EBARA Corporation (hereinafter referred to as "EBARA") and EBARA Environmental Plant received the 2021 Technology Award from the Japan Society for Corrosion Protection and Corrosion (hereinafter referred to as the Japan Society for Corrosion and Corrosion Protection).
Received a technical award from the Japan Society of Corrosion Protection and Corrosion
Certificate of commendation
1. Background
The Japan Society for Corrosion Protection is the only organization in Japan that aims to promote and disseminate research and technology on corrosion protection of materials in general. The Technology Award is given to technologies that have contributed widely to the development and enlightenment of technologies in the field of corrosion protection.
2-1 Overview
The details of this year's awards are as follows.
| Award-winning technology | "Development of high-temperature erosion and corrosion¹ thermal spray coatings with uneven surfaces" |
| Winners | Ebara Corporation, Technology & R&D Management Department, Manabu Noguchi Ebara Environmental Plant, Common Infrastructure Headquarters, Eiji Ishikawa |
| Evaluation points | (1) It was discovered that the uneven shape of the surface is effective in suppressing corrosion, wear, and thinning in a biomass combustion environment. (2) Development of material composition and manufacturing method in which unevenness spontaneously manifests (3) Commenced practical application of the developed thermal spray coating in the ICFB®² in-layer heat transfer tube. |
3. Future developments
In its long-term vision E-Vision 2030, EBARA has set "contributing to the creation of a sustainable society" as an important issue. This technology is expected to be effective in suppressing the amount of wall loss of in-layer heat transfer tubes in an environment where corrosion and wear occur at the same time, and we believe that it will contribute to extending the life of plant components and promoting the use of renewable energy through biomass power generation.
EBARA Group aims to achieve the Sustainable Development Goals (SDGs) and further enhance its corporate value by addressing key ESG issues based on its long-term vision and medium-term management plan.
¹Erosion and corrosion: A phenomenon in which the "physical effect" of the flow of the environment (liquid phase or gas phase) and the "chemical (corrosion) effect" of the environment combine to accelerate the thinning of the material.
