| Popis: |
Plasma electrolytic oxidation (PEO) was carried out on SLM-produced AlSi10Mg alloy using various corrosion inhibitor additives. The study investigated the effects of these additives on microstructural evolution, phase composition, and corrosion behavior by comparing the functionalized coating to a standard base silicate PEO one. The results revealed that, in most cases, the additives significantly altered the coatings' thickness, density, and adherence, leading to improved corrosion resistance due to an enhanced barrier effect over electrolyte penetration. Long-term immersion electrochemical impedance spectroscopy (EIS) tests proved the additives’ corrosion inhibitor capability, as they all were able to enhance coating stability. |
