TRANSPORT PROPERTIES OF COATINGS CONSISTING OF Al2O3 NANOPARTICLES

The technology of obtaining coatings consisting of alumina nanoparticles and their agglomerates is presented. The transport properties of coatings and the change of these properties with time are investigated. The dependence of the height of capillary ascent on the quantity of deposited nanofl uid on substrates has been established. An estimate of the change in the height of liquid rise and of the permeability of a coating with the change in the size of particles has been made. Deterioration of the transport properties of porous coatings consisting of alumina nanoparticles with time is investigated, and the possibility of restoring these properties is shown.
