Physical Model for Electrochemical Oxidation of Composite Ceramics
The paper examines the corrosion behavior of dense ZrB 2 -based ceramic samples in simulated seawater (3% NaCl solution) using polarization curves of electrochemical oxidation (ECO). The dense ceramic samples of 3–5% porosity were produced by hot pressing and had the following composition (wt.%): Zr...

-based ceramic samples in simulated seawater (3% NaCl solution) using polarization curves of electrochemical oxidation (ECO). The dense ceramic samples of 3–5% porosity were produced by hot pressing and had the following composition (wt.%): ZrB
2
, 77 ZrB

–23 SiC, 70 ZrB
2
–20 SiC–10 AlN, and 60 ZrB
2
–20 SiC– 20 (Al

). The main ECO parameters were the conduction current
i
, corrosion current
i
corr
(
i
value at which d
i
/d
E
decreased through diversion of some oxygen ions to oxidize the material), and anode potential
E
a
(
E
value at which the protective oxide film failed (
i
> 0)). A two-stage model of the ECO process was proposed upon analysis of the experimental data. At the first stage (
E
<
E
a
,
i
= 0), an oxide film developed on the effective surface: the higher the protective function of the oxide film, the greater its thermodynamic stability. The second ECO stage (
E
>
E
a
,
i
> 0) had two steps of changing the conduction current
i
, carried by negative oxygen ions. The first step was characterized by an avalanche-like increase in
i
at
E
=
E
a
up to maximum
i
=
i
corr
, at which the rate of change in
i
decreased with increasing anode potential (d
i
/d
E
). At higher
i
corr
(second step), the increase in
i
corr
with greater
E
slowed down through the interaction of oxygen with the test material, i.e., through oxidation. The higher the maximum
i
corr
value, the greater the oxidation resistance of the material. According to the proposed model, the highest values of
E
a
and
i
corr
in ECO conditions for ZrB
2
–SiC materials are reached when AlN is added as it promotes the formation of thermodynamically stable mullite in the protective film. An Al
2
O
3
–ZrO
2
oxide addition increases the oxidation resistance of the material (high
i
corr
values) but does not change the composition of the outer borosilicate glass film. This explains the close anode potentials of the 77 ZrB

E

2
–20 SiC–20 (68 Al
