Charge transfer at the antiscale composite layer-electrolyte interface

Properties of composite coatings based on oxide layers formed on a titanium surface using the plasmic electrolytic oxidation method and processed using Forum? superdispersed polytetrafluorinethylene were investigated. A combination of electrochemical impedance spectroscopy, differential thermal analysis, and thermal gravimetry methods allowed one to establish the change of the surface state as a result of heating that determines the charge transfer mechanism at the heterostructure-electrolyte phase interface and the difference in the thermodynamic stability of the temperature fractions of the employed polymer.

Models for dynamic conditions in granulation

Models are derived for the dynamic conditions in granulation in an apparatus in which the suspension is fed into the jet.     

Calibration characteristics of static-pressures (efforts) piezoelectric transducers

Conclusions The piezoelectric transducers under consideration can be used for measuring static pressures. They can be provided with either an inverse or forward calibration characteristic, and this is of considerable practical interest for matching these transducers to secondary measuring instruments.Translated from Izmeritel'naya Tekhnika, No. 4, pp. 86–87, April, 1973.
