Abstract
Hard alloy base material used for coating tool Bits of the present invention contains TiC, TaC, NbC, WC, Co and denier Cr
3C
2Its intensity reaches 190kg/mm
2More than, hardness reaches HRA91.The work-ing life of the coated cutting tool made from it, more coated cutting tool did not improve 1～5 times, and cutting speed improves 0.5～1 times.In addition, also can be used as the bigger cutter material that withstands shocks, as rotary file etc.
Description
The technical field of the invention: mmaterial.
Description of contents of the present invention:
For wear resistance and the anti-tipping blade ability that improves carbide chip, so that obtain long service life, the metal cutting tool that working (machining) efficiency is high, people are depositing TiC, TiN, Al with vapour deposition process on the carbide chip surface
2O
3, Ti(CN) etc. single coating or overbrushing layer, the wear resistance of blade and anti-tipping blade ability are increased substantially, improve 1～5 times cutter life thereby can make.With public known YT14 Hardmetal materials or YT 5 carbide material matrix as coated chip, obtain the coating of 2-8 micron thickness through vapour deposition after, though wear resistance is better, but the transition key coat between coating and hard alloy substrate descends 15～25% because of poor carbon makes this matrix strength, and cutter anti-tipping blade ability is descended significantly.Can not bring into play the wear resistance and the anti-tipping blade ability of coating like this, give on the contrary and use cutter producer to bring very large economy loss.At above-mentioned shortcoming, developed and a kind ofly can overcome above-mentioned shortcoming, have sufficient intensity, wear resistance and the good hard alloy base material used for coating tool Bits of anti-tipping blade ability again.
Technical essential of the present invention is: be 5.85～6.00% tungsten-carbide powder (WC powder) with total carbon; The Fu Shi mean particle size value of powder is 1.8～3.5 microns.Add that tantalum carbide powder (TaC powder), niobium carbide powder (NbC powder), titanium carbide powder (TiC powder), titanium dioxide powder (TiO2 powder) and carbon black (C) make composite carbide sosoloid.Then, add tungsten carbide powder and the Cobalt powder is made compound.Through compression moulding and vacuum sintering, and make weight percent be: TiC-1.2～10.0%, TaC-2.0～5.0%, NbC-1.0～5.0%, Co-5.0～10.0%, Cr
3C
2-0.25～0.45%, all the other are the hard alloy base material used for coating tool Bits that WC and inevitable trace impurity are formed.
Hard alloy base material used for coating tool Bits of the present invention adopts following method to make:
1. make the main technologic parameters of composite carbide sosoloid
1. stove ratio of components:
Composite carbide sosoloid is pressed column weight amount per-cent preparation (scope)
TiO
2-30～35%
Carbon black-12～18%
TiC-3～8%
TaC-5～15%
NbC-6～12%
WC-all the other
2. pressure is rolled into a ball:
Furnace charge by above-mentioned per-cent preparation mixes through cylinder, in the mould of packing into then, with 200 kilograms per centimeter
2Pressure, suppress agglomerating.
3. composite carbide sosoloid is synthetic:
The furnace charge that compacting is agglomerating, placing vacuum tightness is 2～3 * 10
-1Mmhg vacuum oven internal heating to 1750～1800 ℃ is incubated 2 hours, and cooling is subsequently made.
4. broken sosoloid, and sieve with 120 mesh sieve.
2. compound preparation
Compound is made up of solid solution powder, tungsten carbide powder and Cobalt powder, according to the composition ratio preparation compound of determining.Ball milling standard in accordance with regulations with the compound ball milling after, place 60～80 ℃ of vacuum drying oven inner dryings.Thereafter with the sodium butadiene rubber gasoline solution of 4% concentration, the ratio in compound equals 5 to 1 than sodium butadiene rubber gasoline solution adds in the compound, carries out strike-through.Behind the compound strike-through, sieve, be pressed into the blade of desired shape through stirring.
3. vacuum sintering
It is 2.2 * 10 that the blade of compression moulding is placed vacuum tightness
-1～1 * 10
-1Mmhg vacuum oven internal heating to 1460～1480 ℃ insulation 45～60 minutes is then at the stove internal cooling.
The bending strength of hard alloy base material used for coating tool Bits of the present invention reaches 190 kilograms/millimeter
2More than, hardness reaches more than the HRA91, and porosity is less than 0.2%, and the metallographic structure of alloy is that twin crystal grain wolfram varbide and composite carbide sosoloid are formed.After deposition goes up individual layer or composite laminated coating, make cutter have good wear resistance and anti-tipping blade ability thereon.
