摘要：In this paper addresses the issue of steam turbine efficiency by discussing the overhaul design of highpressure steam turbine blades. A specific focus on blade profile, material used in the production of steam turbineblades, and the factors that cause turbine blade failure and therefore the failure of the turbine itself. This projectenumerates and describes the currently available technologies that enhance the overall efficiency of the generator andprevent turbine failure due to blade erosion and blade cracking. In particular, this project evaluates the effectiveness ofcertain titanium alloys and steels in resisting creep and fracture in turbine blades. The effectiveness of chemical andthermal coatings in protecting the blade substrate from corrosion when exposed the wet steam will also be addressed.
