Tribological research and development

Tribological research and development Bay Zoltán Kutatóközpont

One of the main profiles of the Engineering Division of the Bay Zoltán Research Institute is the investigation of tribological processes, including lubricant properties, friction, wear, surface fatigue and service life, on the contact surfaces of machine components and drive train components.

The Division's staff have in-depth knowledge, combined with numerical simulation capabilities, to enable complex research and development of a complete tribo system.

Services

Tribological testing of drivetrain elements/components

Laboratory wear testing of metal, ceramic and plastic contact surfaces for alternating, rotating and arbitrary paths according to real kinetics

Lubricant performance testing, grease and oil EP and wear protection testing

Investigation of the fatigue process of sliding-rolling RCF on contact surfaces, investigation of the galling process, service life test

Investigation of stick-slip phenomenon with ball-on-disc assembly to determine the appearance of nuisance acoustic emissions

To establish a validated modelling procedure for the calculation of the failure process of sliding-rolling contact surfaces, including the relevant parts of the manufacturing process.

Analysis and characterisation of lubricant properties (FTIR, GD-OES, Gas chromatography, TAN acid number, viscosity, density, SEM particle analysis)

Sliding wear resistance test with block-on ring assembly

Lubricant film test, with contact electrical resistance measurement

Investigation of frictional conditions, recording of Stribeck curve with temperature measurement

Tribological testing of plain, ball and roller bearings

Numerical simulation of tribological processes, where we can extract additional information for the development of surface coatings and surface treatments that cannot be obtained by measurement.

Brake bench driveline testing for trucks and agricultural vehicles
