Correlation between the Developed Tribofilm in Dry Automotive Clutch Field Applications with those Reproduced at Laboratory by Using a Pinon- Disc Tribometer for Three Different Severity Conditions

Fernandesa GP, Zanottoa PS and Sinatorab A

In this work the tribofilm development mechanisms in three severity levels on the field application were correlated with those simulated in a pin-on-disc tribometer. It was found that the tribofilm characteristics depend on the severity of application. In addition, the pin-on-disc tribometer can reproduce the same mechanisms that were identified on the field, due to the parity between the tribosystem characteristics of test model and field condition.
