Description

Powder material special for air-based weapon

Technical field

The present invention relates to the nanometer metal powder material, be specially a kind of powder material special for air-based weapon.

Background technology

" sky and ocean are the battlefields in 20th century, and space will become the battlefield of 21 century.Here it is, and each military power of the world all wants the most direct expression of contention control space power.In recent years, the contention of state in the space field such as US and Russia was more and more fierce.They not only make great efforts to develop space war weapon (space-based weapon), and, doing various preparations at the space war that might take place future.

The space war of 21 century is meant the space-based weapon system that utilizes, and is the operation of purpose with contention system Megrez.Usually the space war of indication is meant that with the outer space away from the earth be the operation of attacking and preventing that the battlefield is carried out.It had both comprised the fistfight between the operation both sides space-based weapon system, comprised that also the space-based weapon system is to the strike of earth surface and aerial target and the attack of the space-based weapon system being started from earth surface.Its purpose is exactly the use and the right of eminent domain that will fight for the space field, and deprives the right to use of the other side to space.

The triumphant profit of military scholar Jack of the U.S. is thought, because space war is still brand-new patterns of warfare, the specific example of a battle can be for research under battle conditions, and the outburst form of Future Outer Space war all is a predictability at present basically.But judge that from the battle plan of US Department of Defense with based on the space technology Development Prospect pattern of operation of Future Outer Space war mainly contains three kinds: " destructions " (Destroy), " blinding " (Blind) with " interference " (Jam).

" destruction " is to utilize armament systems directly to smash enemy's space-based weapon system or utilize the space-based weapon system that ground is implemented to hit from earth surface or space." destruction " may be the main patterns of warfare of Future Outer Space war, its employed weapon kind comprises laser, dispose in orbit can be motor-driven the antisatellite missile and the guided missile on ground etc." blinding " utilizes directed energy weapons such as laser, microwave exactly, attacks enemy's spacebased system from earth surface or space, and various optics and electronic instrument in enemy's space-based weapon system are damaged, thereby can't operate as normal.Compare with the operation that with " destruction " is purpose, injuring that this patterns of warfare are subsidiary is less, also can not have much impact to the people's livelihood, therefore comparatively speaking than " humanity " a bit." interference " is exactly on the basis of grasping enemy's space-based weapon system operational parameters, and the instruction of emission identical parameters makes it can not receive normal instruction or operate as normal.This patterns of warfare are more hidden, and cost is less, can also reduce the negative effect that brings to one's own side.

Because space war is a pattern of operation that is full of technology content, must rely on stronger space technology level, so space war also just imagination and plan at present, counterspace operations equipment (space-based weapon system) is the space war basis of implementing and crucial of relying.

" space-based weapon system " subject matter of existing at present in the world: in recent years, each military power of the world is all at the armament systems of making great efforts the research and development space war, " destruction " system particularly because " blinding " in main three kinds of patterns of operation of space war (Blind) and " interference " (Jam) be not difficult to develop in present basic space technology.So at present in the world main research be " destruction " system in the space-based weapon system.

Because international community in recent years, to research and development on space and layout space-based weapon system, make space become the future battlefield that war wind and cloud gathers and oppose energetically, so that each military power plans to research and develop one after another is so-called " green space-based weapon system " (non-hot weapons system).

But, at present world technology strength also can't reach the dual-use function that can " green " can " destroy " again, and in the space war in future, " destruction " weapon in the space-based weapon system, can't tackle and stop on the earth, and " destruction " weapon is unthinkable to the strike of earth target and " destructions " degree, and its " destruction " ability is much larger than present huge " atom bomb " of power in the world.

The specific embodiment

Embodiment 1, a kind of powder material special for air-based weapon, be by following method preparation, (concrete processing method referenced patent application number is the cutting production technology of metal nanometer powder zero boundry particle of 2006100481685 records,) under-5 ℃ situation, high frequency cutting number of times is set under the true 5500 times situation of per minute to be produced, processing powder grain shape is the nano iron powder dedicated (nano titanium powder; receive a meter Tungsten powder of irregular spheroid, the nanometer lead powder), sub-elect the bigger powder body material of distribution of particles of (500nm is an example) D3=42.21nm D25=262nm D50=500nmD75=677.2nm D97=930.3nm more respectively, use again then that (number of patent application is that 2006101620469 to disclose a kind of metal little, nano particle cladding process), " DQ coats method " continues thickness to ferrous powder granules: the anti-oxidation coating of 1nm-3nm reaches more than 90 hours its anti-oxidization time.

Used cutting machine as schematically shown in Figure 1, cutting machine structure comprises the body that has cooling system, body is provided with charging aperture 2, inert gas entrance 1, (lower end of charging aperture 2) is provided with some cutter groups in body 4, each cutter group comprises two

cutters

5,14 that working face is relative, the working face of

cutter

5,14 is zigzag or file shape, and two

cutters

5,14 are exported the rotating part combinations by separately connecting rod 6,13 and frequency modulation vibrating motor 9 respectively.Cutting machine is designed to the dual-vibration system, and outer VIBRATION DESIGN is the gasbag-type vibrating device, and the internal vibration system is designed to the spring vibration device.The frequency modulation vibrating motor, adopt the mode of frequency modulation to carry out the control of vibration frequency, pass by adjusting rotating speed of motor 1500/minute---6000 biographies/minute, vibration frequency is controlled at 1500 times/minute-6000 times/minute, reach the unlimited cutting of designing requirement---" zero boundry particle patterning method ".Cutting machine is when work, and indoor design adds inert gas and keeps the constant of processing temperature, adds the temperature processing that cooling water is set simultaneously in interlayer.Its operation principle is to do relative motion by two cutters that frequency modulation motor drives each cutter group, make the working face relative motion of two cutters, move mutually in its surperficial zigzag or file shape protruding part then, major diameter feed metal particle about 80 orders-100 order of charging aperture adding is constantly rubbed, collides, pushes, and the effect that reaches at last is to make oarse-grained metallic particles be divided into the small diameter particles object.The surface of cutter is just as the structure on file surface, and its gap is adjustable, so that adapt to the size of raw material particle.After cutting machine work begins, metallic particles powder irregular particle has been carried out N cutting from top to bottom in the motion process between two cutters, certainly the frequency modulation motor rotating speed is high more, the probability that metallic particles is cut in unit interval is also big more, the distribution probability of the metallic particles of the small diameter particles that it processes is also big more, and sorting is got up also easier.Generally to circulate and cut the nano metal powder particle that just can reach more than 80% through six times.

Anti-oxidation coating process; metal powder material is in temperature (100 ℃-310 ℃) and have under the environment of protective gas (N) and produce; to add 10% in the time of processing---the purity oxygen of 15% (volume ratio); forming thickness on the metal powder particles surface is 1nm---the oxide layer of 2nm; then in the high temp tunnel stove; temperature is adjusted between 350 ℃-510 ℃; the metal powder particles material is under this temperature conditions; the surface oxide layer structure begins to soften; under the situation of sealing; inert gas N and He in 4: 6 ratio injection dew point≤6; injection length was controlled at 30 minutes---and 45 minutes, allow inert gas fully be penetrated in the oxide layer on metal powder material surface.
