摘要：At present ecological requirements are in the greatimportance. A lot of studies had been made in the field ofbio fuels, trying to reduce pollution by exhausted gases anduse renewable resources [1, 2]. At the same time tribologi-cal properties ate important too. Friction and wear in themachine elements consumes a great part of the energy re-quired. Various surface treatment technologies and specificlubricants are suggested [3, 4]. Nevertheless from the eco-logical point of view rapeseed oil is remaining as mostattractive basis for the production of environmentallyfriendly lubricants. This attractiveness is caused by biode-gradable properties together with comparably good lubri-cating characteristics [5].
