である。2. Description of the Related Art For the purpose of surface modification, various materials such as ceramics, cermets and metals are sprayed by a gas spraying method such as flame spraying or explosive spraying as described in JIS H8200. Alternatively, thermal spraying is performed on a substrate surface by an electric spraying method such as arc spraying or plasma spraying. However, thermal spraying
Due to the principle of spraying the material particles in which the material is in a molten or semi-molten state onto the base material to form a film, the problem that the spraying quality of the unmelted particles or particles adhered to the inside of the spray gun falls due to entrainment (spitting) in the product film. Yes, and we must be very careful to prevent it. The reason is,
When spitting defects occur, surface defects such as a decrease in the hardness of the thermal spray coating, a decrease in the adhesion of the thermal spray coating, a peeling of the thermal spray layer, and pit defects due to spitting after the surface finishing process are difficult to repair. This is because

However, frequent maintenance of the spray gun,
Without cleaning, it is difficult to prevent spitting,
This is a problem in stabilizing quality and work efficiency. The problem to be solved by the present invention is to find a method for forming a thermal spray coating that does not cause such spitting defects.

We can find a stable quality and low-cost spraying method that can reduce the finished surface roughness for thermal spraying with large finished surface roughness, reduce the cost of surface finishing machining, etc., greatly improve work efficiency and simultaneously stabilize the quality of sprayed products.

And Ra is 15 μm in the range, and the surface is subjected to dry polishing or grinding , and the films are laminated to form a thermal sprayed coating free from coating defects.

る。As a result of repeated investigations and experiments, the present inventors have found that spitting particles have a small adhesion and can be removed immediately after spraying a film. In other words, the spitting defect is the entrainment of unmelted particles or particles adhered inside the spray gun into the product film, and the mechanism of its occurrence is an internal defect due to the subsequent thermal spray lamination to the adhered spitting foreign particles, and immediately after adhesion. An experimental result was obtained in which the spitting particles immediately after adhesion had very small adhesion and could be removed. Since spitting occurs accidentally, it is difficult to detect spitting occurrence and remove it each time, which is not preferable in terms of work efficiency. Therefore, a method was devised in which light surface processing was performed simultaneously with thermal spraying to constantly perform thermal spray lamination, light polishing and grinding.

り、機械加工を加えたりしないこととされている。 [0007] It is common knowledge that spraying does not involve any modification to the coating during spraying. The reason is that thermal spraying has the drawback of lower adhesion than other surface treatment technologies, and the thermal spray adhesion mechanism is based on the fact that the thermal spray particles mechanically mesh with the base material or the rough surface that constitutes the thermal spray coating. An action that directly leads to a decrease in adhesion due to the casting effect
Do not perform, for example, the surface of the substrate or the surface of the thermal spray coating during thermal spraying may cause grease to adhere,
And do not add any mechanical processing.

経済的に好ましくない。However, as a result of repeated studies and experiments, the present inventor has confirmed that the adhesion is not reduced by a dry surface processing method and by properly maintaining the surface roughness.
The appropriate range is from Ra 1 μm to Ra 15 μm.
If the surface roughness Ra is less than 1 μm, there is no problem in the effect of removing spitting, but the above-mentioned decrease in the thermal spray adhesion is remarkable, and it is difficult to secure a stable film adhesion. On the other hand, if Ra exceeds 15 μm, the spitting removal effect and the thermal spray adhesion stability are not problematic, but the production yield of the thermal spray coating deteriorates.
Not economically favorable.

して極めて有効な方法である。The above-described thermal spraying method of the present invention can not only prevent spitting but also arbitrarily obtain a desired surface roughness after thermal spraying. Conventionally, when the surface roughness of a sprayed product is required depending on the application, a predetermined surface roughness is obtained by polishing or shot dulling after spraying, but according to the spraying method of the present invention, a predetermined surface roughness is obtained in the spraying process. Surface roughness can be obtained, and the cost can be reduced by omitting the steps. In addition, compared to continuous spraying such as plasma spraying, intermittent spraying such as explosive spraying can greatly reduce the finished surface roughness for thermal spraying with a large finished surface roughness, and reduce the cost of surface finishing machining. It is also possible. Further, the present method is not particularly limited in the thermal spraying method and the thermal spray film thickness, and is applicable to all thermal spraying methods. In particular, in the thermal spraying method, supersonic gas spraying using a thermal spray gun having a combustion chamber (jet This is an extremely effective method for models where spitting is likely to occur, such as a coat gun) or an explosive spray gun.
