“…Iron foam is one type of solid metal with very low density since it contain high volume fraction of pores with 75-95% of its volume is empty. Due to its very high porosity, this material has high compression strength and high energy absorber characteristic as well [1][2][3][4]. Based on these facts iron foam has been widely applied for various application such as for applications, which require load bearing characteristic, vibration and sound damper, filter, high temperature catalyst, implant material [5] and for the inner part of vehicle frame to reduce the weight of vehicle.…”

Iron foam is iron based material which is widely applied due to its unique properties. However since corrosion is also a problem for this material, coating with innert material is required in enhancing its applications. In the present research, TiO 2 coating is performed on iron foam suface by sol-gel dipping method. Focus is given on the study of the effect of calcinations temperature and time on the coating characteristics. TiCl 4 is used as the precursor with concentration of 0.3 M, added with 1M HCl solution and chitosan soluation with concentration of 1%. Calcination is performed at temperature of 400, 500 dan 600 o C and calcinations time of 1 and 3 hours inside controlled gas furnace using nitrogen atmosphere. Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) characterization data shows that TiO 2 particles form on the iron foam substrate. SEM characterization on the sample heated at 400 o C and heating time of 1 hour shows the formation of nano particle titania (0.06 μm) which is homogeneously distributed with less agglomeration than others and considered as the best sample in the present research. As the temperature and time of calcinations increase, more inhomogeneous particle distribution and bigger particles form.

“…The materials applied to such filters should have the high oxidation resistance at an elevated temperature and the controls of shape and size of pores were also important factors for industrial application. The industry has usually employed the ceramic material for filtering materials because of its high thermal stability, but the application of metallic filter has comparatively increased owing to its good flexibility [1][2][3].…”

Porous metal with uniform honeycomb structure was successfully produced by sintering using Fe-Cr-Al nano powder, which was prepared by the pulsed wire evaporation (PWE) in ethanol. Its process consisted of the several steps; 1) coating on the surface of polyurethane sponge with the liquid droplets generated from the ethanol-based slurry where the Fe-Cr-Al nano powders were uniformly dispersed, 2) heat treatment of debinding to remove the polyurethane sponge and 3) sintering of the porous green body formed by Fe-Cr-Al nano powders. The strut thickness of porous Fe-Cr-Al was increased by the increase of spraying times in ESP step. Also, The shrinkages and the oxidation resistance of the sintered porous body was increased with increase of sintering temperature. The optimal sintering temperature was shown to 1450• C in views to maximize the oxidation resistance and sinterability.
