter molding, by certain angle cutting into ([2] Ni Xiuying is based on fatigue crack
The two-dimensional gradient sintex development of extension and Study on Cutting Performance [D] Shandong University, 2018.), therefore, two-dimensional gradient ceramics
Cutter is in structure, relative to the variation of two-dimensional gradient sintex not substantially；The system of three-dimensional gradient function ceramics cutter
It is standby not to be seen in report also at present.
Chinese patent " 106083065 A of application publication number CN " reports a kind of high-performance Si3N4-TiC0.5N0.5Compound ladder
Degree ceramic cutting tool material and preparation method thereof and Chinese patent " 102320170 B of Authorization Notice No. CN " report a kind of ladder
Nano composite ceramic cutter material and preparation method thereof is spent, wherein the compacting for FUNCTIONALLY GRADED CERAMIC TOOL green compact only uses
Powder place Min layers fill out method, and do not do detailed operating instruction.Compacting for FUNCTIONALLY GRADED CERAMIC TOOL green compact, at present compared with
Universal method after powder is filled out paving uniformly, is horizontally suppressed in layer using cylindrical pressuring rod using cylindrical mold cavity
Powder, then subsequent sintering preparation process is carried out, to form one-dimensional FUNCTIONALLY GRADED CERAMIC TOOL.Two-dimensional gradient function ceramics knife
Tool still falls within the scope of one-dimensional FUNCTIONALLY GRADED CERAMIC TOOL from the point of view of current preparation method.Therefore it needs a kind of can directly press
The mold of two-dimensional gradient function ceramics cutter material processed, Chinese patent " 107379619 A of application publication number CN " report one kind
It is easy to move back the powder presser die and tabletting method of mould, compression mold and tabletting method can be used for making molding one-dimensional ladder
Function ceramics cutter green compact are spent, but still can not two-dimensional gradient function ceramics cutter molding green compact.
