| Outline of Final Research Achievements |
The fundamental research on the development of the SiAlON coating technology superior in the abrasion and high-temperature corrosion resistance, that is applicable for boiler tubes for next-generation high efficiency coal-fired power plants, was carried out. New findings on adequate preparation of SiAlON for spray coating, improvement of bonding strength between SiAlON and heat-resistant alloys, and effects of additives on the growth process of deposited layer of the SiAlON in spray coating were obtained. In addition, new technique to clarify dopant distribution in SiAlON in atomic level was developed.
