Nanosized particles possess characteristic physical and chemical properties different from those of bulk materials due to the confinement of electrons, excitons, and photons into small volumes.
In the following measurements, 20nm and 5000nm Fe powders wrapped by the same insulating materials are measured at the same time.
Thus independent of materials wrapping Fe powders, we can compare the distinctions of heat transfer among Fe powders.

Porous materials were not considered at the point [9, 12].
In the case of non - porous bodies (impervious), e.g. sliding bearings made of monolithic material, there will not be the stages of internal diffusion (b, f) and in the case of materials with weak catalytic interaction we often cannot take into consideration adsorption and desorption stages (c, e).
In Fig.2 in chemical reaction physical effects are superimposing as a result of specific work of sliding bearing and causing the character circulation of oil in bearing interspace, a little different from oil circulation in the standard sliding bearing, where both elements (journal and bearing bush) are made of monolithic materials.
In the case of the analysis of sliding bearing such a situation may relate to the lubricating oil located in the lubricating interspace and to the bearing journal.

When compared with the traditional materials, the advantages of composite materials are high strength, stiffness, lightweight, heat resistance, moisture resistance, chemical and corrosion resistance to aggressive environments, low thermal conductivity, and design flexibility.
The problem of monitoring the condition of composite material has become relevant to the development and widely used of composite materials.
