Description
Technical field
The present invention relates to a kind of preparation method of aerolite double-edged sword.Belong to daggers and swords manufacturing technology field.
Background technology
Aerolite be from the earth outside " guest ", be that the universe meteor of uncombusted beyond the earth departs from original running track
Or be scattering into the earth or other planetary surfaces, stone matter into fragment, irony or stone iron mixture matter, also referred to as " meteorite ".
Iron meteorite therein, is the aerolite comprising substantial amounts of Fe-Ni alloy also known as meteoric iron.
Compared with meteoric stone, iron meteorite is quite rare, and 5.7% ratio is only accounted in the meteoritic abundance that falls, but in history
The ratio that they are accounted in the aerolite number of upper discovery is but very big.For meteoric stone, iron meteorite is not because seek
Normal outward appearance, is more prone to distinguish, they are easier to be survived after getting through the earth's atmosphere also more resistant against slacking, and more can be through
By the result of ablation must be lived, therefore it is easier to find large-scale fragment.In fact, the quality of iron meteorite almost accounts for known aerolite
90%, about 500 tonnes.All known big aerolites, including maximum bar meteoric iron suddenly, are all iron meteorites.Chemical composition with iron,
Based on nickel and cobalt, content is more than 95%；Nickel be bound to exist, concentration between 5% to 25%,
In fact, early stage mankind's smelting technique is undeveloped, it is impossible to smelted from iron ore and obtain iron, and earth nature is almost
There is no the presence of fe, be exactly meteoric iron so meteoric iron had been once the exclusive source of iron, it may be said that the iron that the mankind use earliest.
Until modern age, Malaysia gram force scholar's sword in Malay Archipelago area is still had and is manufactured using meteoric iron.Malaysian gram force scholar is liked with falling from the sky or outer space
Iron, one are because iron ore is poor on Malay Archipelago, and smelting iron process is not smart, and two because nickeliferous in meteoric iron, can strengthen blade
Heavily fortified point profit.
But, since the main component of iron meteorite is iron, it inevitably occurs phenomenon of getting rusty.This is also that iron falls from the sky or outer space
Stone casts the major issue that double-edged sword has to take into account that.
The content of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of preparation method of aerolite double-edged sword.
To achieve the above object, the present invention uses following technical proposals：
The preparation method of aerolite double-edged sword, the aerolite is iron meteorite, is comprised the following steps that：
(1) aerolite is crushed and is fragmentated, ingot is smelted into smelting furnace；
(2) ingot is forged under the conditions of 20~30MPa and 1500~1800 DEG C, forging ratio is 1~1.5；
(3) ingot is struck out into several lamellar bodies that thickness is 0.2~0.3mm；
(4) the first lamellar body is randomly choosed from lamellar body to be placed in smelting furnace, 1800~2000 DEG C are heated to, and treats the first lamellar body
After softening, the second lamellar body is put into, and be covered on the first pellet surface, both bond, the 3rd lamellar body is put into after bonding, repeated
Bonding operation, until each lamellar body is bonded layer by layer, 2500~3000 DEG C is to slowly warm up to the programming rate of 2 DEG C/min, is utilized
Pneumatic hammer is forged into plate body；
(5) plate body is polished into double-edged sword shape, is then heat-treated, with mass ratio 2：1 polyvinyl alcohol and three ethanol
Amine mixed liquor is quenched as hardening media, natural cooling, polishing, obtains final product aerolite double-edged sword.
As one of preferred technical scheme, temper, specific method are first carried out before the ingot punching press of step (3)
It is：Ingot after forging is heated to 1000~1500 DEG C, is incubated 4~10 hours, natural cooling.
As one of preferred technical scheme, first it is surface-treated before the lamellar body input smelting furnace in step (4), is
Lamellar body is soaked 2~3 hours in treatment fluid, the treatment fluid is mixed by the component of following weight portion：Sorbierite
6~9 parts of acid anhydride fatty acid ester, 6~9 parts of rosin, 4~8 parts of Triton X-100,5~8 parts of hydroxy benzo triazole gathers
4~6 parts of propyleneimine, 4~6 parts of PEG400,3~4 parts of self-crosslinking acrylic emulsion, 3~4 parts of citric acid, distilled water
25~30 parts.
Used as one of further preferred technical scheme, the preparation method of the treatment fluid is as follows：Weigh each of formula ratio
Component, ultrasonication 20~30 minutes, obtain final product after mixing.
Used as one of preferred technical scheme, the heat treatment temperature in step (5) is 1500~1600 DEG C, and the time is 1~2
Hour.
Beneficial effects of the present invention：
Aerolite is first crushed, is smelted into ingot by the present invention, is then forged ingot, is struck out lamellar body, using lamellar body molten
The method bonded layer by layer in furnace is forged into plate body, is eventually fabricated aerolite double-edged sword.By forging ratio control than relatively low 1 when forging
~1.5, the natural internal structure of aerolite is kept as far as possible, carry out the small-scale optimization of interior tissue and performance.The smelting furnace of lamellar body
In bond layer by layer, promote the molecular motion between adjacent pellets, under the conditions of 1800~2000 in smelting furnace DEG C, molecule diffusion
More active, inner homogeneous more preferably, contribute to the raising of product mechanical performance.Melting in-furnace temperature delays after the completion of bonding work
Slow to raise, further optimization bonds the inner homogeneous of lamellar body so that the plate body mechanical performance of pneumatic hammer forging is more preferable.Plate body is beaten
After wearing into double-edged sword shape, it is heat-treated and Quenching Treatment, the hardening media for being used is mass ratio 2：1 polyvinyl alcohol and three
Monoethanolamine mixed liquor, surprisingly improves the rustless property of product.The present invention was also processed before lamellar body input smelting furnace
Liquid immersion treatment, further increases the rustless property of product.
Aerolite double-edged sword of the invention has splendid mechanical performance and rustless property.
