Description

A kind of WC-TaC-CsfObdurability material and preparation method thereof
Technical field
The present invention relates to high-speed cutting obdurability sintex field, specially a kind of WC-TaC-Csf obdurabilities material And preparation method thereof.
Background technology
The method of multiple elements design can improve WC（Tungsten carbide）The sintering character of base ceramic material reduces its sintering temperature, Make it that can reach densification, and appropriate material component, grain growth inhibitor and sintering process at a lower temperature It can make crystal grain refinement, and then improve the mechanical property of material.
In many series hard alloys, tungsten-cobalt series hard alloy (WC-Co) is most widely used.But metal Co（Cobalt）Very It is rare and be non-renewable strategic resources, metal N（Nickel）Due to having good wettability, and nothing to WC as Co Poison, cheap and WC-Ni hard alloy have fairly good inoxidizability and corrosion resistance, and some researches show that with Ni generations Co is feasible as hardmetall binder.
But sintex its intrinsic brittleness limits its application to a certain extent, how to improve its toughness and intensity It is a hot and difficult issue of current ceramic material area research.
The preparation method of existing WC base ceramic materials has：XD method, SHS technology are burnt without pressure Knot and explosive sintering etc..Conventional preparation techniques are complicated, of high cost, the deficiencies of being unfavorable for industrialization part.
Invention content
The present invention provides one kind to solve the problems, such as that existing sintex is strong there are brittleness and toughness and intensity are relatively low WC-TaC-Csf obdurability materials and preparation method thereof.
The present invention adopts the following technical scheme that realization：A kind of WC-TaC-Csf obdurabilities material is by following quality The raw material composition of number：1-4 parts of 82-92.5 parts of WC, TaC, Csf0.5-2 parts, 6-12 parts of Ni.
WC-TaC-CsfThe selection of each component and content in obdurability material is obtained by experiment largely repeatedly, tool There are purity height, chopped carbon fiber CsfThe advantages of being evenly distributed, the size of WC grain is between 2 μm -5 μm, WC-TaC-CsfMaterial Fracture toughness overcomes that existing sintex is strong there are brittleness and toughness and intensity are relatively low between 15MPam ~ 20MPam The problem of.
A kind of preparation method of WC-TaC-Csf obdurabilities material, using following steps：A, by WC, TaC, Csf, Ni mixing Powder is fitted into horizontal tank abrading-ball grinding machine, with being sieved after hard alloy ball milling；B, the dispensing after sieving is packed into what is closed up and down Crystal vessel is placed into high temperature sintering furnace；C, 10 DEG C/min of heating rate, pressure 30MPa, 1450 DEG C of sintering temperature- WC-TaC-Csf obdurability materials are made after 30min-75min is kept the temperature under conditions of 1600 DEG C.
Using vacuum heating-press sintering method, there is technique to simplify, it is at low cost and the advantages of conducive to industrial operations.
The present invention has the advantages that：Maintain the same of the preferable mechanical performance of sintex and high temperature resistance When, the brittleness of sintex is overcome, effectively increases its toughness and intensity, has simple for process, at low cost and is conducive to produce The advantages of industry, is suitable for high-speed cutting processing field.
