To improve gas turbine performance, it is essential to decrease back flow gases in the high-temperature combustion region of the turbo machine by reducing the shroud/rotor gap. An abradable seal coating will function effectively. The present work described an advanced detection technology and test rigs to study abradability of the seal coatings. Several early used analytical methods were also reviewed in the work as comparison,like NASAPWA and Sulzer Innotec, have developed abradable test rigs and specified different experimental parameters by simulating the determined working conditions. Thence, suggestions to further develop evaluation methods for seal coatings were proposed and discussed.
