The former process is called cavitation erosion and the latter is liquid-droplet erosion...

... It is quite difficult to propel liquid droplets to high velocities without breaking them up, and liquid impingement erosion has become a practical problem primarily where the target body moves at high speeds and collides with liquid drops that are moving much more slowly. Historically, almost all the work...
