Arnold, JC and Hutchings, IM (1989) Mechanisms of erosion of unfilled elastomers by solid particle impact. Wear of Materials: International Conference on Wear of Materials. pp. 99-107. ISSN 0192-4990Full text not available from this repository.
The mechanisms of material removal were studied during the erosion of two unfilled elastomers (natural rubber and epoxidised natural rubber). The effects of impact velocity and of lubrication by silicone oil were investigated. The development of surface features due to single impacts and during the early stages of erosion was followed by scanning electron microscopy. The basic material removal mechanism at impact angles of both 30° and 90° involves the formation and growth of fine fatigue cracks under the tensile surface stresses caused by impact. No damage was observed after single impacts; it was found that many successive impacts are necessary for material removal. It was found that the erosion rate has a very strong dependance on impact velocity above about 50 ms-1.
