法の開発は今後の１！要な研究課題である。Until now, various thermal spraying methods such as gas thermal spraying, plasma thermal spraying, and wire bombardment spraying have been developed, and research is being conducted toward their practical application. However, in either method, the types of thermal spray materials that can be applied are limited, and there are limits to the atomization of the thermal spray materials and the high temperature of the thermal spray materials, which may reduce the adhesion between the thermal spray film and the object to be sprayed. However, the development of a simple thermal spraying method that achieves Z-reliable adhesion is an important future research topic.

する。[In order to achieve the purpose of composition of the invention, the inventors et al. As a result of extensive research into thermal spraying methods and thermal spraying equipment suitable for obtaining thermal spray coatings with excellent adhesion, we have found that the most important thermal spraying conditions are high IW of the thermal spray material, and a high energy density beam. We have discovered that it is possible to non-metalize metals that have been activated at high temperatures by lasers by using laser beams, and by adjusting the atmosphere, and based on this knowledge, we have developed the present invention. I was able to complete it. That is, the gist of the present invention is that the metal wire is heated by the laser beam while being continuously fed through the hole of the mirror toward the convergence area of the laser beam, and when it reaches the convergence area of the laser beam, The tip of the wire reaches the maximum temperature and melts,
The generated molten metal is made into particles using various gases and blown toward the object to be sprayed, or the metal components and gas are reacted while being blown toward the object to be sprayed, and the laser beam is reflected by a mirror. It consists in a thermal spraying method using a laser to obtain a thermal spray film of various components on the surface of the object to be thermally sprayed, which is heated by a laser beam.

、被溶射物に向けて運ばれてこれに衝突する。A laser beam (2) guided from a laser generator is converged by a condensing lens (2) to obtain a convergent portion (2) of a high energy density laser beam. Place a mirror ■ on the opposite side of the lens across this. A hole (2) is provided in a part of the mirror, and a metal wire (2) is continuously fed through this hole toward the convergence section. The wire is heated by the laser beam as it moves from the low energy density area of the laser beam to the high energy density convergence area (■), and when the wire tip reaches the above convergence area, the wire tip reaches the highest temperature. reaches and melts. The molten metal is made into fine particles and blown away by the gas ■ supplied from the gas nozzle ■ provided near the convergence part ■, and becomes flying particles O that are directed toward the object to be sprayed by the gas flow O. It is carried and collides with this.

するととも可能である。The laser beam 0 reflected by the mirror heats the surface of the object to be sprayed, and the flying particles O collide with it.
For example, it adheres strongly to the object to be thermally sprayed and forms a sprayed film O on the surface of the object to be thermally sprayed. The figure shows an example when the object to be sprayed is moved in the direction of the arrow, and a parabolic mirror is used as the mirror.
A case is shown in which the laser beam mQ) reflected by this irradiates the vicinity where the flying particle O and the object to be sprayed (2) collide. The irradiation position can be adjusted so that it can be used for preheating the object to be sprayed or reheating the sprayed film, etc., depending on the conditions when spraying the film, and the irradiation energy density can be adjusted depending on the conditions when spraying the sprayed film.
It is possible to adjust the intensity by changing the strength of the flame spraying object O and the position of the object O to be thermally sprayed.

Since reactive gases such as nitrogen and hydrocarbons, or mixed gases thereof can be arbitrarily selected, thermal spraying can be carried out without (or while) reacting the molten metal and flying particles with the gas. Therefore, the thermal sprayed film obtained by using a metal wire can be a metal, a nonmetal, or a combination thereof, and it is possible to easily obtain a thermal sprayed film that is impossible to achieve with existing technology. can.
