CLEANING METHOD FOR TURBINE AIRFOILS BY ULTRASONICS

摘要

A cleaning method for gas turbine engine (10) airfoils (30) includes a step of immersing an ultrasonic agitator, such as a welding horn (60), into a tank (52) with a cleaning solution (54) and a step of directing the ultrasonic agitator onto the portion of the airfoil (30) having the crust layer. A subsequent step of high pressure water jet spray removes the crust debris. The cleaning method of the present invention significantly increases the power density of the ultrasonic cleaning.
