Comparison of the tribological properties of the surface layers oF TiN and CrN

Lubas P.

Journal of KONES

2005

Vol. 12, No. 1-2

195-200

This work revealed the results of comparative surveys of the impact of formed surface layer TiN and CrN and two component surfaces layer TiN-steel and CrN-steel. The slide couple worked in conditions of lubricating the friction area with Lotos Syntetyk 5W/40 and Castrol GTX Magnatec 5W/40 engine oils. In the friction couple the counter sample was made from CuPb30 bearing alloy. The tribological survey was carried out on a Tester T-05. The results of the tests proved the possibility of implementing two component surface layers in slide couples, which work under mixed friction conditions. The surveys revealed that the friction force, temperature within the friction area and wear of bearing material, depend on friction conditions and combination of mating surface layers of friction couple. Beneficial friction parameters were observed in case of friction couples with binary CrN-steel surface layers of the journal.
