Original abstract
The paper studies the ecological aspects of self-organisation effects in tribosystems, containing self-lubricating composite materials IPM 304 and IPM 305 in copper matrix in atmospheric medium at different normal loads. The measurements and expression of the self-organisation show low values of the coefficients of friction and wear of the contacting materials in the tribosystems. This effect is of great importance for the environmental protection because it leads to decrease of use of energy and material resources and also to decrease in the pollution of the environment with gaseous, liquid, solid components and heat from the internal combustion engines and the industrial machines. The self-organisation effects of the tribosystems are sensible towards the combinations of the contacting materials during friction – normal load, sliding rate, presence and properties of the lubrication material. It has been found out that the friction coefficient in tribosystems of self-lubricating composite materials: IPM 304 – Steel 45 and IPM 305 – steel 45 decreases in a non-linear pattern and reached values which are typical for liquid friction – 0.05 and 0.08 respectively. These results are a proof the on micro level a slef-organisation of the tribosystems occur. For the tribo-system BrO1F1 – Steel 45 the dependence of the friction coefficient has the opposite dependence – its values increase to the range between 0.26 and 0.37 which are typical for dry friction.
