Abstract
An abrasion test has been developed and used to compare the resistance to abrasion of a range of plastics and metals. The test is primarily intended for use in agricultural engineering and has been designed to cover a wide range of conditions such as occur in this industry. One of the main features of the test where it differs from most others is that it uses loose, and not bonded, abrasives. The results obtained so far, on about fifty plastics and metals, emphasize the importance of the resilience of the material in reducing abrasive wear. They also show that the resilience, or, more specifically, the vibration characteristics, of the support for the specimen, can. affect the rate of abrasion.
Plastics test specimens appear to wear into two distinct final shapes and this shape seems to depend on both the material and the test conditions; it could possibly result from the two forms of abrasive wear already described in the literature. The possibilities of further work are discussed.
