-- it is OK to use laser technology lamina of turbine of spot repair low pressure is in by solder in structural collaboration research center and a project that power plant group supports jointly, university of ability of undergraduate course of Australian Melbourne Si Wei (Swinburne University Of Technology) the Siweiben that belongs to industrial academy (IRIS) the technology that developed to be used at the spot to maintain. This technology used high power laser and fiber-optic the leading edge that will lamina of turbine of spot repair low pressure is worn away and be corroded. When movement wear away badly the service life of the lamina of low-pressure vapour turbine that restricted power station. And service life is very important to a power station. Use this new technology, predict to be able to think a power station costs about 10 million dollars during managing inside whole operating age shutdown. The blade leading edge that laser has repaired changes the lamina of tall twist is very costly, accordingly, emphasis focal point depends on development can lengthening the technology of these blade safety service life. This can forging through using solder to receive the leading edge of blade is protected will come true. On the tradition, this safeguards an operation to need to come down blade from the discharge on rotor, next mount prevents fender newly. What this brought about a dynamo is long shutdown, cause severe loss accordingly. This new development makes the fireproof alloy of these protection defends layer (normally by cobalt / chromic alloy is made) , can be gotten on to blade by spot frit Fu. This process used high power fiber-optic and optical transmission laser, alloy realizes treatment application with pulverous shape. The beam of light that gets from the laser of high power diode of Laserline company is passed fiber-optic be transmitted the surface, beam of light makes pulverous melt, make its fuse on blade, this generated to fight cankerous coating thickly with respect to the blade area that needs in place. The powder of this special development carries nozzle and laser to transmit optical parts of an apparatus to be installed to be on a manipulator, this manipulator makes coating in the blade area of need according to the appearance of blade. This technology is in in TXU company recently the power plant of Torrens island (Australian Adelaide city) the test that have, included introduce diode laser from IRIS, mechanical equipment, and alloyed powder end carries a system, repaired a large number of low-pressure turbine lamina on rotor at the same time. This spot that the technology realizes a few element that take out from inside exercise process hard very likely maintains turbine room. As a result of relatively compositive, portable, high-power, the development of efficient laser illuminant, this technology begins to become a possibility in a few years of ability in the past. In addition, the watch with this effective job understands the value of true cooperation, here, come from research center of research organization, collaboration (the technology that the expertise of sponsor of CRC) , industry is gone to integratedly to come along to develop and realize this innovation. Field test is successful, people is continueing to study new applied way at present. This research is the one part that the strategy of IRIS studies, the strategic goal of IRIS is those who become the research inside industrial domain to make plan is main offer should square, provide very successful platform to use research and technology.
