Abrasion of polymer surface films or coatings in an everyday occurrence, whether in the home, work or industry. As a result a wide variety of polymer films can be found on surfaces. Despite the numerous applications, three body thin film abrasion appears a niche area of study and as a result under-researched.

This investigation focuses on identifying, characterising and quantifying the abrasive wear of a baked dehydrated castor oil deposit formed on stainless steel. The primary aim of this project is to understand how the fundamental properties of the liquid abrasive cleaning system contribute to the material removal. Investigations have primarily been carried out using a reciprocating linear tribometer for the cleaning and a profilometer to measure the wear.

The wear of the baked oil film was found to largely follow the established Archard wear equation of sliding distance and load, despite the fact it was derived to describe two body and not three body wear. However the wear rate was not inversely proportional to hardness and there were significant effects when parameters not in the Archard equation are considered. IN particular changing the speed, viscosity, particle size and distribution all had an impact on the wear.
