The Wear of Plastics Materials in Water and Aqueous Solutions.

Abstract

An investigation has been made of the friction and wear properties of a number of thermoplastic polymers and reinforced thermosetting resins during sliding in water against a stainless steel counterface. In general, wear rates of the thermoplastics are similar to those measured during dry slidings, but the detailed behaviour of individual polymers appears to depend on their mechanical properties. In contrast, the wear rates of reinforced thermosets in water depend strongly on the way in which the counterface is modified during sliding, and wear rates may be significantly higher or lower than in dry conditions. Wear rates of some thermoplastic polymers have also been measured in oil-in-water emulsions. The results show that even dilute emulsions (approximately 1% oil by volume) are effective boundary lubricants, and this effect is attributed to the particular way in which the counterface is modified by the formation of a boundary lubricating film.
