Abstract (en)
[origin: WO8401528A1] A vapor pocket (PV) is formed at the contact of a surface to be eroded (S) by an active ridge (D2) which is the edge of a deflector (D) which receives a high speed water jet formed by a nozzle (B) and deflects that jet in parallel to said surface. Application to the pickling of a polluted surface.
