Cavitation damage of rubber and plastic is revealing.
Clearly, the projection of large magnetic fields from the center of the
collapsing cavitation bubble will have produced a huge hydrostatic pressure
pulse of water as the water is carried forward by the emerging magnetic
field. But if the damage mechanism in cavitation was solely due to a
pressure pulse of the reentrant jet, rubber would be resistant to such a
damage mechanism. The high pressure water pulse should bounce off the
EMF induced chemical reformulation of the rubber is also going on.
Also, if the attractive mechanism that directs the reentrant jet toward the
rubber surface were electrostatic, rubber should also resist that mechanism.
The attraction of the reentrant jet to a rubber surface might well be a
quantum mechanical mechanism.
Interestingly, from this reference:
Nucleation, Growth and Instability of the Cavitation in Rubber
Many times, at the bottom of the well-developed cavities were found
metallic and other types of particles (Figure 10b) such as ZnO2, silica
and CaCO3, which are composed of carbon black and sometimes sticking of
them by creating bigger inclusion.
This is clear evidence of transmutation during cavitation damage in rubber.
