Testings

Material/product testing laboratories are qualified for mechanical, metallographic and chemical testing of metals, alloys and metal products, rubber, fuel and lubricant characteristics testing, non-destructive testing of materials and specific tests. Within them, there are top opportunities for wide-range testing and certification of materials through:

Testing of chemical composition of metals using modern methods of analysis: atomic absorption spectrophotometry, infrared absorption, electron microscopy, quantometry and gas chromatography;
Determination of physical characteristics of fuels and oils; kinematic viscosity, flash point, density, corrosivity, impurity content in the liquid, determination of TAN;
Quality testing of protective (metallic, non-metallic and plasma) coatings: thickness, elasticity, hardness, adhesion, corrosion and impact resistance;
Testing the characteristics of rubber sealing material;
Determination of mechanical characteristics of materials: strength, tensile strength, hardness (all standardized methods and microhardness), toughness, testing of materials at elevated temperatures, creep tests, compression, bending;
Testing of metallographic structure and microstructure with sample preparation, microscopy and microstructure analysis
Non-destructive testing of materials and parts using X-ray flaw detection - standard and microfocus, ultrasonic flaw detection, eddy current flaw detection and penetrators;
Process and stuff certifications: attestation of welders and etc;

A significant segment of laboratories are also development testing laboratories. Their work includes testing the reliability of components, assemblies and systems by subjecting them to pre-prescribed conditions.

In this sense, we can complete:

Climatic-mechanical tests with the possibility of controlling the change of temperature, humidity, pressure, and vibration in one or pressure and vibration in one or more axes,
Measurement of the flow velocity field using Laser Doppler Anemometry (LDA) and Hot Wire Anemometry,
Low-cycle fatigue testing,
Measurement of temperature and distribution of temperature fields by the method of infrared radiation thermovision,
Measuring stresses in materials using measuring tapes,
Balancing of fan rotor, turbocharger rotor and more
