Description
Technical field
The invention belongs to ceramic matric composite and powder metallurgical technology, it is related to a kind of high-strength tenacity cermet
Preparation method, and in particular to a kind of Strengthening and Toughening base titanium carbonitride and preparation method.
Background technology
Ti (C, N) based ceramic metal be it is a kind of be that main hard phase, Ni are Binder Phase with Ti (C, N), using powder metallurgy
Ceramic matric composite prepared by technique.Compared with WC-Co hard alloy, cermet has more preferably red hardness, wearability
And inoxidizability, and its coefficient of friction between metal is relatively low, is the reason for making high-speed and high-efficiency cutting tool and hot forming tool
Think material.In addition, the reserves of cermet main component more horn of plenty, its cost of manufacture is only the 35~55% of hard alloy,
Therefore the concern of investigation of materials personnel is enjoyed.However, with hard alloy high tenacity (fracture toughness about 9~16MPam1/2) phase
It is still more relatively low than the toughness of, Ti (C, N) based ceramic metal that (fracture toughness is about 6~9MPam1/2), shaking larger military service ring
Easily occur brittle failure under border and fail, the deficiency of obdurability is greatly limited its application field, this also turns into restriction should
Material replaces the main factor of WC-Co hard alloy.
Traditional Ti (C, N) based ceramic metal is typically by adding Mo2C (or Mo), WC etc. improve the comprehensive of cermet
Close mechanical property.The addition of these additives causes the microscopic structure of cermet to show typical core-ring structure, although ring
Shape mutually improves the wetability between ceramic crystalline grain and metallic binding phase, but a large amount of boundaries present in core ring structured,
And the difference in composition transitivity parameter so that material easy crack initiation and occurs when by external load function, on interface
Propagation and extension.This is that the obdurability of Ti (C, N) based ceramic metal is less than the one of the main reasons of hard alloy.
Whisker or fiber are added into ceramic matrix, the higher intensity of filler and modulus of elasticity and non-geometric elasticity is utilized
The features such as bodily form looks, so that the obdurability of ceramic material is improved, by ceramic matric composite researcher's wide coverage.If any grinding
The addition SiC whiskers in mechanical milling process are studied carefully, then by obtaining Ti (C, N) based ceramic metal after the techniques such as molding, vacuum-sintering
Material, intensity reaches 1900MPa, and fracture toughness reaches 9.5MPam1/2, although the tough of material is improved to a certain extent
Property, but the application effect compared to whisker in ceramic material, its lifting amplitude still are apparent not enough.Microstructure observation shows SiC
Whisker fails to effectively be uniformly distributed in metal-ceramic matrix, and this is directly added to mixing mainly due to SiC whiskers
Carry out ball milling in powder to disperse, because material system is complex, mechanical milling process extremely easily causes segregation and the destruction of whisker,
Hence in so that whisker can not realize useful effect.On the other hand, the use of inorganic filler will necessarily be to environmental and human health impacts band
To influence.Therefore, using a kind of environment-friendly high-strength filler, it is ensured that it, can in ceramic matrix under conditions of homogeneous distribution
It is the new approaches for researching and developing novel high-strength base titanium carbonitride with the stable mechanical property for improving composite ceramics.
The Cellulose nanocrystal extracted from native cellulose resource, is that a kind of rigid rod biomass of highly crystalline is received
Rice corpuscles, it is considered to be the infrastructure elements that the various biomechanical properties of nature are built.Compared with numerous inorganic nano-particles, it is fine
Dimension element it is nanocrystalline have its unique advantage, the hypotoxicity such as having been demonstrated, high crystalline and Rod-like shape, high-specific surface area and
Rigidity modulus, biodegradable, biocompatible etc..Especially it is worthy of note that, by removing amorphous regions in cellulose
Obtained highly crystalline Cellulose nanocrystal, its modulus of elasticity reaches 100-150GPa, specific modulus and aramid fiber (Kevlar) phase
When, or even it is higher 3-4 times than glass fibre (reinforcer for being widely used as composite) and steel.Cellulose nanocrystal is high with it
Mechanical moduli and stick characteristics, are widely used in the reinforcer of various compound systems.
