New composite materials thermally spray powder is developed in order to protect the surface of boiler tube while long period more than up to this time. This powder is so constitute that original sermet is organized from several bolides and inter metallic compounds (patent pending applied for). For the reliable electric power supply, the steam generating boiler is important facility still today. And in boiler operation, one of the most significant problems is the prevention of boiler tube failure. The main destructive processes that ravage boiler tubes are corrosion and erosion. During the last several years, thermally sprayed coating has been applied to the surfaces of boiler tubes. Accordingly, this paper reports on the effects of this developed powder’s coating as compared with these conventional coatings on the prevention of these hot abrasion are tested in laboratory.
