High-Pressure Friction and Wear Tester
High-Pressure Friction and Wear Tester is a temperature-controlled tribological testing system designed to evaluate friction and wear behavior of gases, lubricants, and materials under high-pressure conditions. The tester provides a rigid, sealed pressure chamber and a wide load range, enabling controlled ball-on-disk and pin-on-disk tests that simulate real high-pressure tribological environments. It is suitable for studying friction mechanisms, wear characteristics, and material interactions where pressure and gas environment play a critical role.

FAQ
1. What types of tests can be performed using the High-Pressure Friction and Wear Tester?
The tester is designed to perform tribological tests under high-pressure conditions, including ball-on-disk and pin-on-disk configurations. It supports friction and wear measurements of gases, lubricants, and solid materials in a sealed, pressure-controlled environment. This makes it suitable for evaluating valves, seals, bearings, compressors, coatings, and other components whose tribological behavior is influenced by pressure and gas environment.
2. Why is pressure control important in high-pressure tribological testing?
In high-pressure applications, friction and wear behavior are strongly affected by the surrounding gas environment and pressure level. Chemical reactions, dissolution rates, and surface interactions at the contact interface can change significantly under pressure. The tester provides programmable, real-time pressure control using a capacitive pressure sensor, allowing these effects to be studied under controlled and repeatable conditions that closely simulate real operating environments.
3. What load and temperature ranges are supported by the tester?
The High-Pressure Friction and Wear Tester supports a wide load range from 5 N to 2000 N, enabling simulation of various high-pressure contact conditions. The temperature control system covers a range from −35 °C to 100 °C, allowing evaluation of tribological behavior across different thermal environments while maintaining pressure stability.
4. How does the system ensure reliable and repeatable test results?
The tester uses a rigid chamber structure, real-time load control, and capacitive sensors to measure pressure, friction force, wear depth, and temperature during testing. These design features, combined with controlled test environments, provide high reliability and repeatability, making the system suitable for both research studies and comparative material evaluation.
