Abstract
The invention discloses a high-temperature-resistant metal ceramic die material which is prepared by melting and casting the following materials in percentage by mass: 4 to 12 percent of chromium, 3 to 5 percent of cobalt, 1 to 3 percent of molybdenum, 5 to 10 percent of zirconium dioxide, 2 to 8 percent of titanium carbide, 5 to 15 percent of aluminum sesquioxide and the balance of tungsten. The prepared high-temperature-resistant metal ceramic die material has high red hardness, high thermal stability, high abrasion resistance and high high-temperature resistance; moreover, a ceramic phase metal oxide composition of zirconium dioxide/titanium carbide/aluminum sesquioxide/silicon carbide is added, so that the toughness, thermal shock resistance and quick cooling and heating resistance of a die are greatly improved, the mechanical strength of the die is greatly strengthened, and the service life of the die is remarkably prolonged, and can maximally exceed 20,000 times.
Description
Technical field
The present invention relates to engineering materials manufacture field, particularly a kind of refractory metal ceramic die material.
Background technology
Mould is the important tooling of each department of national economy, enjoys the good reputation of " mother of industry ".Mould molding has that efficiency is high, quality good, save material, many advantages such as to reduce costs.According to statistics, the products such as aircraft, tank, automobile, tractor, electrical equipment and electrical, instrument more than 60% part, the products such as bike, washing machine, refrigerator, electric fan, air-conditioning, photographic camera more than 85% part, all use die production.Do not have modern industrial development without mould, mould industry is all paid much attention in countries in the world.
Affect die life because have: project organization, shaping and manufacturing process, the selecting of moulding stock, thermal treatment process and surface strengthening, lubrication and working service etc.In the factors of mould invalidation, and the inefficacy that cause improper due to mould material, accounts for 50%.As can be seen here, correct with material to playing vital effect die life.
Traditional moulding stock mostly is metal alloys material, but in recent years, along with the development of processing industry grows, it is also proposed more and more higher requirement to the quality of mould.Maximize to pursue enterprise profit, people constantly attempt producing a kind of high life resistant to elevated temperatures high-quality mould, drop into overhead cost as much as possible.But traditional alloy mold general life-span under high-temperature work environment is not high, damage easy to crack under high temperature and long term wear.
Summary of the invention
For the deficiencies in the prior art part, the 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 of the present invention is summarized as follows:
A kind of refractory metal ceramic die material, carries out melting by the material of following mass percentage and cast is made:
Preferably, described refractory metal ceramic die material, carries out melting by the material of following mass percentage and cast is made:
Preferably, described refractory metal ceramic die material, carries out melting by the material of following mass percentage and cast is made:
Preferably, described refractory metal ceramic die material, the temperature range of described melting 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 obtains not only has excellent red hardness, thermostability, wear resistance, anti-oxidant and high-temperature stability, and add this ceramic phase oxide-metal combinations of zirconium/carbon dioxide titanium/aluminium sesquioxide/silicon nitride, drastically increase the toughness of mould, physical strength, heat-shock resistance and anti-rapid heat cycle performance, significantly increase the mold use life-span, the highest work-ing life is more than 20,000 times.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, can implement according to this with reference to specification sheets word to make those skilled in the art.
This case proposes a kind of refractory metal ceramic die material, carries out melting and cast is made by the material of following mass percentage:
Wherein, zirconium/carbon dioxide titanium/aluminium sesquioxide/silicon nitride is sintering metal phase material, and it has the advantage of metal and pottery concurrently, and their density is little, and hardness is high, high temperature resistant, and thermal conductivity is good, can not the embrittlement because of suddenly cold and hot.Aluminium sesquioxide and zirconium dioxide have high temperature resistant, the advantage such as chemical resistance of concrete, high mechanical strength and high thermal conductivity, and titanium carbide and silicon nitride have high temperature resistant, superhard, the feature such as heat-shock resistance and good high temperature creep.
Add chromium, cobalt and molybdenum in the material, be in order to cermet material melting after play more excellent physicals, make to be in phase transformation eutectic point during material solidification, be convenient to control moulding process, reduce Mould Machining cost.Manganese can regulate the critical quenching rate of material, increases the stability of material self.Tungsten, as the main body of material, can promote mechanical strength and high temperature resistant property, also can improve the toughness of material, hardness, wear resistance and anti-rapid heat cycle ability simultaneously.
In the preparation, by above-mentioned formula by after each raw material mixing, carry out melting and cast respectively, the temperature range of melting is preferably 1630 ~ 1750 DEG C, too low, causes raw material fully to merge; For ensureing the mobility of melting rear raw material, when pouring into a mould, its temperature range is preferably 1310 ~ 1390 DEG C.Annealing process after being cast then uses the conventional process of this area.Obtained moulding stock tensile strength > 4500Mpa, impelling strength > 70J/cm
2, HRC > 70, high temperature life > 20,000 times.
