Undergraduate Project: Micro-abrasion mapping of steel/polymer couples in aqueous conditions.

There has been increasing interest in the mechanisms of micro-abrasion of materials, due to widespread occurance of wear by micron sized particles in bio-medical applications such as in Dentistry and in wear of total replacement hip joints. The purpose of this project to investigate the micro-abrasion behaviour of a range of material couples using the PLINT TE 66 micro-abrasion apparatus. The variables considered in the work tested include rotation speed and applied load and the materials tested include steels and polymer based materials. The results are being used to construct micro-abrasion maps for the micro-abrasion interaction.
