Home By Test Type Dynamic wear and friction tests

Dynamic wear and friction (tribological) tests measure surface changes—such as scratches, gouges, and material loss—caused by friction between surfaces, thereby determining the coefficient of friction and wear resistance. These tests simulate real-world conditions (load, speed, temperature) for lubricants and materials, measuring friction forces and wear.

Dynamic wear and friction (tribology) tests are used in a wide range of industrial sectors, primarily to optimize performance, ensure component durability, and reduce energy losses.

The main sectors include:

Automotive and Transportation:
Testing of engine components (pistons, piston rings), braking systems, bearings, transmissions, and tires to evaluate their wear resistance and dynamic coefficient of friction.
Mechanical Engineering and Manufacturing:
Analysis of machining tools, rolling bearings, gears, and slide ways to optimize coatings and tribological performance.
Chemical and Materials Industry:
Testing of innovative materials, synthetic lubricants, and coatings to reduce wear and improve efficiency.
Biomedical:
Evaluation of wear in materials for joint prostheses (e.g., hip, knee) to ensure maximum biocompatibility and durability.
Oil & Gas and Railway:
Testing of components subject to extreme wear, vibrations, and high loads, such as valves and railway systems.

Dynamic tests for measuring wear and friction are generally performed using biaxial machines.
