5. Principle of operation
5.1. Rebound method
Rebound probe consists of an impact body and the capture. The
impact body has a carbide tip and a permanent magnet for
generating a voltage pulse; the impact device has a spring
mechanism for loading and impelling the impact body, and an
induction coil for detecting the magnet in the impact body. In the
rebound hardness testing method, the speed variation caused by
the impact of the impact body against the material surface is
measured.
The impact energy is adjusted via the spring for the measurement.
The impact body contained in the tube of the impact device is
impelled against the test surface by means of the release button. In
the course of this, the magnet of the impact body induces in the coil
a voltage signal whose height is proportional to the impact phase
speed. The impact causes a plastic deformation of the material and
