Experimentally are confirmed, what the thermal cycling are increasing the diffusion movability of impurity and alloying element , energy barrier of oxide- and nitride-formation are lowering, as a result is accelerated formation of functional stratums, the level of material defects (the instability factor) in morphological features of their structure are playing the deciding role . The generalized model of oxides synthesis process on metals in water electrolyte solutions under influence of external electrical field is offered. These model allows to establish optimal parameters of synthesis and composition of electrolytes for deriving coverages with preset characteristics. The morphology and optimal parameters of near-surface stratums on titanium alloys for corrosion and wear resistant protection is defined Product Description popup.authors popup.nrat_date 2020-04-03 Close
