Abstract

Regularities of change of water-repellent properties of metal powders on the basis of aluminium depending on the program of nano-structural surface modifying are studyed. The rows of increase of water-repellent properties of modified aluminium on the base of coarse-dispersed and high-dispersed (PAP-2) powders are obtained. Several specimens excelling initial hydrohobic PAP-2 inits water-repellent capacity are found out. The research uses the methods of XP-, EDX- spectroscopy and gravimetry.
