in order to enhance the performance of interconnects which are used in solid oxide fuel cells (sofcs), a protective/conductive coating can be applied. in this research aisi 430 ferritic stainless steel was coated in a mn-base pack mixture by pack cementation method. in order to evaluate the oxidation behavior, isothermal oxidation was accomplished for 200 h at 800 ºc. electrical behavior was al...

In order to enhance the performance of interconnects which are used in solid oxide fuel cells (SOFCs), a protective/conductive coating can be applied. In this research AISI 430 ferritic stainless steel was coated in a Mn-base pack mixture by pack cementation method.

Long–term stability and oxidation resistance of AISI 439 ferritic stainless steel used as interconnects in solid oxide fuel cells can be improved by use of a protective coating. In this study the pack cementation method was employed to coat AISI 439 ferritic stainless steel with manganese. Isothermal oxidation was conducted at 800 ºC for 200 hours in static air to investigate the role of coatin...

mold powders in continuous casting of steel contain fluorine through mainly caf2 and occasionally naf andna3alf6. fluorine develops dangerous gases such as sif4 and hf at high temperatures. in this study, caf2 is partly replaced by substances such as na2co3, zno and fe2o3.sulfur free portland cement clinker containing gypsum was used as a new product base. these additions developed comparable v...

Abstract This study successfully synthesized Li 2 MnSiO 4 /Mn 3 O (LMS/M3) and Mn 0.8 Ni 0.2 SiO (LMNS/M3) nanocomposites in a two-step method first, by preparing (M3) nanoparticles through hydrothermal second, synthesizing (LMS) (LMNS) ethylene diamine tetra-acetic assisted sol–gel method. In the last method, two are mixed hand-milling to form nanocomposites. Synthesized were characterized usi...
