Abrasive Wear Testing

The removal of material from a surface by harder material impinging on or moving along the surface under load is termed abrasive wear. The hard material indents the surface and depending on the properties of the materials and the type of motion or loading, may remove material by various mechanisms, e.g. cutting, ploughing, chipping or fatigue cracking.

 

The TE66 micro scale abrasive wear test rig
The TE 66 may is often used to determine the wear coefficient of hard and soft coatings and monolithic materials by abrasive wear in a ball on plate contact configuration in the presence of an abrasive slurry.
The TE66 can be used for coating thickness determination
The machine is also used as a crater-generating tool on coated surfaces for coating thickness determination.
The TE 66 complies with test requirements in accordance with BS EN 1071-6: 2007
The TE 66 complies with test requirements in accordance with BS EN 1071-6: 2007. Typical ball rotation speed is 1 – 150 rpm and applied load rages from 0.01 – 1 N.
The rig can also be used to perform tribocorrosion experiments under electrochemical control
The rig can also be used to perform tribocorrosion experiments under electrochemical control, by the incorporation of a three-electrode setup with an insulating (ceramic) ball and temperature controlled bath to contain the electrolyte of interest.

In the study of abrasive wear, distinction is often made between two-body and three-body abrasive wear. The former is caused by hard asperities penetrating into the counterface, while in the latter case, free particles are trapped in-between the sliding surfaces and can roll, slide or even abrade each other. Various apparatus are currently used to assess the abrasive wear of materials; they include Taber abrasion test rig, dry sand/rubber wheel abrasion tester and micro scale abrasive wear tester. Out of the three, the micro scale abrasive wear tester is the most reliable and versatile.
