1DESCRIPTION OF THE HARDNESS TESTER
1.1Purpose of the Hardness Tester
The hardness tester is designed to perform on-the-spot measurement of structural carbon steels in Brinell (HB),
Rockwell (HRC) and Vickers (HV) (main) hardness scales by means of dynamic (contact impedance) method.
The hardness tester is designed to perform (referential) hardness check of structural carbon steels in Rockwell (HRA),
Rockwell (HRB) and Shore (HSD) hardness testing scales —by means of measurement results automatic conversion
from main hardness scale units into respective hardness units according to user’s or manufacturer’s Tables.
The hardness tester is designed to perform (referential) checking of ultimate tensile strength (МPа) of pearlitic
structural carbon steels –be means of measurement results automatic conversion from Brinell (HB) hardness scale
into respective units according to Table.
The hardness tester is designed to perform hardness check of metals and alloys which differ in properties from carbon
structural steels.
The hardness tester may be used to perform hardness check of:
Heat-resistant, corrosion-resistant, stainless, tool and other types of steels;
Non-ferrous metals and alloys;
Process-specific cast irons;
Strengthening and other layers which are coating the steel articles (cementation, nitrogenation, HFC hardening etc.)
Surface deposits and galvanic coatings (chrome etc.);
Articles made of fine-grained materials (during local investigation of materials properties).
If mechanical-and-physical properties of material under check differ from carbon structural steel properties it is
supposed that measurements will be performed after set up of additional calibration (or additional scale) made by the
device user with hardness samples made of respective material or at manufacturer’s production facilities on user’s
request.
The hardness tester is intended for use in laboratory, shop and field environment.
1.2Hardness Tester Operating Principle
Hardness tester operating principle is based on UCI (ultrasonic contact impedance) method.
Basic components of the hardness tester are: sensor and electronic sensor data conversion and measurement data
processing unit.
The metal shaft forming a part of the hardness tester has a diamond pyramid fixed on its and. The shaft is oscillating
with its own resonance frequency. Load created by the user’s hand enables the diamond pyramid to penetrate the
material and to change the shaft’s resonance frequency. Variation of shaft’s own resonance frequency is proportional
to shaft-into-material penetration depth. Since shaft-into-material penetration depth is the hardness factor one can see
dependence between F (variation of shaft’s resonance frequency) and H (material hardness): H = f (F)
The hardness tester electronic unit receives frequency signal from the sensor, converts it into hardness units,
withdraws measurement results to the display and performs statistical processing and other functions of particular
hardness tester.
1.3Hardness Tester Functions

1.5Hardness Tester Sensors
The hardness tester incorporates a sensor and an electronic unit which is processing the signals transmitted from the
sensor. Delivery set of the hardness tester may include additional sensors –on user’s request.
Sensors are designed to form the frequency signal which is transmitting information regarding hardness of article
under check.
Sensor is functionally incorporating a casing and a protective cap (ref. Figure А).
Inside the casing there is a resiliently pressed steel shaft with a diamond pyramid and a limit switch which is, being
closed, gives a resonance frequency measurement command. Piezoelectric plates connected with the shaft are
designed to excite and to receive the shaft oscillations.
The cap is designed to protect the shaft from overload and from touching it by foreign particles or user’s hand in the
course of measurements. Where measurements should be performed in hard-to-reach areas it is allowed to remove
the protective cap.

1.6General Information
Principle of hardness tester operation is based on ultrasonic contact impedance method –dynamic method of
hardness measurement. Unlike hardness testers based on static principle of operation (stationary hardness testers)
the measurement results are affected not only by metal properties revealed during plastic deformation of metal but
also by other mechanical-and-physical properties. Basically –by modulus of elasticity of metal under check (Young's
modulus
Recommended plate parameters are as follows:
- Mass and thickness —definitely exceeding minimum mass and thickness of article under check.
- Roughness –minimum possible. Optimal - maximum Ra 0.4 µm;
- Non-flatness - maximum 0,005 mm;
- Modulus of plate metal elasticity (Young’s modulus)
Depending on the type of probe used and article hardness the sensor pyramid is penetrating the article at different
depths plastic deformation of metal takes place at considerably larger depths. It is recommended to measure
hardness of the layer with thickness which is minimum by 5 times exceeds pyramid penetration depth.
