“…As aforementioned, the agglomeration lead to crack propagation due to weak adhesion of filler matrix. The findings by previous studies had found that the agglomeration had affected the tensile strength as agglomeration led to crack propagation growth due to high stress attention on that area and lack of filler matrix adhesion [17,[21][22]. As viewed in CA POS composites schematic, the red circle represent the agglomeration which had led to tensile failure due to stress attention and led to crack propagation.…”

The effect of fabrication methods on polysiloxane (POS) composites were studied by analysing both method of casting (CA) and compression (CO). The POS composites were reinforced with 2-12 wt% of natural derived silica from rice husk (RHA SiO2) as a filler which incinerated at 700°C. The composites behaviour were analysed through tensile testing (ASTM D412). Through comparison study on both CA and CO composites’s tensile behaviour it shows that both composites strength keep increasing with 2wt% - 10wt% RHA SiO2 addition but strength decreased at 12wt% due to agglomeration of RHA SiO2. Moreover, it was found that the tensile strength of CO composites had offer 23.56% higher compared to CA composites. The difference were influenced by the distribution of RHA SiO2 as filler. The surface morphology of CO composites had showed that the most of RHA SiO2 were embedded and less agglomeration, compared to CA composites that had lots of agglomeration which lead to higher tendency of crack propagation. The arrangement of filler due to the CO method that helps RHA SiO2 to distributed homogenously and embedded in a matrix of POS to avoid agglomeration and lead better adhesion respectively. Thus, CO method had potential to offer in enhancing tensile behaviour compared to CA method by influencing filler distribution arrangement for vibration absorber application.

“…This means that the dispersal concentrations of Mn and Co cations in the layer are most likely in the same size order [25][26]. When a higher voltage is used for deposition, the surface layer becomes non-uniform because the particles' mobility energy becomes more energised, resulting in rapid particle movement on the steel substrate [27][28]. Since the particles are deposited quickly on the steel, the random particle arrangement does not scatter uniformly and consistently enough since the voltage is high and the coating time is low.…”

“…This may be due to the high mobility energy of particles, which allows the particles to migrate rapidly onto the steel surface and fail to bond properly [33,34]. This may be influenced by instability in the aqueous suspension as well as the forming of bubbles in the suspension [27,28,41]. Based on the Yohannes et.…”

Solid oxide fuel cell has become one of the interest in the sustainable energy field. In order to improve the efficiency of a solid oxide fuel cell (SOFC), the interconnect must be coated with a protective coating of (MnCO)3O4 spinel coated stainless steel. Commercial manganese cobalt (MnCO)3O4 was used as a protective coating on ferritic stainless steel in this study using the electrophoretic deposition (EPD) coating technique. This article examines the impact of voltage deposition towards morphological characteristics. The goals of these studies are to find the best interconnect coating parameter while experimenting with voltage deposition. The spinel coated interconnect (MnCO)3O4 was studied using Elemental Energy Dispersive X-ray Spectroscopy (EDS). The surface morphology and coating thickness are examined using a Scanning Electron Microscope (SEM). X-ray diffraction (XRD) is used to determine the phase of the spinel coated interconnect. The EPD coating technique for (MnCO)3O4 spinel coated interconnect is carried out in an aqueous suspension with 30V and 40V with coating durations of 20s, 30s, 40s, 50s, and 60s. By observing the deposition morphology and thickness coating at 30V and 40V, the best covering parameter for interconnect is 30V, 40s which fulfil the interconnect requirement.
