“…al., reported that the surface roughness of PSf membrane was increased by the addition of silver nanoparticles which is probably due to the effect of silver nanoparticles by disturbing the homogeneity of polymeric chains on the surface roughness [16]. The similar result agreed by Ahmad et al where the surface roughness was increased with the increasing of the peak current [17]. The addition of AgNO3 affected the LiOH behavior that can cause the membrane to reduce fouling performance.…”

Water is not only a personal demand. However, it is the most significant for human need throughout everyday life. To fulfill the need for water in the year of 2050, we can see the situation of the world water benchmark uncovers roughly 5500 km 3 of freshwater withdrawals will be required. All these requirements are including manufacturing, electricity production, and domestic use. The current global demand for this increase of about 55%, where the demanding of drinking water will be about 130% for households than volumes nowadays [1&2]. However, having some issue in the misuse of water resources and water contamination because of the quick advancement of the populace, there is a radically expanding issue in water shortage [3]. Subsequently, cost-effective innovations must be created to broaden water resources and solve water contamination issues. The membrane is one of the physical barriers that allow only water to pass through and prevent humic substances to infiltrate the barrier [4]. Membrane filtration is one of the advanced methods which is reported to be able

This study was a preliminary study in applying chitosan as coating for tinplate. Tinplate was used as the material for packaging because it was cheap, attractive, shiny, and easy to shape. Chitosan coating on tinplate with electrophoretic deposition (EPD) method and variation of EPD current was performed in this study. The variation of the current was 2, 4, 6,and 8A. Coating thickness was measured using NOVOTEST TP-1M. The surface roughness was tested using Mitutoyo Surface Roughness Tester SJ-210. The corrosion test applied the polarization method of PotentiodynamicAutolab PGSTAT 128N with Control software NOVA 1.11. The corrosion test of the specimen was run in 3.5% NaCl solution. The specimens without treatment had higher corrosion rate compared to the specimen with EPD current of 8A which was 0.00061927 mpy. At the current variation of 8A, the coating thickness was 78.9 ± 1.58 %.The higher the current used in the EPD, the lower the corrosion rate was. It was indicated by coating that protected the tinplate and produced homogeneous coating. This was in line with the result of surface roughness which decreased along with the increase of EPD current. The lowest surface roughness was at variation of 8A which was 0.152 µm.

“…Electrochemical machining (ECM) and Electrical discharge machining (EDM) provides an exceptional way to produce a 3D complex shape features and component (micro and macro) for hard to machine materials such as steel, carbides, titanium alloys and super alloys such as Inconel [55][56][57], and suitable for conductive and nonconductive materials [46]. Furthermore, because these processes are a non-contact process, it will prevent tool deformation and breakage and therefore suitable for micromachining that is using small size tools [46].…”

“…EDM is able to fabricate smaller feature dimensions (less than 100mm), complex geometry structure, smoother surface, lower machining force and avoid mechanical stress on a work piece. However, EDM also possesses some limitations such as low material removal rate [56][57], small value roughness, re-solidify of molten material on the surface and unable to conform work piece dimension because of the tool do not come in contact with the work piece. For the micro-EDM process, there are different types available such as micro-wire EDM, micro-electric discharge milling, die-sinking micro-EDM and micro-electric discharge drilling [76].…”

This paper presents a brief review of surface texturing with a focus on piston assembly application. The paper begins with a general discussion on surface texturing and the manufacturing process of micro dimples. Further, it discusses the theory of hydrodynamic lift generation and the effect of parameters of micro dimples texture on the surface-to-surface friction. Finally, the effect of surface texturing on heat transfer is briefly discussed. In pursuits to improve internal combustion engine (ICE) efficiency, tribological improvement of moving surfaces by means of micro surface texturing seems to be one of the way. However, texturing parameters have to be carefully designed as it can cause detrimental effect if the designs are wrong. Studies has shown micro surface texturing at piston ring could reduce friction around 20%-50% compare with un-textured piston ring and also reduce fuel consumption at 4%. Micro Surface texturing could also improve heat transfer between the surfaces to reduce piston slap and lubrication oil temperature. As reports on the surface texturing on friction reduction and heat transfer improvement in piston assembly are relatively scarce, it is suggested that optimization of micro dimple parameters for piston skirt application and its effect on engine tribology and heat transfer characteristics to be further investigated.
