Laboratory
1. Chemistry laboratory
Evaluation of chemical composition of used materials is carried out spectometrically and is consequently chemically analysed.
Equipment used:
Optical emission spectrometer Hilger E983C
Analyser C and S – Leco CS225
Additionally, analysis of selected input basic materials and ferroalloys is carried out.
2. Mechanical testing
Testing mechanical properties:
standard temperature tensile test (longitudinal test piece of circular cross section with smooth ends, flat longitudinal test piece (sheets, springs), estimation of Rm, Re,Rp0,2, A5, Z.
guided bend test
impact bend test at standard temperature, at lowered temperature ( +40°C to -60°C)
notched impact test - KV, KCV, KU, KCU
Brinell, Vickers, Rockwell hardness tests. (HB, HV, HRC)
Equipment used:
Tensile testing machines EDZ
Tensile testing machines ZD40
Tensile testing machinesZD10
extensometer MKe
impact machine PS-30
hardness tester HPO 250
hardness tester HPO 300
hardness tester Rockwell.
Test specimens for all laboratories are prepared in a single-test mechanical workshop. This workshop prepares all kinds of materials apart from extremely hard ones.
3. Metallographic laboratory
Evaluation of material metallographic structure:
evaluation of microstructure after heat-treatment precision test
evaluation of material micro-fineness
evaluation of grain size
evaluation of cast iron
evaluation of decarburisation
evaluation of surface hardened and cemented case
quantitative analysis
evaluation of defects and breakdowns of machinery parts
Special expertise for assessment of causes of defects and breakdowns of machinery parts.
Equipment used:
light microscope Neophot 2
light microscope Neophot 32, accessory equipment - microhardness tester
4. Sand laboratory
Observation, control and evaluation of quality of sand mixtures using operational apparatus in sand laboratories.
Equipment used:
type: PED – equipment for measuring permeability
type: PFG, LRU – equipment for measuring pressure and shearing strength
