Functions & Measurement Routines
The Triboster TSf-503 system provides advanced automation for physical contact interactions, allowing researchers to isolate distinct tribological variables. By integrating programmable stage motion with automated vertical probe actuation, users can execute highly precise, multi-point, time-dependent evaluation cycles that capture subtle surface variations without human error or mechanical cross-contamination.

Automatic Lift-up Function
When assessing a surface with a single directional stroke, the standard reciprocating motion drags the probe backward along the freshly worn path. This return stroke can distort measurements by altering the surface morphology or transferring loose debris. Kyowa’s Automatic Lift-up function gives customers the option to have the contact probe lifted at the completion of a forward stroke, allowing the stage to return to its zero-point completely unhindered. This guarantees that repetitive testing cycles always evaluate fresh or consistently prepared surface regions in a unidirectional path.
Continuous Static Friction
Frictional values are highly localized and often fluctuate due to subtle microscopic surface variations within a single material plane. Instead of measuring a single static friction data point at the onset of motion, this advanced routine uses a precise "stop-and-go" motion profile. The stage repeatedly steps forward and pauses, capturing up to 50 individual coefficients of static friction (μs ) along a single continuous path. This enables engineers to calculate true statistical deviations and identify microscopic variations or inconsistencies across the surface matrix.
Time-interval Dependency
The longer two surfaces remain in stationary contact under a vertical load, the more their micro-asperities (microscopic surface peaks) interlock, enabling localized adhesion and molecular bonding. This routine analyzes these chemical and physical properties by varying the stationary "dwell time" across up to four distinct intervals within a single stroke. By combining the automated counterpart lift-up system with targeted stop-and-go delay states, the TSf-503 directly evaluates how resting contact times amplify initial static friction forces, providing vital data for sticky components, rubber seals, and specialized coatings.
