Technique for the Determination of the Critical Points under Acoustic Emission Tribological Tests

Аннотация

The use of the acoustic emission technique for the determination of the critical points under tribological tests using standard friction machines is shown by citing a specific example. The distinctive feature of the proposed approach is the use of special techniques for the determination and presetting of the fracture load and the simulation of the predominant wear processes in a friction pair. This approach can also be used as a technique for the identification of the AE sources registered under the friction and wear of different friction units. It was shown that confocal laser microscopy can efficiently replace most of the well-known wear evaluation techniques.
