Regularities of change of water-repellent properties of the nanostructured metal powders on the base of aluminium

Article preview

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.

On the interrelation of water repellent properties and reactivity during oxidation of nanostructured metals based on steel and aluminum

Article preview

It was examined the correlation between water-repellent properties and reactionary properties in the process of oxidation for nanostructured materials, based on steel and industry trademarks of aluminum powder. Analysis experimental data showed, that for samples, which have nanofilms on cationic tensides and silicon-organic compounds on steel there is the symbatic correlation between water-repellent properties of coatings and their protective properties. And samples, based on aluminum, have highest intensivity of oxidation with middle level of water-repellent properties.

Optimization of shock fracture of materials with cracks

Article preview

The problem of optimization of impulse fracture of materials with a crack is investigated. Expressions of threshold characteristics of shock loading are obtained. The influence of the crack length on the value and duration of the minimum fracture pulse is investigated.

On the dependence of dynamic fracture toughness on the size of a crack in a material

Article preview

The problem of dynamic loading of a material with a crack is investigated. Expressions for dynamic fracture toughness using the incubation-time criterion are obtained. It is shown that the graphs of dependence of dynamic fracture toughness on time to fracture qualitatively change with the crack length.
