Autor: Poonam Yadav, Muhammad Ali Abro, Dong Bok Lee, Jonghun Yoon
Publikováno v: Journal of Materials Research and Technology, Vol 17, Iss , Pp 3055-3065 (2022)
In this work, the high-temperature corrosion behaviour of pure Ni3Al (P–Ni3Al) and alloyed (2.99 wt.%Ti) Ni3Al (Ti–Ni3Al) was investigated in Ar-0.2%SO2 gas at 900–1100 °C for up to 100 h. The corrosion kinetics of P–Ni3Al and Ti–Ni3Al rev

Corrosion of Multilayered TiAlSiN Films at 800–1000 °C in N2/0.1%H2S Gas
Autor: Xiao Xiao, Muhammad Ali Abro, Dong Bok Lee, Junhee Hahn
Publikováno v: Metals and Materials International. 27:3260-3268
A multilayered TiAlSiN thin film consisting of alternating nanocrystalline Ti(Si)N and Al(Si)N nanolayers was deposited on steel by arc ion plating. The film composition was 26Ti–16.3Al–1.2Si–56.50N in at%. The film was corroded at 800–1000

Long-time Oxidation of Ti3(Al,Si)C2 Carbides at 400-800 oC
Autor: Dong Bok Lee, Sang Whan Park, Junhee Hahn
Publikováno v: Korean Journal of Metals and Materials. 58:182-189
Quarternay carbides of Ti3AlxSi1-xC2 (x=0.3, 0.5, and 0.7) were oxidized at 400, 600, and 800 °C for 0.5-6 months in order to study their long-time oxidation behavior in air. When they were oxidized at 400-600 oC for 0.5-3 months, oxidation proceede

Corrosion of Fe-Cr and Fe-Cr-Ni Alloys at 700-800°C in CO2-0.3SO2-6O2 Mixed Gas
Autor: Kyong Hwan Lee, Min Jung Kim, Xiao Xiao, Dong Bok Lee
Publikováno v: Key Engineering Materials. 833:85-89
ASTM T22 (Fe-2.25Cr-1Mo), 347HFG (Fe-18Cr-11Ni), and 310H (Fe-25Cr-19Ni) steels were reacted with CO2-0.3SO2-6O2 mixed gas. During corrosion at 700-800 °C for 20-100 h, 347HFG (Fe-18Cr-11Ni), and 310H (Fe-25Cr-19Ni) steels had good protective Cr2O3
