Special Study Group on Corrosion and Lifetime of Materials
Purpose
The key to saving resources and energy, as well as to realize a sustainable and carbon-neutral society, is how to extend the durability and lifetime of various materials, devices, and structures that use them. Corrosion, in particular, is a cause of significant reduction in durability and lifetime, and can occur not only in metallic materials but also in ceramic and polymer materials. However, since corrosion is an environment-dependent phenomenon, counter measures are taken depending on the situation, and the knowledge and techniques obtained are often not shared. On the other hand, it is possible to find new value in corrosion products such as rust and materials that have reached the end of their useful life, and to develop synthesis and destruction processes that mimic corrosion reactions. Given this background, this special research group will hold meetings about four times a year as a networking forum for sharing and learning from a wide range of technological and academic knowledge related to “corrosion and lifetime of materials”. In addition, explanations on corrosion phenomena, corrosion prevention techniques, measurement methods, etc. are planned to be sent out on an irregular basis.

Building a Fast Degradation Prediction Model for Corrosion Prevention
By combining multiphysics simulation and machine learning, corrosion behavior over decades or centuries can be predicted at high speed, and corrosion protection designs can be optimized in ways that were previously difficult. For example, the effects of corrosion on various types of structures such as offshore wind turbines, subsea oil platforms, onshore pipelines, plants, and storage tanks can be predicted.

Utilization of Machine Learning to Integrate Corrosion Simulation and Measured Data
Actual corrosion processes progress over long periods of time and are difficult to model for simulation due to uncertain conditions. By linking with machine learning, it is possible to inverse analyze characteristic values that are difficult to observe from experimental data and actual measurements. Furthermore, using information collected by IoT, it can be expected to operate as a digital twin. (Courtesy of Keisoku Engineering System Co.)
Underwater Beam of Giboshi Bridge in Tottori Castle Ruins
It was thought to be impossible to restore the Giboshi bridge at the front gate of Tottori Castle Ruins in its original form due to the need to preserve the remains of the bridge piers at the bottom of the moat, but a new idea of placing a wooden bridge on top of stainless steel underwater beams made it possible to restore it. This state-of-the-art technology hidden underwater has been highly evaluated both domestically and internationally. (Courtesy of Nippon Steel Stainless Steel Co.)
New Nation Stadium
The design theme of the new National Stadium is the pursuit of sustainability, and one of its features is to use natural winds to control the rising temperature instead of relying on air conditioning. The roof is made of pre-coated, resource-saving stainless steel, and is coated with a fluorinated whitening coating, one of the best in its class, to suppress the rise in temperature of the roof surface due to solar radiation.

Marina Bay Pedestrian Bridge, Singapore, 2009
It is a pedestrian bridge with a radical design that resembles a DNA double-helix structure, built over Marina Bay, one of Singapore’s most famous tourist attractions, and leads to the Sands Hotel. All of its components are made of highly corrosion-resistant duplex stainless steel, and even after 14 years of construction, no corrosion has been observed.
