| 摘要 |
The present invention provides a thermal spraying device with which ignition can be prevented when a large amount of spraying occurs. This thermal spraying device is provided with multiple dispensing units that dispense a raw material powder, with each dispensing unit being connected to a mixture generation means that forms a mixture by mixing a carrier gas and the raw material powder dispensed by the dispensing unit, and a spraying means (40) that sprays the mixture generated by the mixture generation means. The center-to-center distance between the spray holes (41) of these spray means (40) is 1.4-5.3 times the inner diameter of the spray holes (41). |
