Definitions
- the present invention relates to a method for forming a thermal spray coating on a base material, which is a dense thermal spray coating made of a non-oxide ceramic material by a high-speed flame spraying method.
- the thermal spraying method supplies a thermal spray material such as metal, ceramics, cermet, etc. into a flame generated by combustion gas or plasma arc, softens or melts it, and sprays it on the surface of the sprayed object at high speed.
- This is a surface treatment technique for coating the surface with a thermal spray coating.
- thermal spraying A wide variety of materials can be used for thermal spraying, but on the other hand, because of the high temperature heating and melting process, the thermal spraying material may evaporate and oxidize during the process. If not selected enough, a good quality film cannot be obtained. In particular, for non-oxide ceramics such as aluminum nitride, it is generally considered difficult to select the spraying conditions as compared with other materials, and various studies have been made in the past.
- Patent Document 1 discloses a base material using an explosive spraying apparatus having a combustion cylinder, gas supply means for supplying fuel gas and the like, ignition means for igniting an air-fuel mixture, and powder supply means. Discloses a method for producing an aluminum nitride film.
- an aluminum nitride powder having an average particle diameter of 1 ⁇ m to 5 ⁇ m is converted into a granulated powder of 20 ⁇ m to 60 ⁇ m.
- Patent Document 2 describes a film forming method in which a temperature and a flight speed of aluminum nitride powder are adjusted and an aluminum nitride sprayed film is formed on a substrate by an atmospheric pressure plasma spraying method.
- Patent Document 3 describes a method for forming a coating film on a substrate for a semiconductor manufacturing apparatus by continuously depositing nitride powder particles on a substrate without melting the particles.
- Patent Literature 4 discloses a method in which a raw material powder mainly composed of metal nitride particles having a sublimation property and having no molten phase is dispersed in an organic solvent to prepare a slurry, and the slurry is subjected to flame spraying under predetermined spraying conditions. A method of spraying and forming a film on the surface of a substrate is described.
- Patent Document 1 In the method described in Patent Document 1 in which an aluminum nitride powder having an adjusted average particle diameter is formed by an explosive spraying apparatus, the material used has a large average particle diameter, so that the film cannot be sufficiently melted to form a film or cannot be formed. Even if it does not become a dense film.
- Patent Document 2 In the film forming method of Patent Document 2 in which aluminum nitride is formed by an atmospheric plasma spraying method, the temperature of the frame due to the plasma heat source is extremely high, and aluminum nitride sublimates. Further, in order to improve the density, it is essential to add a rare earth metal ceramic.
- Patent Document 3 states that 90% or more of the nitride powder particles in the formed thermal spray coating are unmelted and deposited, and that this was realized by modifying the thermal spray nozzle of the ultra-high-speed flame thermal spray equipment. However, there is no description of what modifications were made.
- Patent Document 4 powder having a metal nitride particle diameter of about 0.5 to 3 ⁇ m is used. Unless the thermal spraying conditions are set with extremely high precision, as described above, excessive oxidation of the particles may occur. It is difficult to obtain a film having the required composition.
- an object of the present invention is to provide a method for forming a sprayed coating capable of obtaining a dense and high-adhesion coating even when non-oxide ceramics are used as a material.
- the present inventors have studied a method of forming a thermal spray coating by forming a film by colliding a non-oxide ceramic material on a substrate, and found that a high-speed flame spraying method using a material having a predetermined average particle size and particle size distribution. By adopting this method, we succeeded in forming a dense and high-adhesion film, thereby solving the problem.
- the method of forming a thermal spray coating of the present invention is a method of forming a thermal spray coating by depositing a non-oxide ceramic material on a base material by high-speed flame spraying, wherein the average of the non-oxide ceramic material is averaged.
- the particle size is 0.1 to 5.0 ⁇ m
- the particle size distribution of the non-oxide ceramic material is 0.1 ⁇ m or more and less than 1.0 ⁇ m, and 1.0 ⁇ m or more and less than 10.0 ⁇ m. Has one or more peaks.
- the present invention employs the high-speed flame spraying method, it is possible to prevent the non-oxide ceramic material from being excessively oxidized in the process of spraying, and to obtain a thermal spray coating mainly composed of non-oxide ceramic.
- “mainly composed of non-oxide ceramics” means that non-oxide ceramics are the largest in mass units among the components of the thermal spray coating.
- the non-oxide ceramic material has an average particle diameter smaller than that of a general thermal spray material, and includes a relatively large particle group and a relatively small particle group among them.
- the average particle size of the non-oxide ceramic material is 0.1 to 5.0 ⁇ m, and the particle size distribution of the non-oxide ceramic material ranges from 0.1 ⁇ m to less than 1.0 ⁇ m. It has one or more peaks in each range of 0 ⁇ m or more and less than 10.0 ⁇ m. Even if the high-speed flame spraying method is employed, when thermal spraying is performed in an environment containing oxygen (for example, in the air), a slight oxidation proceeds from the outer peripheral side of the particles.
- particles in the range of 0.1 ⁇ m or more and less than 1.0 ⁇ m are mostly oxidized during the thermal spraying process, whereas particles in the range of 1.0 ⁇ m or more and less than 10.0 ⁇ m are only partially oxidized. And the whole is hardly oxidized.
- particles in the range of 0.1 ⁇ m or more and less than 1.0 ⁇ m become binders for connecting particles in the range of 1.0 ⁇ m or more and less than 10.0 ⁇ m. That is, when a non-oxide ceramic material having a small average particle diameter is used, a relatively large particle and a relatively small particle are contained in a certain amount, respectively, so that a relatively small particle can be compared. It functions as a binder for connecting particles having a large target size, and as a result, a dense and highly adherent film can be obtained.
- a volume ratio of a material having a particle size of 1.0 ⁇ m or more and less than 10.0 ⁇ m to a material having a particle size of 0.1 ⁇ m or more and less than 1.0 ⁇ m is 60% or more. It is preferably 90% or less. In this case, it is possible to obtain a denser film having a higher adhesion.
- the non-oxide ceramic material is supplied to the frame as a suspension dispersed in a solvent.
- a suspension high-speed flame spraying method By forming a film by such a suspension high-speed flame spraying method, agglomeration between materials during transportation of the sprayed material is suppressed, and a dense film can be more reliably formed.
- the suspension is supplied to a frame that is sprayed from the tip of the spray nozzle.
- a frame that is sprayed from the tip of the spray nozzle In the case of the internal supply type high-speed flame spraying method, spitting in which the sprayed material is deposited in the nozzle and the deposit is solidified and discharged is likely to occur.
- spitting can be prevented by using an external supply system in which the suspension is supplied to a frame that is sprayed from the tip of the spray nozzle.
- the non-oxide ceramic material may be made of a material containing one or more ceramics selected from the group consisting of carbide ceramics, nitride ceramics, and boride ceramics. These non-oxide ceramics are harder materials than oxide ceramics, but are generally difficult to form by thermal spraying. According to the method of forming a thermal sprayed coating of the present invention, a dense and high-adhesion coating can be formed even with these materials, so that a hard and high quality coating can be obtained.
- the average particle diameter is 0.1 to 5.0 ⁇ m
- the particle size distribution is a predetermined range where the particle size is smaller than 1.0 ⁇ m, and the particle size is larger.

As described above, it is assumed that there is one or more peaks in each range of less than 10.0 ⁇ m. That is, one or more mountain-shaped shapes exist in the particle size distribution in the range of 0.1 ⁇ m or more and less than 1.0 ⁇ m, and one or more mountain-shaped shapes exist in the particle size distribution in the range of 1.0 ⁇ m or more and less than 10.0 ⁇ m. There are more than one.
- the average particle diameter of the particles is defined as a particle diameter (median diameter) at which a cumulative value becomes 50% when a particle size distribution is measured by a laser diffraction / scattering method (microtrack method).
- Two or three or more peaks may be present in each of the range of 0.1 ⁇ m or more and less than 1.0 ⁇ m, and the range of 1.0 ⁇ m or more and less than 10.0 ⁇ m.
- a typical example is a non-oxide in which one peak exists in a range of 0.1 ⁇ m or more and less than 1.0 ⁇ m and one peak exists in a range of 1.0 ⁇ m or more and less than 10.0 ⁇ m.
- Ceramic materials are mentioned.
- a non-oxidized metal oxide having a plurality of peaks in a range of 0.1 ⁇ m or more and less than 1.0 ⁇ m and a plurality of peaks in a range of 1.0 ⁇ m or more and less than 10.0 ⁇ m.

- the average particle size of the sprayed powder made of a non-oxide ceramic material is set to 0.1 to 5.0 ⁇ m, and the particle size distribution is divided into a predetermined range where the particle size is smaller than 1.0 ⁇ m and a predetermined range where the particle size is larger.

- the porosity of the ceramic sprayed coating may be about 0.1 to 5%, but the porosity of the sprayed coating obtained by the method of forming a sprayed coating of the present embodiment depends on the particle size distribution of the sprayed powder. Less than 0.1% can be obtained. An increase in porosity may lead to a decrease in mechanical strength, and, for example, when used in a gas atmosphere, a gas may easily enter the film. Note that the film formation conditions may be set as appropriate according to the substrate, raw material powder, film thickness, manufacturing environment, and the like.

- FIG. 3 is a photographic diagram showing the results of film forming properties. SD in the table is the spray distance (mm). Even if a powder having the same average particle diameter was used, the film was hardly formed by the material A having the single-peak type particle size distribution, whereas the material B having the double-peak type particle size distribution was used.
