Join the Department of Materials Science and Engineering for the next lecture in the MSE Seminar Series featuring Hyun-Ki Kang of Turbo Power Tech in Korea. His talk will focus on gas turbine repair technology.
Gas turbine operates for a long period of time under harsh, cyclic conditions of high temperature and pressure, where high turbine inlet temperature can range from 1273 to 1873K. Therefore, nickel-based superalloys with excellent mechanical properties and resistance to creep, corrosion and oxidation at high temperatures are used. However, when crack-damaged high-temperature turbine components such as blade and vane are repaired by fusion welding, they cause cracks. Therefore, repair technologies using laser cladding and diffusion brazing, which has less heat input into the base material, are being developed.
Kang is a researcher at Turbo Power Tech. In his role as principal researcher, he develops joint technologies to repair crack-damaged superalloy Hot Gas Path Parts (HGPPs) such as blade, vane and combustion parts. He joined Turbo Power Tech in 2021 and spent the majority of his career repairing the HGPPs in gas turbines. He received his master’s degree from the Department of Metallurgical Engineering at Dong-A University in South Korea in 1996.
All UCF faculty and grad students are welcome to attend.
