Protective coatings produced by high velocity flame sprayings can be useful in combating the hot corrosion experienced in waste incinerators. The D-GUN and HVOF coating processes produce poreless high quality coating layers with strong adherence to substrate materials. Laboratory tests were performed to examine corrosion and heat resistance of several coatings produced by the D-GUN and HVOF processes. From these test results, 50%TiO2-50%Alloy625 cermet coatings were selected and applied to the superheater tubes in a 500C/100ata high efficiency waste-to-energy pilot plant. The coating layer of the final superheater tube disappeared in less than 2,000 hours. On the other hand, the coating layer of the secondary superheater tube showed excellent corrosion resistance compared to substrate tubes of 25Cr20Ni-Nb and other corrosion resistance alloys such as Alloy 625. This paper describes the laboratory corrosion and thermal shock test results of various D-GUN and HVOF coatings, and examination results of coated tubes exposed 6,400 hours in a pilot plant. Keywords: hot corrosion, waste incinerator, high velocity flame spraying, detonation-gun process, cermet material
