8. Laboratory of Metallic Materials (within the Department of Metallic, Composite
and Polymeric Materials)

Field of accreditation in 2018
• Optical characterization of colloidal suspension and nanopowders by light absorption
spectrophotometry in the UV‑Vis‑NIR (by using the V570 Jasco spectrophotometer, Japan);
• Characterization of thin films and solid parts with parallel planar surfaces in terms of tribological
and mechanical properties by determining the coefficient of friction and wear rates, respectively
by determining the Vickers hardness, Young’s modulus and elastic contact stiffness by nano /
microindentation and of the critical adhesion / cohesion forces through microscratching (by using
the ball / pin‑on‑disk tribometer and the compact platform with nano / microindentation and
microscratching platform, CSM Instruments, Switzerland);
• Determination of coatings thickness in the range of 100 nm and 50 µm (with the Calotest Compact
system, Anton Paar, Switzerland);
• Determination of the nanoparticle size, size distribution and zeta potential by dynamic light scattering
(DLS) and electrophoretic light scattering (ELS) (by using the device 90 Plus, Brookhaven, USA);
• Analysis of thermal behavior of the metallic powders, ceramics, glass and composite materials, by
using the equipment “ Horizontal dilatometer model L75HS2000C + L75HS700LT”, (Linseis GmbH,
Germania), in the temperature range of: ‑150 – 700°C; RT...2000°C. Determination of the: linear
thermal expansion (βl); coefficient of thermal expansion (CTE); vitreous transition temperature (Tg);
phase transitions; measuring the density and volume expansion of the compacted material from metal
powders; three‑points bending analysis for determining the mechanical stability, the measuring voltage
in the form of fiber materials and metal foils;
• Determination of the mass variations and thermal changes for different types of materials, including
inhomogeneous materials, by using the equipment „Simultaneous thermal analyzer TG‑DSC STA 449
F3 Jupiter” (NETZSCH, Germany) in the temperature range of RT...1500°C;
• Determination of the thermal diffusivity, specific heat and thermal conductivity by using the
equipment „LFA 447 Nanoflash’’ (Netzsch, Germany) for various materials (metals, graphite, coatings,
composites, ceramics, polymers, etc.) in the temperature range of RT...300°C;
• Analysis of the mechanical behavior by using the universal machine for mechanical testing of materials
in static regime, model LFM 30kN (Walter & Bai AG Switzerland). Mechanical characteristics to be
determined: maximum mechanical strength, Rm (MPa); Yield strength, Rp0.2 (MPa); Elongation, A
(%); the modulus of elasticity, E (GPa);
• Vacuum deposition of thin films in order to achieve a thin coating technologies: decorative,
biocompatible optical, anticorrosion, lubricating, anti‑wear, etc. by standard magnetron sputtering or
reactive‑type, by using the technological equipment for processing in vacuum a thin layer of titanium
nitride (BESTEC GmbH, Germany);
• Determination of the gas adsorption / desorption isotherms by suing the AUTOSORB 1C apparatus.
• Determinations types:
• Physical: adsorption / desorption isotherms, BET specific area surfaces, Langmuir, BJH pore size
distribution, total pore volume, specific surface distribution of mesopores and micropores.
• Chemical: absorption isotherms, monolayer coverage (Vm), an active metal surface, the crystallite size,
heat of adsorption, depending on the temperature reduction (TPR) with temperature desorption (TPD),
the oxidation temperature (TPO).
