Ball-on-Disk Tribometer




Anton Paar Ball-on-Disk Tribometer 

Model

TRB³


Measuring range

1. Positive load:1 ~ 60 N

2. Friction range: up to 20 N

3. Rotation speed: 0.2 rpm ~ 600 rpm

4. Rotation radius: up to 40 mm


Measurement items
Sample friction coefficient and abrasion rate



Use the Ball-on-Disk abrasion tester to test samples wear resistance and friction coefficient to evaluate the film mechanical properties. It uses specific positive force load and speed, and sets the speed, grinding track length and grinding track diameter to form a channel with a specific radius and abrasion length on the material. Measurements of the depth and width of the abrasion are used with a formula to evaluate the abrasion rate (WR) of the film.
