摘要
PROBLEM TO BE SOLVED: To solve the problems that, since the conventional thermally sprayed coating has been porous, fine gaps have been internally present between circular openings and unmelted powders, and, in the case the gaps and circular openings have been connected and continued from the surface to a base material, corro sive components contained in combustion gas have frequently corroded the base material as a substrate, and sufficient corrosion resistance could not impart thereto, and, since special equipment has been needed for heat treatment, the same was not suited for operation in the job site for repair. ;SOLUTION: For sealing circular openings in the sprayed coating, powders essentially consisting of Ni and Cr and glassy powders are mixed, the temperature of the mixture is raised to form into a corrosion resistant composite thermal spray material in which the glassy powders are adhered on the surfaces of the powders essentially consisting of Ni and Cr. Moreover, in the thermal spraying operation, coating is executed by plasma spraying or gas flame spraying, and the same is applicable, to a corrosion resistant member represented by a boiler tube.;COPYRIGHT: (C)2001,JPO
