Abstract
This case discloses a kind of refractory metal ceramic die material, it is carried out melted and cast by the material of following weight/mass percentage composition and makes: the aluminium sesquioxide of the titanium carbide of the zirconium dioxide of the molybdenum of the cobalt of chromium, 3%～5%, 1%～3%, 5%～10%, 2%～8%, 5%～15% of 4%～12%, surplus is tungsten.The refractory metal ceramic die material that this case prepares not only has red hardness, heat stability, wearability, antioxidation and the high-temperature stability of excellence, and add zirconium/carbon dioxide titanium/this ceramic phase oxide-metal combinations of aluminium sesquioxide/silicon nitride, drastically increase the toughness of mould, mechanical strength, thermal shock resistance and anti-rapid heat cycle performance, significantly increasing the mold use life-span, the highest service life is more than 20,000 times.
Description
Technical field
The present invention relates to engineering material manufacture field, particularly to a kind of refractory metal ceramic die material.
Background technology
Mould is the technological equipment that each department of national economy is important, enjoys the good reputation of " mother of industry ".Mould
Tool molding has efficiency height, quality is good, save material, reduce many advantages such as cost.According to statistics,
The part of more than the 60% of the products such as aircraft, tank, automobile, tractor, electrical equipment and electrical, instrument and meter,
The part of more than the 85% of the products such as bicycle, washing machine, electric refrigerator, electric fan, air-conditioning, photographing unit,
Will produce with mould.Not having the industrial development that mould does not the most modernize, countries in the world are all paid much attention to
Mould industry.
Affect die life because have: design structure, shaping and manufacturing process, mold materials
Selection, Technology for Heating Processing and surface peening, lubrication and working service etc..Factors at mould invalidation
In, and the inefficacy that cause improper due to mould material, account for 50%.As can be seen here, correct with material pair
Play vital effect die life.
Traditional mold materials mostly is metal alloys material, but in recent years, continuous along with processing industry sends out
Exhibition is grown, and the quality of mould be it is also proposed the highest requirement.Maximize to pursue enterprise profit,
People continuously attempt to producing a kind of high life resistant to elevated temperatures high-quality mould, with overhead cost as far as possible
Put into.But traditional alloy mold universal life-span under high-temperature work environment is the highest, through high temperature and grinds for a long time
Damage easy to crack under damage.
Summary of the invention
In place of the deficiencies in the prior art, the present invention provides a kind of refractory metal ceramic die
Material, this material feedstock is easy to get, cheap for manufacturing cost, and preparation technology is simple.
Technical scheme is summarized as follows:
A kind of refractory metal ceramic die material, by the material of following weight/mass percentage composition carry out melted and
Cast is made:
Preferably, described refractory metal ceramic die material, by the material of following weight/mass percentage composition
Material carries out melted and cast and makes:
Preferably, described refractory metal ceramic die material, by the material of following weight/mass percentage composition
Material carries out melted and cast and makes:
Preferably, described refractory metal ceramic die material, described melted temperature range is
1630～1750 DEG C.
Preferably, described refractory metal ceramic die material, the temperature range of described cast is
1310～1390 DEG C.
The invention has the beneficial effects as follows: the cermet mold material that this case prepares not only has the red of excellence
Rigid, heat stability, wearability, antioxidation and high-temperature stability, and add zirconium/carbon dioxide titanium
This ceramic phase oxide-metal combinations of/aluminium sesquioxide/silicon nitride, drastically increase mould toughness,
Mechanical strength, thermal shock resistance and anti-rapid heat cycle performance, significantly increase the mold use life-span, the highest
Service life is more than 20,000 times.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, to make those skilled in the art join
Book word can be implemented according to this as directed.
This case proposes a kind of refractory metal ceramic die material, the material of following weight/mass percentage composition enter
Row is melted and cast is made:
Wherein, zirconium/carbon dioxide titanium/aluminium sesquioxide/silicon nitride is ceramic metal phase material, and it has concurrently
Metal and the advantage of pottery, they density are little, and hardness is high, and high temperature resistant, heat conductivity is good, will not be because of quenching
Shock heating and embrittlement.Aluminium sesquioxide and zirconium dioxide have high temperature resistant, chemical resistance of concrete, high mechanical properties
With advantage, titanium carbide and the silicon nitride such as high-termal conductivity, there is high temperature resistant, superhard, thermal shock resistance and good
The feature such as high temperature creep.
Add chromium, cobalt and molybdenum in the material, more excellent in order to play after melting with cermet material
Physical property, makes to be in during material solidification phase transformation eutectic point, it is simple to control moulding process, reduces mould and adds
Work cost.Manganese can regulate the critical quenching rate of material, increases the stability of material self.Tungsten conduct
The main body of material, can promote mechanical strength and high temperature resistant property, can also improve material simultaneously
Toughness, hardness, wearability and anti-rapid heat cycle ability.
In the preparation, after being mixed by each raw material by above-mentioned formula, carry out respectively melting and pouring into a mould, melted
Temperature range is preferably 1630～1750 DEG C, too low, causes raw material fully to merge；For ensureing to melt
The mobility of rear raw material, when cast, its temperature range is preferably 1310～1390 DEG C.After being cast
Annealing process then uses the conventional process of this area.Mold materials hot strength ＞ prepared
4500Mpa, impact flexibility ＞ 70J/cm2, HRC ＞ 70, high temperature life ＞ 20,000 times.
