異なることが分かる。FIG. 2 is a cross-sectional photograph of the sprayed coating thus obtained. It can be seen that there are many voids near the coating surface and the surface roughness is large. However, this can be sufficiently removed by a polishing process. It can be seen that the coating near the base material is dense and dense, which is completely different from an atmospheric plasma sprayed coating or a reduced pressure plasma sprayed coating.

Twin crystals were observed at the grain boundaries and within the grains, indicating that the powder solidified after complete melting. Such a phenomenon is not observed at all in other thermal sprayed coatings mentioned as prior art. The powder is so hot that it completely melts, so
The temperature of the base material also rises accordingly. Therefore, the boundary between the coating and the base material is metallurgically bonded, and therefore the adhesion strength of the coating is high.

値である。FIG. 5 shows that the reduced pressure laser sprayed coating of nickel formed in an argon atmosphere has an extremely low coefficient of friction and has extremely excellent performance against repeated sliding motions. This value of the friction coefficient is smaller than the value of the friction coefficient of the surface of the phosphor bronze block material, which is said to have excellent self-lubricating properties.
この理由は、被膜の酸化がないことと、被膜中の気孔が
少なくかつ被膜が強固であることに因ると考えられる。The reason for this is thought to be that there is no oxidation of the film, there are few pores in the film, and the film is strong.
