COATING MATERIAL, METHOD FOR PRODUCTION THEREOF, COATING METHOD, ROTOR BLADE EQUIPPED WITH SHROUD

摘要

The present invention provides a coating material, a method of manufacturing the coating material and a coating method using the coating material that are capable of forming a coating film that retains high abrasion resistance while offering improved oxidation resistance at high temperatures, and also provides a moving blade fitted with a shroud. A coating material is used that comprises not less than 14% by mass and not more than 30% by mass of Mo, not less than 13% by mass and not more than 20% by mass of Cr, and not less than 0.5% by mass and not more than 4% by mass of Si, may further comprise not more than 1.5% by mass of Ni, not more than 1.5% by mass of Fe, and not more than 0.08% by mass of C, and comprises a balance of Co and unavoidable impurities, wherein the material further comprises at least one added component selected from the group consisting of not less than 0.01% by mass and not more than 3% by mass of Y, not less than 0.01% by mass and not more than 10% by mass of Al, and not less than 0.1% by mass and not more than 10% by mass of Fe.
