PURPOSE: To strengthen a sprayed coating by adopting sealing treatment. CONSTITUTION: At the time of forming a sprayed coating, in the stage in which a sprayed coating is formed to a thickness smaller than the final thickness, sealing is applied to the resultant sprayed coating by using a sealant. After the sealant is perfectly dried and formed into solid matter, the formation of sprayed deposit is further continued. If necessary, this process is repeated, and the strengthening of the sprayed coating by the sealing and densification of the inner part of the coating is performed. By this method, the wear resistance, corrosion resistance, heat resistance, etc., of the sprayed coating can be improved, and the service life of a structural member can be prolonged. |
