Electrochemical corrosion and bacterial adhesion of local osteosynthetic maxillofacial bone plates matched the quality of an international brand.
Plenary sessions report on recent progress in electrochemical methods and in standards for
electrochemical corrosion testing.
[11] conducted
electrochemical corrosion monitoring under cyclic wet-dry conditions.
It is known that, in an
electrochemical corrosion process, the cathodic reaction activates the [O.sub.2] reduction reaction causing an increase of the pH in the cathodic sites of the metallic surface [4].
SVET measurements were carried out in
electrochemical corrosion testing apparatus at room temperature in 3.5wt% NaCl solution [19-21].
The mechanical and physical properties include the following (compressive and tensile strength, creep, dimensional change and thermal conductivity) and the corrosion properties include chemical corrosion (tarnish), and
electrochemical corrosion [3].
And the
electrochemical corrosion kinetic parameters, such as corrosion potential (Ecorr), cathodic and anodic Tafel slopes (ba, bc) and corrosion current density Icorr obtained by extrapolation of the Tafel lines are shown in Table 2.
Electrochemical corrosion testing provides fast information about the degradation of the coatings and the ongoing corrosion events without any visible corrosion induced damages.
According to Nail Ibragimov implementation of the ecological safety program in 2015 provided for installation of cathodic protection at 1,007 wells, while the
electrochemical corrosion protection systems to ensure protection against the groundwater corrosion were provided for 465 km of pipelines of the oil gathering systems; there were 849 km of corrosion-resistant pipes manufactured; there were about 5500 tons of inhibitors used for protection against internal corrosion with anti-corrosion coatings and cathodic protection provided for the inner surface of 195 tanks.
This indicates that water, oxygen, and corrosive ions diffused into the coating/metal interface and the
electrochemical corrosion reactions initiated beneath the coating.
Furthermore the
electrochemical corrosion behavior of substrate, TNTA and Zn-TNTA specimens were investigated using potentiodynamic polarization studies.
The obtained results show that the
electrochemical corrosion account is possible at application of high-tensile steels, which used in dynamically loaded constructions in corrosion environments.
