This research focuses on the synthesis and analysis of the dynamic properties of a bamboo fibre used with a polyester matrix in a nanocomposite produced with titanium oxide nanoparticles. Bamboo-fibre samples were prepared using the electroless plating method in both their uncoated and nickel-phosphorus-coated states. Bamboo-fibre contents of (4.5, 9, 13.5 and 18) w/% and nanoparticles of (0.5, 1, 1.5 and 2) w/% with and without the coating were examined for these qualities. Coated bamboo fibres were mixed with 13.5 w/% and 1.5 w/% of titanium oxide. It was concluded that dynamic and thermomechanical properties of the polyester matrix reinforced with bamboo fibres coated with nanoparticles allow excellent bonding as compared to the nanocomposite of the polyester matrix reinforced with uncoated bamboo fibres.

Nano Iron oxide is introduced into the matrix as fillers at the minimum concentration and its influence on the mechanical and wear behavior are studied. The nano additive added to play a major role in strengthening the composite. To further enhance the strength and wear resistance, polyvinyl ester matrices reinforced with electroless NiP coated glass fiber reinforcement is synthesized. The glass fiber reinforcement is coated for the first time into electroless NiP successfully after carrying out many trials. The surface morphology is examined by means of SEM. The experimental result shows that after coating the reinforcement with electroless NiP , the ultimate tensile strength, compressive strength, flexural strength, impact strength and wear resistance is improved by 17.90%, 9%, 12.98%, 33% and 4.58% respectively.

The two surfactants namely sodium dodecyl sulfate (SDS) and cetyltrimethyl ammonium bromide (CTAB) have significant influence on the structure of EN deposits. The EN coated samples were characterized using X-ray diffraction analysis (XRD) and transmission electron microscopy (TEM). The XRD pattern of all the deposits indicated the presence of nano crystalline and amorphous phases. Addition of surfactants favors the formation of amorphous phase than its crystalline counterpart. The crystallite size was found to varyfrom 20 nm with no surfactant to 8 nm with addition of surfactants. From the TEM study, dark surfaces corresponding to the amorphous phase can be seen and the SAD pattern of the deposit confirms the predominance of this amorphous phase. This favors wear and corrosion resistance applications. The experimental results and analysis are reported in this paper.

Nano additives such as ZnO, Al2O3 and CuO were added at various concentrations of 0.1%, 0.5%, 1%, and 2% in the EN-P bath and their influences on coating process characteristics were studied. The output parameters such as mechanical, characterisation and corrosion resistance evaluations were measured. The investigation proved that the suggested method resulted in substantial improvement on the quality of the coatings developed. The evaluation was reported at 1 % concentration of Nano additives in the bath. The overall performance of Nano Al2O3 in the En-P bath resulted in significant improvement on the corrosion resistance and quality of the coating produced as compared to other Nano additives.

The examination for the rate of corrosion in low alloy steel pipelines included a range of coated samples that includes organic paint, metallic paint, Aluminum, Zinc and electroless ones. After the samples were coated, the surface roughness was checked and the coating thickness maintained. For corrosion rate analysis and the evaluation of each coating's life period, a number of test including atmospheric exposure test, dry and wet test and potentiodynamic test were conducted. In order to analyze the surface behavior of coatings, characterization was performed with SEM-scanning electron microscope that later supported with hardness test results. The performance analysis of several coatings investigates that, mixture of nano Al 2 O 3 additive with Aluminum paint gives the best result against corrosion and presented good surface performance in comparison with other samples.
