Perhaps the paper published by Kolyer, Passchier and
Tran (Boeing in Anaheim, CA) in the June 1998 issue of PC magazine (pp
19-21) will help.
They
recommend measuring power density and resulting errosion by tracking the weight
loss with time using aluminum foil (the stuff in your kitchen).
I
tried it a couple of years ago. I don't have the data but as I remember it
seemed to work.

Key
issue is less Ultrasonic Cleaning, than what you clean in....
Aluminum
is virtually attacked by hot water, and anodizing helps, but not a whole
lot.
Ultrasound pumps in energy, and if attack is possible, with
ultrasound it will become VERY possible....
