摘要

PROBLEM TO BE SOLVED: To easily change a porosity in the surface of a thermal-sprayed film.;SOLUTION: This porosity-adjusting method includes sprouting a high-pressure fluid 9 onto the surface 1 of the thermal-sprayed film formed by thermal-spraying the droplets 3 of a metallic material for thermal spraying, thereby blowing a part of the droplets 3 which form the thermal-sprayed film, and forming fine pores in the surface 1 of the thermal-sprayed film.;COPYRIGHT: (C)2006,JPO&NCIPI
