Charakterystyki zużyciowe łożysk ślizgowych z czopem z powierzchniową warstwą dwuskładnikową.

In the paper there are presented test results of model sliding bearings tribological wear with pin made with two-component surface layer steel 34HNM-copper lubricated by clean oil and with aluminium oxide impurities. The reference level was wear of bearing element with pin of steel 34HNM. Bearing bushes were made of MB50 alloy, the pin with two-component surface layer was also tested in cooperation with steel 45. In the case of polluted oil lubrication the wear of pin with two-component surface layer was three times lower than wear of the pin of steel 34 HNM. Anyway the wear of pin modified by cooper cooperating with the bush of steel 34 HNM cooperating with bush of MB50 alloy.
