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

Development and manufacturing of non-
destructive testing equipment and system
a permanent spherical indentation is produced in the surface. This
plastic deformation leads to a loss of energy of the impact body and
thus to a lower speed after the actual rebound phase.
The speed ratio is determined exactly at the moment of
impact/rebound by means of the special signal processing. The
speed ratio is therefore unaffected by the impact direction. As
opposed to this, other rebound hardness testers require presetting
of the impact direction in fixed steps (influence of gravitation on the
speed ratio) - which constitutes a considerable disadvantage with
frequently changing test positions.
5.2. UCI method
The Vickers diamond is fixed to the tip of a round metal rod. This
metal rod is excited, to its resonant frequency of approx. 78 kHz,
into longitudinal oscillations. When the Vickers diamond contacts the
sample surface, the resonant frequency will change. This change
happens in relation to the size of the indent area from the Vickers
diamond. The size, in turn, is a measure for the hardness of the
tested material. Resonant frequencies can be measured very
accurately. This is why the UCI method is suited to make the
evaluation of Vickers indents, and thus of the complete test
procedure, so much easier and quicker.
There are also two additional advantages:
- the measurement is made under load. (No impairment of the
measurement due to elastic resilience);
- the hardness measurement is based on the area of the indent and
not on the length of the indent diagonals.
The measurement is thus less affected by surface roughness; even
gunmetal-finished surfaces can be measured.
Concerning the UCI method, the measurement value is also
dependent on the Young’s modulus of the material.

7.2. Choice of the measurement method.
7.2.1. Rebound method of measuring hardness is appropriate for:
- testing objects weighing more than 5 kg and a wall thickness more
than 10 mm;
- massive products, products with a coarse-grained structure, forged
and cast products;
- testing objects with minimal preparation of the surface.
7.2.2. UCI method of measuring hardness is appropriate for:
- testing objects with low mass and small wall thickness;
- testing objects with a glossy surface (with special requirements to
the minimum size of the imprint);
- surfaces of the testing objects with hardened layers.
8. Operation
8.1. Preparation of the test material.
The surface must be clean and free of oil, grease and dust.
The surface roughness of the material should meet the requirements
of a specific probe (paragraph 3.8).
8.2. Features of the methods of measurement of metal hardness:
8.2.1. UCI method:
Distinct reading variations may especially occur with a mass lower
than 0.1 kg and a specimen thickness of less than 1 mm if the test
material is excited to resonance or sympathetic oscillations.
Otherwise, such test materials must be fixed to a solid base, e.g.
using a viscous paste. The same applies to the hardness test
blocks.

Development and manufacturing of non-
destructive testing equipment and system
8.2.2. Rebound method:
With smaller and less heavy test objects, the impact effect of the
impact device may cause vibrations which could produce distorted
measurement results.
- Test objects weighing less than 2 kg must in any case be fixed to
the support using couplant so that there are no any vibrations.
- Test objects weighing between 2 kg and 5 kg must be placed on a
large metal support (e.g. a table) in such a way that they are not
moved or caused to vibrate by the impact.

11. Calibration
11.1. Main calibration
The calibration of the UCI probe is stored in the probe’s memory.
So, you have to calibrate each UCI probes (for example probes with
different load 10N, 50N or 98N) separately.
The calibration of the Leeb probe is stored in the memory of the
electronic unit. So, after changing the Leeb probes, you have to only
check the measurement accuracy, but not to recalibrate the each
Leeb probe separately.
11.1.1. Calibration of the UCI probe
To calibrate the UCI probe you will need 3 samples of material with
a known hardness. Hardness range should be wider than the
hardness of the materials which will be measured (The values
should be the maximum or more, minimum or less and average).
Select in the main menu Calibration:
Each of the scales can be calibrated to 11 conventional materials:
Steel (ST), Alloy Steel (AST), Stainless steel (SST), Cast Iron (CI),
Nodular Iron (NI), Aluminums (Al), Brass (BRS), Bronze (BRZ),
Copper (CU), User material 1 (U1), User material 2 (U2).

For recalibration any of these presetted calibrations, you have to
perform one or two point user calibration for the Steel/HLD cell
(press “SCALE” key), because all available scales are converted in
accordance with ASTM E140 from the basic Leeb scale.
In order to perform one or two point user calibration, follow the same
instructions as for user calibration the UCI probe (See paragraph
11.2.).
11.2. User (additional) calibration (UCI probe)
Each of the saved main calibration may be further corrected.
Additional calibration is recommended in the following cases:
- If the measurements of the device on the samples are constant,
but differ from the nominal value of the standard block;
- After extended storage (more than 3 months.);
- After intensive operation;
- With a significant change in the operating conditions (temperature,
humidity, etc.).
For the calibration of hardness scale needed one (single-point
calibration) or two (two-point calibration) standard hardness tests
samples with the maximum and minimum values for the controlled
range of the hardness.
