Article Abstract
The correlation between inherent corrosion resistance and biofouling was investigated for five different metallic coatings. Steel panels thermally spray-coated with either aluminium, Monel, bronze or different aluminium alloys were tested in controlled salt mist conditions and electrochemical corrosion tests and subsequently employed at sea. The biofouling of the panels was monitored at different depths (5, 10 and 15 m) at periods ranging from 5 to 12 months. The main macrofouling organisms were quantified and analysed using permutational multivariate analysis. The results indicate a significant difference in fouling pressure between depths and the geographic sites used. No statistically significant link between high corrosion resistance and lower biofouling pressure was observed, indicating that the main marine macrofoulers settled equally well on corrosion resistant and corrosion prone metallic surfaces. This work sheds light on biofouling of thermally sprayed metallic substrata and it characterizes and compares biofouling assemblages from different biogeographical regions in Europe.

Super austenitic stainless steels (SASS) face challenges like galvanic corrosion and antibacterial performance when welded to carbon steel (Q235) in marine environments. This study demonstrates that adding 1.0 wt% cerium (Ce) to SASS refines the heat-affected zone (HAZ) grain structure (from 7 μm to 2 μm), suppresses detrimental σ-phase precipitation, and forms a dense oxide film.

Localized corrosion in metallic materials is a stochastic phenomenon that causes irreversible structural failure. Its initiation, which occurs at the solid-liquid interface on the nanometer scale, remains difficult to predict and challenging to characterize. Herein, we describe an experimental platform that exploits advances in electrochemical liquid-phase scanning and transmission electron microscopy (LPSEM and LPTEM) to study pitting corrosion of thin-film pure aluminum in a saline environment in real time.

Sulfidized zero-valent iron (S-ZVI) holds promise in the remediation of chlorinated hydrocarbons. However, S-ZVI is susceptible to corrosion in aquifers with elevated dissolved oxygen (DO) levels. This study demonstrates, for the first time, that a trade-off between the passivation and oxidative corrosion of aged S-ZVI can be achieved in the presence of silicate to promote its dechlorination performance on trichloroethylene.

Metal matrix composites are widely employed in aerospace and marine engineering due to their excellent mechanical properties and chemical stability. However, their surfaces remain vulnerable to corrosion, icing, and mechanical wear, severely compromising long-term reliability in harsh environments. Inspired by natural superhydrophobic surfaces such as lotus leaves, functional interfaces with high water repellency and interfacial stability can be engineered through the synergistic design of hierarchical micro/nanostructures and low-surface-energy chemical modifications.

Titanium is widely used for dental implant abutments due to its mechanical strength, biocompatibility, and corrosion resistance; however, its gray coloration can compromise esthetic outcomes, particularly in patients with thin or translucent gingival biotypes. Anodization, a surface modification technique altering the titanium oxide layer, has been proposed to improve soft tissue aesthetics by producing abutments with warmer tones (eg, pink or gold) that harmonize with the surrounding gingiva. This systematic review aimed to evaluate the clinical and aesthetic outcomes of anodized titanium abutments compared to non-anodized titanium and other materials, with a focus on peri-implant soft tissue health and visual integration.
