Abstract

Summary: Single‐asperity wear measurements were performed on small quantities of polyethylene with different molecular weights. Experiments could be performed on a surface area of 25 × 3000 μm^2^. A quantitative value of wear rate could be obtained that was proportional to macroscopic results relating the wear rate to the molecular weight. Material transfer limited the maximum sliding velocity to 1 μm · s^−1^. Possible solutions for this problem have been identified and will be a subject of further investigation.
