Present Status of Additive Manufacturing for Metallic Components and Key Point from the Viewpoint of Corrosion Resistance

Shuji Hashizume

pp. 26-31

DOI:

10.3323/jcorr.73.26

Abstract

Recently, careful attention has been paid to additive manufacturing for metallic components. Additive manufacturing will be effective when a small amount of metallic components are necessary in short time. Additive manufacturing equipment for metallic components showed higher cost than that for plastic components. Therefore, cheaper methods have been recently developed. This report will focus to metallic components. Activity for utilize additive manufacturing in oil and gas industry and examination of corrosion performance are reported. Key points of producing superior corrosion resistant alloys metallic components by additive manufacturing will be discussed.

Assessment of Corrosion near Exposed Rebars in Reinforced Concrete Manhole

Yosuke Takeuchi, Ryou Makino, Junichirou Tamamatsu

pp. 32-36

DOI:

10.3323/jcorr.73.32

Abstract

Reinforced concrete structures are generally repaired when cracks or exposed rebar are detected. However, considering the shortage of maintenance personnel for infrastructure facilities, it becomes necessary to continue monitoring even after rebar exposure and predict the optimal timing for repairs. Therefore, in this study, accelerated tests using simulated rebar exposure specimens and field investigations of actual structures were conducted to evaluate the progress of corrosion after rebar exposure. As a result, it was found that localized deterioration preceded the corrosion in the exposed rebar and that the expansion of the corrosion area was limited.
