OBJECTS OF THE INVENTION: TECHNICAL FIELD The present invention relates to nozzles for cold sprayers that are used to greatly reduce the adhesion of nozzles caused by the nozzles in the operation, nozzles, and nozzles. Cold sprayer [Prior Art] In the past, in the mold making process of the iron making process or the various metals of the dairy and air-cars ==, in order to make === machine copper, 1, chrome or its parts , electric mine has ==: question _ metal shot, including the iSif method to form a film. This is the HVOF, atmospheric plasma refining, and the like. ^^ 2 falls due to the oxidation in the spray, and the film has a film as a substitute for the film of the film to form a film of "cold spray; prepared as a solid phase sprayer for D. It is expected that the ancient dip, ^" injury and the industry's attention. This kind of cold-sonic jet recording is turned into a savvy body to be super-inputted, and then the raw material powder material that will be conveyed by the mouth will form a skin 臈i, which is the 金二金相2, which will collide with the base material such as 陶陶竞 and supersonic turbulence. A smear of a gold compound and a collision of the state to form a film. Try to shoot on the surface of the substrate so that it is solid-phase and then detail the cold sprayer technology, such as air, such as air, which is supplied with nitrogen, milk, and gas. The mouth is divided into a functioning body for the gas and the heat of the wheel to the raw material powder, and is supplied to the cavity of the cold-free device by the postage of the heater under the charm U.

Yes, the general _man, the carbon shouting arbitrarily - the expansion nozzle of the kind of ceramic mouth, preferably the cold sprayer spray comprises a cold-scale nozzle device of the present type, which is characterized by a gas mechanism for conveying gas; The nozzle is used. m is more than the above-mentioned - cold spray [effect of the invention] cold and cold spray with spray spray _ long life to reach cold ^, 1 此 mouth this no frequent replacement of cold 啧 Lin cry 4 pottery ' The inner peripheral wall surface of the nozzle for the cold sprayer related to βΛ明 is substantially fogged; = pickling treatment. Therefore, it is assumed that if the raw material powder is attached, the advantage of removing the attached raw material is easily obtained.实施 [Embodiment] The best mode for carrying out the invention will be described in detail. 1 is a cross-sectional view showing an embodiment of the nozzle of the present invention. The sleek 1 towel, the cold scorpion H, is made up of a conical compression portion lb having a tip end of the nozzle inlet end and a cross-section of the cross-section of the product. The nozzle for the two misters according to the present invention may have any other shape as long as it has at least the compressed portion Ib and the expanded portion lc. For example, a narrow throat may be provided between the compressed portion 1b and the above-described expansion portion lc, or a cylindrical parallel portion may be provided on the nozzle side of the expansion portion 1c, IP080245/0PGK00011 - 〇p 8 200911383.

If it is so, it is damaged by the county, the defect, etc.; 4 the wall portion is not easily caused by the inner wall of the expanded portion lc, and the field is excellent. Cold-filled silk, it is very easy to be cut into ceramics -3⁄4 and so on, and the mouth of the mouth is blocked. 'If the part is made of nitrogen powder, the cold mouth mist is caused by the powder of the nozzle, and it is necessary to use nitrogen in the original surface. The inner peripheral wall portion of the expansion portion k may be used as the other portion of the i-jet portion 1b or the like which is conventionally used. The wall surface is also blocked by nitrogen. The cold spray caused by the attachment of the leaf injury The mist is made of a nozzle bismuth ceramic, etc., and is formed into a 35-yy yv, and the entire nozzle 1 of the mist is formed by nitrogen outside the window. The economical viewpoint is better. There is no special restriction on the single-material system of nitriding, and it is better to choose the method of making _ and Z p le, etc., and to conclude: permanent knot, add fiber, Re-sintering to form the shape of the expansion portion.

In Fig. 2, the gas high pressure cylinder 2, the working gas pipeline 3, and the second and third sides are formed. Here, 'the operating gas line 3 and the conveying gas 6α, ο ο ί are provided with: the relay adjusters 5a and 5b, the flow rate adjusting valve 613, the flow meter 7 & 71, and the pressure gauges such as 815, etc. The pressure and flow rate of the working gas and the carrier gas from the compressed gas high pressure cylinder 2 described above are adjusted. In, using 5 to turn the pipeline 3, the heater is heated by the heater of the power supply 9 and heated to the temperature below the dazzling point of the raw material powder, and then introduced into the spray gun chamber 12 of the cold nozzle spray 11 . In the above-mentioned spray chamber I), the pressure gauge 13 and the thermometer 14 are operated, and the surface force of the test surface is pressed against the gfox to 12 °.

Therefore, it is considered that the difference in the constituent materials of the nozzle for the cold atomizer becomes inconspicuous. As a result, from the viewpoint of the squirting and the plugging condition, the embodiment was remarkably superior to the comparative example. The effect of the chaotic body is high. The raw material powder A is close to the mixed state of the liquid, and the colloidal particles of the collision are used in the case of the nozzle of the cold sprayer formed by the non-recorded steel. Significantly, blocked in 3 to 4 minutes 'cannot operate the cold sprayer. On the other hand, in the case of the cold spray H nozzle formed by the tantalum nitride ceramic, the yttria ceramic, or the tantalum tantalum ceramic as shown in the example, it is difficult to cause the adhesion of the raw material particles to the wall surface, and the continuous operation is performed for 30 minutes. Sprayer, no nozzle blockage occurred at all. x [Industrial Applicability] According to the cold sprayer nozzle of the present invention and the cold sprayer device using the cold sprayer nozzle, the adhesion and origin of the raw material powder to the nozzle during the operation of the cold sprayer can be made. The nozzle clogging caused by the adhesion of the raw material powder is greatly reduced, and the life of the nozzle can be extended. Thus, there is no need to change the mouth frequently. Therefore, the present invention is extremely useful for the practical use of cold sprayer technology. Further, since the inner peripheral wall surface of the nozzle for a cold sprayer of the present invention is basically a ceramic material, it can be treated by pickling. Therefore, even if the raw material powder adheres to the inner wall surface of the nozzle for the cold sprayer, it can be easily immersed in the acid solution, and the raw material adhering to the inner peripheral wall surface can be easily removed, and the convenience of repeated use is high.
