Indentation tester Nanotest Vantage
Presentation of equipment

The indentation tester is a device for measuring mechanical properties of substances. We indent the indenter into the surface of the test piece and measure the force F and the indentation depth h. By evaluating the F–h indentation curve, we obtain data on indentation hardness, the indentation elasticity module, the plastic and elastic part as well as yield point. Measurements are carried out in the nano- and micro-area, since we can change the force from only a couple of ten mN up to 30 N. We also perform scratch tests and measure the coefficient of friction. By heating the sample and the indenter up to 400 °C we can define properties depending on the temperature and monitor the time-dependent processes, such as creep.

We can define numerous mechanical properties of all hard substances, especially materials that are air-resistant at testing temperatures of up to 400 °C. At higher loads we obtain the properties of the entire material, at lower loads, however, we measure the properties of thin surface layers as well as microstructural components of only a couple of micrometers.

Electronic device for measuring the growth of cracks in metallic materials MATELECT DCM-2 DCPD
Presentation of equipment

DCM-2 is a modern microprocessor instrument for measuring the depth of cracks in metals during loading. DCM-2 represents the latest version that enables simple calibration and operation.

It uses the method of pulsating direct current (DCPD) which is already a well-established technique and included in the ASTM 647 standard. The technique includes the passing of a constant current through the tested metal and measuring the resulting voltage drop occurring on the sample. The presence of increasing error will change this voltage and by adequate calibration we can obtain an error depth measurement. Characteristic for the DSM-2 instrument is the high stability of current (under 0.01%) according to the set current range as well as operation in 4 voltage ranges from +/-4500mV to +/-45mV with an 0.001% accuracy of the area. The DCM-2 instrument can be synchronized with other measuring systems of servo-hydraulic machines, since it enables synchronization of input voltage from min +/-150mV to max +/-20 V with a frequency from 0.6 Hz to 500 Hz. The measurement can be initiated based on the previously set peak voltage or voltage threshold. Moreover, the device also has BNC outputs, where bits are analogously separated for X,Y and X/Y signals and enable graphical display on the screen with the help of a card.

System for stereo-optical measurement of deformations on material surface GOM Aramis12M
Presentation of equipment

The ARAMIS 12M stereo-optical system enables to monitor movements, deformations and stress on the material surface during stress testing with a recording speed between 25 and 100 images per second with 12 mio measuring points. Based on the DIC (Digital Image Correlation) technique, the system performs a fully automatic measurement of movements and deformations in the observed field from 80 x 60 mm2 to 910 x 675 mm2. The system allows measurement and analysis of 3D movements of the selected discrete points. From the obtained quantities the system calculates stress tensors, movement vectors, speeds and accelerations in individual points. Based on monitoring the deformation response on the surface of spatial elements, the system performs a geometric quantification of points and compares them with points on numerical 3D or/and CAD (Computer Aided Dosing) models. The measuring and control unit controls the measuring process by capturing images and other, to additional digital and analogue signals from other measuring systems and links signals and measuring quantities with the recorded geometry.

Multi-channel potentiostat/galvanostat/impedance analyzer MultiPalmSens4
Presentation of equipment The multi-channel potentiostat/galvanostat/impedance analyzer MultiPalmSens4 consists of 18 independent PalmSens4 potentiostats. All independent channels enable to choose between nine current ranges from 100 pA to 10 mA and have a potential range of ±10 V. They all enable measurements of electrochemical impedance spectroscopy with a maximum frequency of 1 MHz. Each channel is equipped with a memory capacity of 8 GB, which means that measurements are stored automatically. The MultiPalmSens4 multi-channel potentiostat is controlled by MultiTrace software which enables individual or simultaneous use of each channel. The multi-channel potentiostat can also be used as a polypotentiostat. This means that we can use several working electrodes, one auxiliary electrode and one reference electrode in the same electrochemical cell at the same time. In this case, all working electrodes perform the same measurement. MultiPalmSens4 enables numerous voltammetric, pulse, amperometric, galvanostatic techniques as well as potenciostatic/galvanostatic impedance spectroscopy.
