The Application of CRN Coating in Sliding Pairs under Lubrication Conditions
MetadataShow full item record
This work revealed the results of the impact of the formed surface layer CrN and the surfaces layer CrN-steel 46Cr2 “ring” structure. The sliding pairs worked under conditions of lubricating the friction area with Lotos Syntetyk 5W/40 engine oil. In the sliding pairs, the counter-samples were made of CuPb30 and AlSn20 bearing alloys. The results of the tests proved the possibility of implementing “ring” structure in sliding pairs, which work under mixed friction conditions. The test revealed that the moment of friction at the start-up, the friction force, the temperature in the friction area contact and the wear of the bearing material depend on friction conditions and a combination of the cooperation surface layers of sliding pairs.
