４＜混合されている。In view of the current state of the conventional technology as described above, the problems that the present invention attempts to solve are that in the method (1), it is difficult to uniformly diffuse fine hard particles in the molten pool; In the method (2), it is difficult to mix the fine hard particles in a uniformly dispersed state into the molten pool on the surface of the surface-coated member. When injecting, extremely advanced technology is required to mix fine hard particles in a uniformly dispersed state into the molten bottle, and it is necessary to use extremely advanced technology to mix fine hard particles into the melting bottle in a uniformly dispersed state. It is almost impossible to form a layer stably. In addition, in the method (2), powder particles which form the matrix structure of the surface coating layer are mixed into the coating material.

いという、ことである。Therefore, it is possible to melt the powder that should take care of the matrix structure around the fine hard particles.Furthermore, when alloying the surface of the surface-coated member and the surface coating layer, Since the fine hard particles of the surface coating layer of the coating member and the material constituting the base structure are mixed into the coating material at the same time, it is easier to form a particle-dispersed surface coating layer than in the illegal methods described in (1) and (2). However, in this method, the surface of the surface-coated member is coated with a coating agent that is a mixture of fine hard particles and matrix structure constituent material powder. (mixing state during coating, dispersion state of fine hard particles during coating after mixing, etc.), the uniformity of the dispersion state of fine hard particles in the particle-dispersed surface coating layer, or the bonding between the matrix structure and fine hard particles. This means that it is not possible to ensure sufficient surface friction and abrasion characteristics such as abrasion resistance and seizure resistance for the structural member according to the purpose of the surface coating treatment.

By projecting and injecting the fine hard particles by a thermal spraying method with a high spray particle velocity such as a plasma spraying method, the bond between the matrix structure and the finely dispersed particles in the surface coating layer of the surface coating member is improved.
Furthermore, by ensuring an excellent dispersion state of the dispersed particles in the matrix structure in the particle dispersion surface coating layer, excellent surface friction and wear properties are achieved.
