(3) A coating method in which a metal phase is attached to the surface of each of the carbide powder particles, (4) An organic binder is added to the raw material mixed powder of the carbide powder and the metal powder, the mixture is granulated, and then sintered at a high temperature. Manufactured by a granulation-sintering method or the like,
The particle size distribution is adjusted appropriately before use. In the powder manufacturing method, the powder is made spherical by (4) granulation-sintering method, but becomes irregularly shaped powder by (1) casting-crushing method and (2) sintering-crushing method. In addition, in the coating method, when the metal phase is attached by the spray method, the shape becomes spherical, and when the metal phase is attached and then pulverized, the shape becomes irregular. The irregularly shaped powder has a large ratio of the major axis and the minor axis of the particle, and is not constant, so when this powder is used in the high-speed powder flame spraying method, the fluidity of the powder becomes unstable, The thickness of the flame containing molten powder particles or semi-molten powder particles is not constant. Therefore, the thickness of the thermal spray coating is likely to be non-uniform due to the uneven flow of the powder.

The thickness is also uniform. However, although the thickness of the sprayed coating is uniform, (1) the deposition yield of the powder is low,
(2) The porous thermal spray coating is easily formed, and (3) the powder is likely to be clogged due to the accumulation of powder on the inner surface of the nozzle of the high-speed flame spray gun, that is, the spraying workability is poor.

とから、その比は１．５以下とした。1. Ratio of major axis to minor axis If the ratio of major axis to minor axis of the powder particles, that is, the value of major axis / minor axis exceeds 1.5, the fluidity of the powder becomes unstable and the film thickness of the sprayed coating formed ( Since the maximum sprayable thickness of high-speed flame spraying is as thin as 0.2 to 0.4 mm), the ratio is set to 1.5 or less.

However, if the amount of particles having a particle size of more than 45 μm exceeds 10% by weight, the fluidity of the powder is further improved (faster), but the hardness and abrasion resistance of the formed sprayed coating are reduced, and the generated pores are further reduced. Since the amount of
It was set to 0% by weight or less. In addition, the number of particles having a particle size of less than 5 μm is 2
When the content is more than 1% by weight, (1) the particle size range is widened and the fluidity of the powder becomes unstable, and (2) only the fine powder scatters out of the flame during thermal spraying of the advanced powder type flame, which reduces the powder deposition yield. Yes (it takes time to spray to a predetermined film thickness), (3) oxidation of the sprayed coating surface becomes severe,
(4) Since fine powder that easily melts is deposited on the inner surface of the nozzle to cause clogging, the content is set to 2% by weight or less.

If the average particle size is less than 20 μm, the hardness of the thermal spray coating that is formed becomes too high and becomes brittle, and cracks and peeling easily occur in the thermal spray coating during the subsequent machining process or when the thermal spray coating is used, and further powder adhesion Yield decreases, and the spraying workability deteriorates significantly. On the other hand, if it exceeds 25 μm, the hardness tends to decrease and a large number of pores are likely to be generated, so that the average particle size is 20 to 25

粒子の球形状化が困難である。In order to produce the tungsten carbide type cermet powder for high speed powder flame spraying of the present invention, it is preferable to adopt the above-mentioned granulation-sintering method. Not only spherical powder particles can be obtained by this method, but also the following advantages can be mentioned. That is, in the powder obtained by the granulation-sintering method, 20% by weight or less is changed to W 2 C and W even after passing through a high-speed high-speed powder flame spray gun (WC becomes W 2 C by losing C). It is reduced to W and C is lost by oxidation and diffusion into the matrix), and the hardness, corrosion resistance and wear resistance of the sprayed coating are less likely to deteriorate. On the other hand, in the case of, for example, WC-Co powder produced by the casting-crushing method, W, W 2 C, Co 3 W 3 are contained in the powder particles in addition to WC.
When the WC-Co powder contains a C 2 phase and passes through a high-speed powder type flame, these phases are decomposed and W is increased, and the hardness, corrosion resistance and wear resistance of the thermal spray coating are likely to deteriorate. Further, although the powder obtained by the sintering-pulverization method is unlikely to cause the deterioration of the thermal spray coating due to the decomposition of the W compound, it is difficult to make the powder particles spherical.

Using these powders, high-speed powder flame spraying was performed on the surface of the base material under the conditions shown in Table 2, the adhesion yield of the powders, the fluidity of the powders during the spraying, and the surface roughness of the sprayed coating formed.

The powder adhesion yield was calculated from the weight of the sprayed coating and the weight of the powder used. Regarding the fluidity of the powder during thermal spraying, we observed clogging of the powder at the nozzle and changes in the thickness of the flame containing the flying powder.

で、溶射作業性が良くない。From the above results, the following can be understood. That is, (1) The high-speed powder flame spray powders of Examples 1 to 4 have a spherical shape and a small amount of fine powder of less than 5 μm, so that the powder adhesion yield and fluidity during spraying are high, and Less likely to clog. Further, since the amount of coarse powder exceeding 45 μm is small and the particle size range is narrow, there are no problems such as uneven thickness (roughness), low hardness, and high porosity.
Good spraying workability and spray coating characteristics could be obtained. (2) The high-speed powder flame spray powder of Comparative Example 1 has a spherical shape, but has a large amount of coarse powder of more than 45 μm and fine powder of less than 5 μm, resulting in poor flowability. When high-speed powder flame spraying is performed using this powder, the deposition yield is low, the hardness is low, the surface roughness is rough (non-uniform coating thickness), and the porosity is high. (3) The high-speed powder flame spraying powder of Comparative Example 2 has a spherical shape, but has many fine powders of less than 5 μm and has poor flowability. When high-speed powder flame spraying is performed using this powder, the deposition yield is low, the hardness is low, and the porosity is high. Moreover, the fluidity of the powder during thermal spraying is not very good, and the thickness of the flame is unstable. (4) The high-speed powder flame spraying powder of Conventional Example 1 has a different manufacturing method and an irregular shape with a large major axis / minor axis ratio, and also contains a large amount of coarse powder exceeding 45 μm and fine powder of less than 5 μm, which is fluid. There is no degree. When high-speed powder flame spraying is performed using this powder, the deposition yield is low, the hardness is low, the surface roughness is rough (non-uniform coating thickness), and the porosity is high. Moreover, the fluidity of the powder during thermal spraying is not very good, and the thickness of the flame is unstable. (5) Similar to Conventional Example 1, the high-speed powder flame spraying powder of Conventional Example 2 has an irregular shape with a large major axis / minor axis ratio, and has many fine powders of less than 5 μm and has no flowability.
When high-speed powder flame spraying is performed using this powder, the adhesion yield is low, the fluidity of the powder during spraying is not good, the nozzle is easily clogged, and the thickness of the flame is unstable. The sex is not good.

In a powder having a spherical shape of 0.5 or less, the particle size distribution of the powder is 45 μm.

Therefore, the fluidity of the powder during high-speed powder flame spraying is excellent. Therefore, it is possible to increase the powder deposition yield during thermal spraying and make the thickness of the thermal spray coating uniform, and at the same time improve the characteristics of the thermal spray coating such as hardness and porosity, and prevent nozzle clogging.
