[ 1 ] - Isothermal and cyclic oxidation behavior of AISI 430 ferritic stainless steel coated with titanium
In order to improve the oxidation resistance of ferritic stainless steel, it is possible to deposit a protective coating on steel substrate. In this research through the usage of pack cementation method a coating of titanium was applied on the surface of AISI 430 stainless steel. Scanning Electron-Microscopy (SEM), Energy- Dispersive X-ray spectrometry (EDAX) and X-ray diffraction (XRD) were us...
[ 2 ] - Oxidation and Electrical Behavior of Crofer 22APU Steel with the Co/Y2O3 Coating Produced by Direct Electroplating
Crofer 22 APU ferritic stainless steel has been evaluated as one of the favorable materials for utilization in Solid oxide fule cell (SOFC) interconnects. However, there are difficulties in utilizing these metallic interconnects, including the quick decrease of their electrical conductivity and evaporation of Cr species. To overcome the above problems, the application of protective coatings ha...
[ 3 ] - Investigation on the Microstructure, Oxidation and Electrical Behavior of Ti-coated Crofer 22APU Steel for SOFC Interconnect Applications
One of the most effective ways to improve oxidation resistance of interconnects used in solid oxide fuel cells (SOFCs) is to apply a layer of conductive protective coating. In this study, Crofer 22APU ferritic steel was coated in a titanium- based powder mixture by pack cementation method. The powder composition for titanium coating was Ti 20 wt.%, NH4Cl 5 wt.% (activator) and Al2O3 75 wt.%. Th...
[ 4 ] - The Impact of Current Density of Electroplating on Microstructure and Mechanical Properties of Ni-ZrO2-TiO2 Composite Coating
Metallic composite coatings with ceramic particles can be used to improve the mechanical and corrosion properties of steel. In the present research, Ni-ZrO2-TiO2 composite coating was fabricated on AISI 430 stainless steel through the electrodeposition method. The effect of the current density of electroplating (15, 17, 20, and 23 mA.cm-2)was investigated on the...
[ 5 ] - تأثیر pH آبکاری بر میکروساختار و خواص مکانیکی پوشش کامپوزیتی Ni-P-TiO2 ایجاد شده بر روی فولاد AISI 430
یکی از بهترین روشهای مؤثر برای بهبود مقاومت به سایش و سختی فولادهای زنگ نزن اعمال پوششهای سطحی است. از جمله این پوششها، پوششهای آلیاژی و کامپوزیتی پایه نیکل هستند. در این تحقیق، پوشش کامپوزیتی نیکل- فسفر- اکسیدتیتانیوم با استفاده از روش آبکاری الکتریکی بر روی فولاد زنگ نزن AISI 430 ایجاد شد. تأثیر pH آبکاری (3، 5/3 و 4) بر روی میکروساختار و میکروسختی و رفتار سایشی آن‌ها مورد بررسی قرار گرفت...
