Test Principle

The Ring-on-Block tester drives the friction ring to rotate against a fixed test block under a set load, forming stable sliding friction. During testing, sensors continuously collect friction force signals to calculate the friction coefficient. Based on load, time, and friction conditions, material wear behavior is evaluated. Comparative testing under identical conditions allows objective assessment of material or coating wear resistance.
