Note that a mechanism (not shown) is added to the plasma spray gun to change the distance between the gun and the fiber base material (work) 7 wound around the outer periphery of the spray drum 3. Further, a metal powder supply device D and a thermal spray control device 10 are connected to the plasma spray gun 2 via a piping system g that passes through the container in an airtight manner.

態も向上する。Figure 3 shows the distance between the gun and the workpiece of 7gCm when aluminum is used as the spraying metal and when spraying in the atmosphere and under reduced pressure.
This figure shows the state of the thermal spray coating on the surface of a single fiber when the pressure was varied from 1 to 60 degrees.The coating layer becomes denser in vacuum spraying than in air spraying, and the shorter the distance between the gun and the workpiece, the more dense the coating layer becomes. The state of coating on single fibers is also improved.

条件の設定とコントロールは難しくなる。On the other hand, under reduced pressure, as shown in Figure 4, the plasma jet becomes longer as the degree of reduced pressure inside the container increases (pressure decreases), and the length of the plasma jet increases rapidly especially in areas of low pressure. O For this reason, contrary to the densification of the coating layer,! IJP
The influence of the lasma jet will be greater than that in the atmosphere if the distance between the gun and the workpiece is the same, making it difficult to set and control the spray conditions.

（ｒ。FIG. S shows the relationship between thermal spraying conditions and the tensile strength of single fibers (carbon fibers in this example) dissolved and extracted from the preform after thermal spraying. As is clear from this figure, when the distance between the gun and the workpiece is long, it has almost the same tensile strength as the material fiber, but the distance between the gun and the workpiece is 6gC! r
Below L, the tensile strength tends to decrease rapidly. This is because when the distance between the gun and the workpiece becomes shorter than a certain value, the area to be thermally sprayed becomes hot (r) due to the influence of the plasma jet.
