The life of a concrete bridge exposed to deicing salt or seawater has often been limited by corrosion of the steel reinforcement. The service life of a concrete structure, degraded by corrosion, is considered to be the sum of the initiation and propagation periods. The initiation phase is the time required for sufficient accumulation of aggressive species at the rebar surface to initiate corros...

Corrosion of mooring chains is regarded as one main threats to the offshore systems. Localized corrosion even more dangerous than uniform because it may not show significant mass loss but can cause stress concentration and initiate cracks under force, leading accelerated degradation chains. steel in seawater influenced by many factors such local heterogeneities steel, electrochemical microbiolo...

Seawater splitting powered by solar or wind sources is a significant renewable energy storage technology for the production of green hydrogen energy. However, both chlorine evolution reaction and chloride corrosion are intractable issues in seawater splitting. Here, porous electrode based on phosphate-intercalated NiFe (oxy)hydroxide shell coated nickel molybdate (NiMoO4) micropillar core (deno...

Abstract The problem of insulation voltage selection in potential-difference detection method performance electrical insulating metal pair flowing seawater is discussed. In seawater, 921A-B10 was taken as the research object to design corrosion test material. natural test, galvanic and simulated material were carried out respectively. shows that larger analog resistance series is, smaller curre...

Ships are a means of transportation over the sea, where ships play vital role in socio-economic aspect through their distribution function between regions. One part ship that is often damaged hull ship. The cause damage corrosion. high and low level corrosion on salinity content seawater. This study aims to determine effect seawater rate plate with media taken from waters port Tanjung Emas Sema...
