Modeling of worn surface topography formed in a low wear process

Two batches of experiments are described in this paper. The first tests were conducted on a reciprocating tester. Specimens were cut from cylinder liners from gray cast iron of hardness 2128 MPa after honing or plateau honing. They co-acted with counter-specimens made from chromium-coated steel C45. Lubricating fluid was supplied to the contact zone. The second tests were carried out on a block-on ring tester. Stationary block prepared from cast iron with a hardness value of 5356 MPa was ground. Rotating rings made from steel of 2992 MPa hardness were modified by a burnishing technique to obtain surfaces with dimples. The tested sliding pair was lubricated. The abrasive wear resistance tests were conducted under artificially increased dustiness conditions.
