High temperature oxidation of Co-W electroplated type 430 stainless steel for the interconnect of solid oxide fuel cells

Autor: Isao Saeki, Hideyuki Murakami, Lu Gan

Publikováno v: Corrosion Science. 134:162-168

Cobalt–tungsten alloy layer containing 2.4 at% W was electroplated on type 430 stainless steel (Fe–16 mass% Cr), and it was subjected to high-temperature oxidation at 800 °C in Air–3 vol% H2O atmosphere for 1000 h. A five-layered oxide of Co3O

The Effect of Cr on the Lifetime of Al-Rich Amorphous Oxide Layer Formed on Fe–Cr–Al Alloys at 650 °C

Autor: Shigeharu Ukai, Suzue Yoneda, Shigenari Hayashi, Isao Saeki

Publikováno v: Oxidation of Metals. 88:669-686

The oxidation behavior of Fe–6Al with different Cr contents (0–24 at.%) at 650 °C in air was investigated so as to clarify the role of Cr in the oxidation resistance of the Al-rich amorphous oxide layer. The time to breakdown of the Al-rich amor

Microstructure and area specific resistance of cathodic half cells for solid oxide fuel cells composed of perovskite-type cathodes and Co-alloy-coated ferritic stainless steel interconnects

Autor: Xabier Montero, Isao Saeki, Saad Ahmed Sheikh, Hideyuki Murakami, Lu Gan

Publikováno v: Surface and Coatings Technology. 406:126659

In order to prevent oxidation and Cr poisoning, a Co-W coating has been applied on ferritic stainless steel (FSS), which is used as the interconnect parts of solid oxide fuel cells (SOFCs). However, the electrical properties of the Co–W-coated stai

Investigation of Initial Transient Oxidation of Fe–xCr–6at.%Al Alloys Using Synchrotron Radiation During Heating to 1000 °C in Air

Autor: Isao Saeki, Shigeharu Ukai, Suzue Yoneda, Shigenari Hayashi

Publikováno v: Oxidation of Metals. 86:357-370

The initial oxidation behavior of Fe–6Al alloys with different Cr contents (0–24 at.%) during heating to 1000 °C at 50 °C/min, followed by isothermal oxidation for 1 h, was investigated by means of synchrotron radiation in order to clarify the

Thermal stability of the CoWO4 layer formed on ferritic stainless steel

Autor: Hideyuki Murakami, Toshiyuki Nishimura, Lu Gan, Isao Saeki, Saad Ahmed Sheikh

Publikováno v: Corrosion Science. 176:109037

This study focuses on the temperature capability of CoWO4 as the oxidation protection layer of ferritic stainless steel (FSS). The thermogravimetric-differential thermal analysis revealed that until CoWO4 started to melt at 1297 °C, little mass chan

Ni electroplating on AZ91D Mg alloy using alkaline citric acid bath

Autor: Takahiro Seguchi, Yuya Hayashi, Yusuke Kourakata, Isao Saeki

Publikováno v: Electrochimica Acta. 114:827-831

Electroplating of Ni on an AZ91D Mg alloy in alkaline citrate baths was studied. It was found that NiSO4 and citric acid form a soluble complex. Ni plating with a smooth surface was obtained from the bath containing 0.55 mol dm −3 of nickel sulfate

Publikováno v: Materials and Corrosion. 63:862-868

The effect of oxygen partial pressure on the phase transformation of Al2O3 scale on various Fe–Al alloys with and without very thin (∼100 nm) Fe coating was investigated. Fe-coating on Fe–Al alloys can effectively suppress metastable Al2O3 form
