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
It with Ti (C, N) is main hard phase that Ti (C, N) based ceramic metal, which is a kind of, Ni is Binder Phase, 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 friction coefficient 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, cost of manufacture is only the 35~55% of hard alloy,
Therefore the concern of investigation of materials personnel is received.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
Brittle failure easily occurs under border and fails, the deficiency of obdurability makes its application field be greatly limited, this, which also becomes to restrict, is somebody's turn to do
Material replaces the main factor of WC-Co hard alloy.
Traditional Ti (C, N) based ceramic metal is generally by adding Mo2C (or Mo), WC etc. improve the comprehensive of cermet
Close mechanical property.The addition of these additives is so that the microscopic structure of cermet shows 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 ingredient transitivity parameter so that material is easy crack initiation and is occurred when by external load function, on interface
Proliferation and extension.This is one of the main reason for obdurability of Ti (C, N) based ceramic metal is less than hard alloy.
Whisker or fiber are added into ceramic matrix, utilize the higher intensity of filler and elasticity modulus and non-geometric elasticity
The features such as bodily form looks, to improve the obdurability of ceramic material, 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 reach 1900MPa, and fracture toughness reaches 9.5MPam1/2Although improving the tough of material to a certain extent
Property, but the application effect compared to whisker in ceramic material, promotion amplitude still are apparent not enough.Microstructure observation shows SiC
Whisker fails to effectively be uniformly distributed in metal-ceramic matrix, and this is mainly due to SiC whiskers to be directly added to mix
Ball milling dispersion is carried out in powder, since material system is complex, mechanical milling process extremely be easy to cause segregation and the destruction of whisker,
So that whisker cannot achieve 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 environmental-friendly high-strength filler, ensure that it, can in ceramic matrix under conditions of uniform distribution
It is the new approaches for researching and developing novel high-strength base titanium carbonitride to stablize the 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 of the various biomechanical property structures of nature.It is compared with numerous inorganic nano-particles, it is fine
Dimension element is nanocrystalline to be had its unique advantages, the hypotoxicity, high crystalline and the Rod-like shape that such as have been demonstrated, high-specific surface area and
Rigidity modulus, biodegradable, biocompatible etc..Especially it is worth noting that, pass through amorphous regions in removing cellulose
Obtained highly crystalline Cellulose nanocrystal, elasticity modulus reach 100-150GPa, specific modulus and aramid fiber (Kevlar) phase
When, or even it is 3-4 times higher than glass fibre (reinforcing filler for being widely used as composite material) and steel.Cellulose nanocrystal is with its height
Mechanical moduli and stick characteristics are widely used in the reinforcing filler of various compound systems.
