The residual stresses of the first kind, which are formed by vibration-centrifugal hardening, are calculated. These are shown to increase in the hardened layer with increasing processing time and the weight of the hardening tool. The residual compres

The adsorption of peroxides on dispersed oxides Fe2O3, Cr2O3 and V2O5 was studied. It is shown that the adsorption of peroxides is described by the Langmuir equation. The adsorption of benzoyl peroxide grows within Fe2O3

Monomolecular films of diacyl diperoxides at the water–air phase interface have been studied. Their behaviour is influenced by the structure of the molecule and the solvent. The numerical values of the areas of molecules that are extrapolated to ze

Oligomeric peroxide adsorption of sebacic acid on aerosil and magnesium oxide was studied. Adsorption process parameters were found. It is shown that the adsorption takes place through the hydrogen bonds formation between OH– groups of adsorbents s
