Abstract
A member covered with a self-fluxing alloy sprayed coating is produced by previously forming a porous ceramic sprayed coating on a surface of a self-fluxing alloy sprayed coating prior to a refusing treatment of the coating formed on a substrate, heating the sprayed coating in an inert gas atmosphere controlled to 1.about.300 hPa or by a high frequency induction heating system and thereafter removing the ceramic sprayed coating to expose the self-fluxing alloy sprayed coating. This member is uniform in the thickness, less in the retention of pores or oxide impurities and has a strong coating property.
