Abrasion

What It Is

Abrasion is the erosion of material from a solid surface by the action of another solid. When material is removed by contact with hard particles, abrasive wear occurs. The particles may be present at the surface of a second material or may exist as loose particles between two surfaces.

Abrasive materials are used across a variety of industries for polishing, grinding, honing and other similar processes. The efficacy of these materials relies on their frictional properties, which can be calculated as the force needed to draw the material across a surface. Assessment of these properties allows manufacturers to evaluate the suitability of their products for specific uses. Test results also highlight differences between grades or brands of abrasive materials.

How To Measure It

The Abrasion Test Rig analyses the frictional properties of a wide range of materials such as sandpaper, dental abrasive strips and flexible nail files.

This enables manufacturers to highlight strengths, weaknesses and variations in product lines and materials.

Prior to performing the test, a sample of the abrasive material is held in place in a self-tightening grip.

As the test is carried out, the arm of the texture analyser draws the sample under and around a cylinder at 90 degrees and the force required to pull the material is recorded.

A software macro is then employed to analyse the multi-peak force profiles obtained and apply special calculations to evaluate the frictional properties of the material and therefore allow manufacturers to evaluate the suitability of their products for a specific use.
