The blade base 1 is made of a material such as aluminum, and the surface facing the muzzle, that is, the central portion of the blade forming surface 15, is covered with a mask 20 made of a metal plate or the like.

切に設定することになる。By igniting the spark plug 8 in this state, a gas explosion occurs in the explosion chamber 6, and the abrasive material sent into the gun barrel 4 is blasted (shock wave) to the blade forming surface 15.
sprayed on. During this spraying, the heat of the explosion melts (or semi-melts) the binder (the abrasive grains do not melt), so the abrasive grains 9 are attached to the blade forming surface by the binder such as tungsten, resulting in so-called thermal spray formation of the blade. It will be destroyed. In this case, the temperature of the blast wave is influenced by various conditions such as the mixing ratio of the combustion gas components, the size of the communication hole 5, and the volume of the explosion chamber 6, but these conditions are such that the abrasive grains do not melt and the binder The temperature must be set appropriately depending on the type of binder used so that only the binder is melted (or semi-melted).

１の移動制御を行う。When spraying the abrasive grains, as shown in Figure 1,
It is also possible to place a blade base 1 with a diameter smaller than the gun caliber fixedly relative to the gun muzzle and repeatedly spray and deposit abrasive grains on the same location on the base 1. If the diameter is larger than the muzzle, as shown in Figs. 2 and 3, the blade base 1 may be rotated relative to the muzzle, or in addition, moved vertically (or horizontally).
The blade base 1 is arranged so that it can be moved (conceptually, diametrically), and the blade base 1 can be rotated little by little for each explosion or a predetermined number of explosions, or in addition, it can be moved up and down (
By moving horizontally) and sequentially shifting the spraying position 18, a sprayed abrasive grain layer with an even thickness can be formed. This movement of the blade base 1 can be carried out more accurately by computer control, and in some cases, a sensor for detecting the thickness of the sprayed layer is provided, and the detected information of this sensor is input into the computer to control the blade base 1. Controls the movement of the base 1.

備えている。In the case of the above-mentioned repeated explosions, the gun barrel 4 is removed from the cleaning gas pipe 12 for each desired number of explosions, in this embodiment, for each field.
Nitrogen gas is introduced into the interior to clean the interior and prepare for the next explosion.

The grain cutting edge 16 protrudes and can form a so-called hub type blade. Further, in this case, for example, if the entire blade base 1 as shown in FIG. 4 is melted, a blade consisting only of abrasive grains 9 will be formed.

Alternatively, the air inside the gun barrel 4 may be utilized and acetylene or other gas that does not contain air (oxygen) may be used as the combustion gas.
さらに、本実施例では、１回の爆発によって約５μの溶

This makes it possible to manufacture Along with this, it is also possible to significantly reduce the price of the blade. Furthermore, since the type of binder used as the base metal is not limited, the optimum binder can be selected depending on the intended use of the blade, and the performance of the blade can be further improved.
