Theoretical and experimental approach of friction in a multi-samples sand-slurry tribotester

Abstract

The „sand-slurry” method is wellknown among the abrasive tribotesting procedures[1-5]. Based on the DIN50322 standard defining the different tribotesting categories the number VI.category suggests the application of simplified test samples and conditions under control. At theInstitute for Mechanical Engineering Technology a new sand-slurry tribotester was developed featuredby the multi-samples holders taking different speed and load condition into account within one testrush. The resulted friction loss of the tests can be calculated by torque measurements andapproaching calculation as well. The testrig and the method is used for testing different coated steelsamples.
