In this study, a time-dependent corrosion depth estimation method using atmospheric corrosion monitor (ACM) sensor data to evaluate time-dependent corrosion behaviors is proposed. For the time-dependent corrosion depth estimation of uncoated carbon steel and weathering steel, acceleration corrosion tests were conducted in salt-spray corrosion environments and evaluated with a corrosion damage estimation method using ACM sensing data and corrosion loss data of the tested steel specimens. To estimate the time-dependent corrosion depth using corrosion current by an ACM sensor, the relationship between the mean corrosion depth calculated from the weight loss method and the corrosion current was evaluated. The mean corrosion depth was estimated by calculating the corrosion current and evaluating the relationship between the mean corrosion depth and corrosion current during the expected period. From the test and estimation results, the corrosion current demonstrated a good linear correlation with the mean corrosion depth of carbon steel and weathering. The calculated mean corrosion depth is nearly the same as that of the tested specimen, which can be well used to estimate corrosion rate for the uncoated carbon steel and weathering steel.

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.

In high-altitude corrosive environments, weathering steel is widely applied due to its excellent corrosion resistance. However, the welded joint regions, where the chemical composition and microstructure undergo changes, are susceptible to the corrosion-induced degradation of mechanical properties. This study investigates the corrosion-mechanical synergistic degradation behavior of a 16 mm thick Q500 qENH base metal and its V-type and Y-type welded joint specimens.

This work incorporates precorrosion conditioning and conductive deposits (FeS or FeS) to explore corrosion mechanisms across base metal (BM), weld metal (WM), and heat-affected zone (HAZ) regions under simulated sour conditions (NaCl (3.5 wt %), NaSO (1000 ppm), CHCOOH (100 ppm), CO, 60 °C, pH ∼ 4, and 1000 rpm). Electrochemical studies demonstrated various corrosion rates (CR) hierarchies (CS-BM (0.

This study investigated the dual role of heat input (HI) and riboflavin on microbiologically influenced corrosion (MIC) of pipe joint. The results showed that localized corrosion of the base metal (BM) and weld zone (WZ) was more severe than that in the heat affected zone (HAZ), but the general corrosion of the former two regions was less severe than that in the latter. The pit depths of BM (8.

Hydrogen fuel cell bipolar plates demand surfaces with an atomically smooth morphology and stable electrochemical interfaces to minimize contact resistance and corrosion degradation. While nickel-titanium (NiTi) alloys offer inherent advantages for this role, their practical deployment is hindered by persistent surface defects (e.g.
