More about
The fast-reciprocating drive delivers high-performance, versatile testing for applications such as pin/ball-on-disk, plate or ring, and piston ring–liner studies. Furthermore, mounted on the XY stage via a fast-exchange adapter, it enables seamless setup and maximum efficiency.
The reciprocating drive and XY stage can additionally be operated simultaneously with independent programming for unmatched flexibility. Stroke length is furthermore easily adjustable, and speed–distance combinations can be optimized to match exact test requirements.
As a core module, it consequently serves as the foundation for multiple environmental configurations, expanding testing capabilities. Samples can moreover be quickly mounted using the universal plate holder or a range of application-specific fixtures, therefore ensuring adaptability to unique needs.
What is Linear Friction Tribometer?
An upper sample — typically a ball, pin, or cylinder — presses against the oscillating plate. The system furthermore measures coefficient of friction (COF), friction force, wear rate, wear volume, temperature, and several other tribology parameters. As a result, the ball/pin-on-plate tribometer setup is consequently ideal for characterizing tribological properties of alloys, ceramics, polymers, metals, coatings, and solid lubricants.
Rtec Solution
Our linear sliding wear tribometer module mounts directly on our tribometers. It furthermore works across a wide speed, load, temperature, and environmental range. Using various sensors, it additionally measures friction, wear, and adhesion of any reciprocating test setup with ease. The patented in-line 3D profilometer consequently measures topography change automatically during the test. Moreover, the module accommodates several application-specific chambers, fixtures, and test setups. It is therefore compliant with several ASTM, DIN, and ISO standards, including ASTM G133.
Automatic In-line Imaging
Roughness, Wear, Volume vs. Time
Correlate friction, wear and topography easily.
The 3D in-line profilometer automatically measures the surface topography of the wear track. Furthermore, the module mounts on the XY stage, which conveniently moves the sample between the test and image area.
The initial 3D image acquired using the profilometer additionally accounts for machining marks, grain boundaries, orientation of the samples, and other localized features in contact surfaces. As a result, this information helps explain differences in friction, stick slip, and wear between specimens. The figure below consequently shows an aluminum sample during a 2.5-hour ball-on-plate linear reciprocating test, with images taken every 10 minutes.
Linear Wear Friction Testing Analysis
Ball On Plate Setup And Data
Setup
Materials are tested in pairs under nominally non-abrasive conditions. For the pin on plate tribology wear test, two specimens are required. One, a pin or ball that is positioned perpendicular to the other, usually a flat plate. The universal upper and lower sample holders are used to mount the samples.
Results
Figure shows the comparison of two different test samples tested at 200°C under similar conditions of load (200 N) and frequency against a 10 mm Cr6 ball. It is clear from the test that the Sample 2 has higher friction compared to sample 1.
