Abstract
As regards innovative materials, super-heat-resisting materials are under development for steam turbine rotors, integrated high/low pressure rotors, and 43-inch-long blades, all for high-efficiency ultra-supercritical pressure thermoelectric power generators and turbines which are compact in size. A 12CrMo-base steel has been developed with its creep strength augmented for rotors to turn at 600-650{degree}C, the alloy composition optimized and the carbide contrived for stable work at such high temperatures. For the construction of the 43-inch-long rotors, an Nb-containing high-strength 12Cr steel has been developed for the achievement of a tensile strength of 1275MPa. As for high-temperature gas turbines, they are now provided with heat-insulating coatings, and single-crystal moving blades, for example, are used for combustors with their outlet temperature as high as 1400{degree}C, and efforts are being furthered to realize blades capable of operation at 1500{degree}C. There is a technology, basic and applicable to all, of determining the heat caused deterioration of insulating materials for the prediction of service life. Furthermore, studies are under way for the development of surface coatings (protective oxide films, etc.) and anti-corrosion technologies, such as inhibitor-aided treatment and corrosion control of cathodes. A highly reliable bonding technology not to damage materials is also under development. 2 refs.,
