Abrasion rotative Testeur - Applications:

La Testeur d'abrasion à plate-forme rotative, commonly known as the Rotary Abraser ou Rotary Abrader is a seminal instrument in material science and engineering for quantitatively assessing the resistance of surfaces to wear. Its principle provides an accelerated, standardized method to simulate long-term abrasive forces, yielding reliable data within minutes, a stark contrast to the extensive duration often required for in-situ field testing.

Test Method:

The core mechanism involves mounting a flat, circular or square specimen, typically 100mm in size with a central hole and up to 6.35mm thickness, though accessories allow for thicker materials, onto a rotating turntable. This turntable revolves on a vertical axis at a fixed, controlled speed of usually 60 or 72 revolutions per minute. Two specialized Roues abrasives are then precisely lowered onto the specimen's surface, applying a specified standard Test Loads of 250g, 500g and 1000g, optional auxilliary weights are available.

Ces Roues abrasives are driven by the rotating specimen itself, but crucially, they are mounted on horizontal axes that are tangentially displaced from the specimen's central axis. This unique configuration induces a characteristic "rub-wear" action: one wheel abrades the specimen outwards towards its periphery, while the other abrades inwards towards the center. The resulting abrasion pattern forms a series of crossed arcs within a circular band with a size of approximately 30 cm², ensuring that the material's abrasion resistance is evaluated across all angles relative to its weave, grain or orientation. A vacuum system is continuously engaged during the test to remove loose wear debris, preventing a 'three-body' abrasion effect that could skew results.

A critical feature of the Single Head Abraser is the use of reliable Meules abrasives available in various grades with silicon carbide or aluminum oxide abrasives embedded in resilient or vitrified binders. These proprietary wheels are engineered to ensure continuous exposure of fresh abrasive particles as the binder material breaks down during use, maintaining consistent abrasive action throughout your sample tess.
