Considering the concept of synergism in corrosion inhibition
Anton Kokalj
Izvirni znanstveni članek
Oznake: corrosion inhibition;synergism;Langmuir adsorption model;
Synergism in corrosion inhibition and how to best quantify it is explored conceptually. In the equation for the synergistic parameter, the mixture’s inhibition efficiency is evaluated against a threshold inhibition efficiency based on the performance of pure compounds. However, the choice for the th ...

On the use of the Langmuir and other adsorption isotherms in corrosion inhibition
Anton Kokalj
Izvirni znanstveni članek
Oznake: Langmuir isotherm;Flory–Huggins isotherm;Temkin isotherm;corrosion inhibition;standard adsorption free energy;
In corrosion inhibition studies, the standard adsorption Gibbs energy is often estimated via the linear regression of the Langmuir isotherm in the 𝑐∕𝜃 = 1∕𝐾 + 𝑐 form, where both the intercept and the slope are estimated, although the Langmuir isotherm requires the slope of 1. Hence, 𝑐∕𝜃 = 1∕𝐾 ...

ǂA ǂgeneral-purpose adsorption isotherm for improved estimation of standard adsorption free energy
Anton Kokalj
Izvirni znanstveni članek
Oznake: standard adsorption free energy;corrosion inhibitors;adsorption isotherms;
A new general-purpose Type–I adsorption isotherm is proposed to improve standard adsorption Gibbs energy estimation. This new isotherm stems from considering a functional dependence of various adsorption models on the 𝑐∕𝜃 vs. 𝑐 plot, where 𝜃 is the fractional surface coverage and 𝑐 the concentr ...

On the estimation of standard adsorption free energy from corrosion inhibition efficiencies
Anton Kokalj
Izvirni znanstveni članek
Oznake: standard adsorption free energy;corrosion inhibition;surface coverage;adsorption isotherm;
The standard adsorption Gibbs energy (Δ𝐺−◦ ads) is often estimated by assuming that the corrosion inhibition efficiency is equivalent to fractional surface coverage. However, Lindsay et al. [Corros. Sci. 155 (2019) 182– 185] demonstrated that this assumption is not necessarily valid. Therefore, a m ...

Optimizacija procesov v servisni dejavnosti gospodinjskih aparatov
Anton Kokalj, Davorin Kofjač
Diplomsko delo
Oznake: servis;organizacija;prenova;
V podjetju Gorenje so pred približno desetimi leti projektirali sodoben servis s hitro odzivnostjo. Za stranko je to pomenilo eno najboljših servisnih strežb na področju gospodinjskih aparatov. Podjetje si je pridobilo pomembno prednost pred konkurenco in prodaja je sčasoma začela naraščati. Za serv ...

Atypical adsorption of hydrogen on native ultrathin aluminum oxide films
Matic Poberžnik, Anton Kokalj
Izvirni znanstveni članek
Oznake: hidrid;ultra tenki filmi;vodik;
We report on an unusual hydrogen adsorption mode on native ultrathin aluminum-oxide films. Based on systematic density-functional theory (DFT) calculations on a model oxide film of varying thickness—i.e., α–Al2O3(001) supported on Al(111)—we show that on ultrathin films, H preferentially adsorbs on ...
