“…Therefore, some AMCs have been made using a type of filler material containing SiO2 compounds such as silica sand, rice husk ash, and others. This is considering that SiO2 compounds have the advantage of being relatively hard and light and thus are often used as filler powder reinforcement in the manufacture of composites or as coatings [10,11]. The aim of their overall research is to be applied as a replacement material for Asbestos-based friction brakes.…”

Due to the increased demand for aluminium and the prohibitive cost of producing primary aluminium, the process of making AMCs using recycled aluminium alloy as a matrix and silica sand tailing without leaching as a filler is essential to be developed. For more cost-effective, the purpose of this study is to make particulate aluminium composite matrix AMCs with a matrix of recycled aluminium and reinforced with silica sand tailing without leaching. This research involves the effect of differences in grain size and filler weight percentage on matrix Al-ZnSiFeCuMg recycled aluminium alloy powder. This study used powder metallurgy technology as well as two-way hot-compaction (300°C) and applied a sintering temperature of 550°C. Density, hardness, and wear testing, as well as microstructure analysis, were conducted to determine the characteristics of the resulting AMCs. An increase in hardness of 67% was achieved by the AMCs-164 µm-20%SiO2 specimen, which used a filler grain size of 164 µm wt.20%. Meanwhile, AMCs-31 µm-20%SiO2, which used a filler grain size of 31 µm, only increased by 63%. The wear test result also showed a lower wear rate achieved by the AMCs-164 µm-20%SiO2 specimen. The results analyses using SEM-EDS instruments showed higher agglomeration and porosity in specimens using a filler grain size of 31 µm, while AMCs using a filler grain size of 164 µm showed an even spread of filler powder. Therefore, AMCs that used 164 µm powder-sized fillers have a stronger bond between the filler and the matrix and produce AMCs that are harder than AMCs that use 31 µm fillers.

“…When the content of bio-silica are increased from 1wt% to 10 wt%, into the bio-silica reinforced DGEBA-IMA composites, the increase in R ct and decrease in double layer capacitance values were observed. It infers an improvement of corrosion resistance behavior which arises from the reduction of pores/cavities present in the polymer coating which could be occupied by the bio-silica [10][11][12]. The roughness' factor values (n) are continuously decreasing while increasing weight percentage of bio-silica into the polymer matrix which also corroborates the reduction of pores/cavities on the mild steel surface.…”

Imidazole core monoamine (IMA) was synthesised and used as a hardener for epoxy resin. The epoxy resin was reinforced with varying weight percentages of 3-glycidoxypropyltrimethoxysilane (GPTMS) functionalized rice husk ash bio-silica to obtain respective composites. Their composite morphology was studied using SEM analysis. The cure behaviour of imidazole core diamine hardener and DGEBA epoxy resin was studied. The thermal stability of the corresponding epoxy matrix and bio-silica reinforced epoxy composites were studied by thermogravimetric analysis (TGA). The values of limiting oxygen index calculated from TGA data infer that all the samples of epoxy matrix and composites possess good flame retardant behaviour. In order to ascertain their hydrophobic behaviour, the water-contact angle measurement studies were carried out. The values of contact angle obtained for neat IMA/DGEBA matrix is 84°, where as that of 1, 3, 5, 7 and 10wt% bio-silica reinforced IMA/DGEBA are 87°, 90°, 93°, 95° and 98° respectively. IMA/DGEBA matrix and functionalised bio-silica reinforced IMA/DGEBA composites were coated on the mild steel specimens and their corrosion resisting behaviour was studied by electrochemical impedance spectroscopy and potentiodynamic polarisation. Data resulted from corrosion studies (Nyquist plot and Tafel plot) inferred that among the coated specimens studied, the specimen coated with 7 wt% bio-silica reinforced IMA/DGEBA matrix exhibits the highest corrosion resisting efficiency due to its water repellent character and morphology.

“…5 In order to reduce the corrosion, many polymeric/organic materials have been coated on the surface of metal which shows effective anticorrosion behaviour. [6][7][8][9] However, majority of the polymeric coatings possess less stability toward thermal energy. As all metals are good conductor of thermal energy, they get heated easily and the coatings will begin to peel off from the surface.…”

New trifunctional polybenzoxazines were developed and utilized as a high‐potent coating material for superhydrophobic cotton fabrics and mild steel corrosion protection applications. New trifunctional benzoxazines resin have been synthesized using trihydroxytriphenylmethane (TTM) with dimethylaminopropylamine (dmapa), 1‐(3‐aminopropyl)imidazole (ipa) and aminoethoxyethanol (aee) as amine sources with paraformaldehyde through Mannich condensation. The structural confirmation of synthesized benzoxazines was ascertained by spectral studies. The ring opening polymerization of TTM‐Bzs was studied using DSC analysis. All the three TTM‐Bz monomers show curing temperature lower than 210°C. The thermo‐stability and water contact angle (WCA) of polybenzoxazines were studied using thermogravimetric analysis and goniometer, respectively. Among the TTM‐PBz studied, the poly(dmapa) exhibit better thermo‐stability and hydrophobic behavior when compared to rest of the synthesized polybenzoxazines. Poly(TTM‐dmapa)‐coated cotton fabric exhibits the superhydrophobic behavior and mild steel (MS)‐coated specimen possesses the higher charge transfer resistance value of 3.47 × 107 Ω cm2. It was also inferred that all the TTM‐PBz‐coated MS specimens exhibit higher corrosion protection behavior as well as good thermo‐stability and hydrophobic nature. Further, the obtained results suggested that these materials can be suitably exploited for hydrophobic anticorrosion applications with improved performance and enhanced longevity.
