摘要: Abstract In this study, Ti-6Al-4V dovetail joint specimens which highly simulate the attachment between blade and disk of fan stages in a certain gas turbine engine were designed used fretting fatigue experiments. The wear mechanism was characterized using bench level experimental method. effect shot-peening on both property evaluated. results indicated that transformed behavior, altered dominant crack initiation dramatically promoted performance specimens. Different reinforcement mechanisms multiple surface modifications created by also analyzed summarized study.
