Abrasion

ABRASION is the process of eroding material from a solid surface through the action of another solid. Abrasive wear occurs when material is removed by contact with hard particles. The particles may be on the surface of the second material, or they may be loose particles between the two surfaces. Abrasive materials have uses in many industries, including polishing, grinding, honing, and other similar processes. The efficacy of the act of abrasion is reliant on the materials’ frictional properties, and can be calculated as the force required to drag the material across a specific surface. Assessing these properties allows manufacturers to evaluate the suitability of products for a specific use. Test results can also show differences between brands or grades of abrasive materials.

Typical Methods:

An Abrasive Test Rig is used to analyze the frictional properties of many materials, such as sandpaper, dental abrasive strips, and flexible nail files. This allows manufacturers to highlight strengths, weaknesses, and variations in product lines and materials, giving them quantifiable results.

First, a sample of the abrasive material is secured using a self-tightening grip. As the test is run, the arm of the TA.XTPlus or TA.HDPlus pulls the sample under and around a cylinder at 90 degrees, recording the force required to perform this action. The cylinder material is customized to the specific test.

The multi-peak force profiles are analyzed using Exponent Connect software, using special calculations to evaluate the frictional properties of the material. Coarser samples will show a wider fluctuating force band, while finer materials will record a narrower force band.

As well as providing accurate measurements of the material’s frictional properties, the recorded results can also be used to evaluate the abrasive sample’s stick/slip characteristics, by calculating the force difference between the maximum and minimum peaks obtained.

Results

The texture analyzer graph will typically show Mean Friction Force and Stick/Slip.
