Friction Testing System
Term:Friction Testing System
Category: Equipment
Definition: A friction testing system is an analytical device used to evaluate the frictional characteristics of coated or uncoated materials. For hydrophilic coatings, the system is designed to determine the ease at which one surface slides over another surface under known controlled conditions. This observation indicates the lubricity and wear resistance of the coating. The experimental data allows for evaluation of the performance, consistency of performance, and degradation of the coating after exposure to moisture, sterilization, or repeated use.
How it Works:
- A sample (e.g., coated catheter or test strip) is mounted on a movable stage or test fixture.
- A probe or counter-surface (often a stainless-steel plate or simulated tissue surface) is pressed against it with a known force.
- The stage moves at a controlled speed, and the frictional force is continuously measured.
- Software calculates the static and dynamic coefficients of friction (COF) from the recorded data.
- Tests may be performed in dry or wet (hydrated) conditions to mimic real application environments.
