Laboratory of Surface Technologies and Degradation of Materials (Branch Office in Pilsen)
Department: Department D 4 - Impact and Waves in Solids
Head: doc. Ing. Petr Hora, CSc.
In the Laboratory of Material Diagnostics, we focus on the study of complex issues of material degradation. Metallic materials are mechanical and corrosive loads with simulation of degradation processes. Polymeric and composite materials are degradation processes of thermal aging, the action of moisture and the influence of radiation simulated by solar radiation. The state of degradation is checked retrospectively by sensitive analytical methods. The study of degradation in close feedback on the development of technological processes of surface treatment serves to improve the resistance of materials to various above-mentioned degradation processes.
ELASTOCON EB 23 WITH RELAXATION EQUIPMENT ELASTOCON EB 02
Temperature chamber enables simulation long-term temperature ageing of polymeric materials with measurement of relaxation processes during heating. The measurement is performed step by step for the evaluation of degradation involving changing namely mechanical properties.
Q-LAB CRH 600 HSC
Corrosion chamber enables testing of corrosion resistance of materials (before and after processes of surface treatment) using salt fog or shower of salt solution under defined humidity and temperature. The measurement is performed step by step for the evaluation of initiation of corrosion and expansion of corrosive degradation.
Q SUN XE3HS
Sun chamber enables simulation of radiation ageing of materials under combination stress sun radiation, temperature and humidity with application on different kind of polymeric materials including thin films. The measurement is performed step by step for the evaluation of degradation involving changing namely mechanical properties.
ELECTROPLUS E10000 LINEAR-TORSION INSTRON WITH CLIMATIC CHAMBER, HEATING OF SAMPLES AND CHAMBER FOR LIQUID ENVIRONMENT
ElectroPlus E10000 is used for testing of mechanical properties by static (tensile, pressure and torsion) and cyclic loading for the evaluation of fatigue behaviour with possibilities to take into account also higher temperatures and influence of liquid environment. Mechanical testing is performed for the evaluation of properties samples with thin films or after corrosion degradation or after ageing processes (polymeric materials).
VEGA3 SB-EASYPROBE TESCAN WITH MICROPROBE
Scanning Electron Microscope enables the evaluation of systems thin film – substrate – structure, chemical composition, adhesive cohesive behaviour after scratch and static indentation, fractures after tensile and torsion tests during static and cycle loading, corrosion degradation and other analyses connected with surface treatment processes, corrosion and ageing processes.
NST3 ANTON PAAR
NST3 is used for testing of mechanical properties and behaviour of systems thin film – substrate created namely by Flexicoat 850 - for control of surface treatment processes and their modification. In the range of study of ageing processes of polymeric materials the NST3 is used for the evaluation of changing of surface properties of polymeric materials before and after ageing processes depending on temperature, exposed sun radiation and humidity. The evaluated properties for optimization of systems thin film – substrate are namely hardening of surfaces, adhesive cohesive properties and elastic-plastic behaviour with depth sensitivity.
FLEXICOAT 850 – WITH COMBINATION DEPOSITION PROCESSES CARC+, SPUTTERING AND PACVD
Surface treatment by different methods as PVD – ARC, PVD – UBM, nitriding and PACVD and their combination for the creation of different type of thin films based on used targets, cathodes and process gases. The application enables increasing wear resistance, fatigue resistance, corrosion resistance, biocompatibility and bioaktivity.
