“…Likewise, the composite coatings incorporating a variety of nanoparticles made up of nano-sized Alumina oxide [10][11][12], Zirconium oxide [13][14][15], Titanium oxide [16], Iron (III) oxide Fe 2 O 3 [17], Cerium Oxide CeO 2 [18] and carbides such as Silicon Carbide [19,20] and Tungsten Carbide WC [21] have enhanced anti-wear, anti-friction, anti-corrosion and mechanical properties. In addition, in composite coatings/materials the concentration of reinforcement content of nanoparticles is an important factor to obtain optimum tribological properties.…”

This paper presents research findings on the tribological performance of electrodeposited coatings subject to nano-lubricants with the addition of nano-Al 2 O 3 and graphene and Ni/nano-Al 2 O 3 composite coatings. Electrodeposited coatings were produced by using a pulse electrodeposition method. Tribological experiments were conducted by using a linear reciprocating ball on flat sliding tribometer. Experimental results confirm that the wear and friction resistance properties have been significantly enhanced by doping of nano-effects in the lubricating oil and composite coating. The addition of Al 2 O 3 nanoparticles in the lubricating oil showed the best tribological properties, followed by Ni-Al 2 O 3 composite coatings and nano-oil with graphene. The surface morphology and microstructure of electrodeposited coatings were examined by using a Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and X-ray Diffraction (XRD). The wear mechanisms of these coatings subjected to tribological testing were investigated by post-test surface analyses. This research provides novel approach to design durable nano-coatings for tribological applications in various industries such as automotive, aerospace, locomotive and renewable energy technologies.

“…The reported results are in agreement with the findings of other researches such as Omrani et al 10 who observed the increase in flexural properties at low loadings of up to 2 wt.% nano alumina to epoxy and when the level of loading was over 2 phr, the flexural modulus is decreased. On similar lines, Dass et al 18 reported the increase in flexural strength up to 10 wt.% micro alumina epoxy composite and reduction thereafter. Another study by Mahapatra and Patnaik 22 also noticed that addition of 10 wt.% alumina to polyester resin improves the flexural strength but further addition causes reduction in strength.…”

“…The reduction in strength at higher loading may be due to the conglomeration of filler particles resulting in stress concentration leading to failure. Dass et al 18 also reported the increase in tensile strength of Al 2 O 3 -Epoxy composite from 5 to 10 wt.% and decrease at a filler content of 15 wt.%, whereas another study 15 reported the increase in tensile strength of nano composite of Al 2 O 3 -monomer casting nylon up to 3 wt.% but decrease in tensile strength with increase in particle size from nano to micro. Guo et al 19 also observed the increase in tensile strength by 60% for 3 wt.% nano alumina vinyl ester composite.…”

Composite of Nylon 66 with different proportions of microparticle Al2O3 were made by compounding on a twin screw extruder. The sliding wear and mechanical properties of the resulting microcomposite of 2 to 8 wt.% Nylon 66–Al2O3 were investigated. The study of sliding wear under different loads, velocity and sliding distance combinations was done using pin-on-disk equipment. The results show that wear rate reduces with addition of microparticles and lowest wear is exhibited by 2 wt.% Al2O3–Nylon 66 composite. The lowest friction coefficient is also observed for 2 wt.% Al2O3-Nylon 66 composite and the value increases with increasing load, sliding velocity and sliding distance. The mechanical properties such as flexural strength and modulus, tensile strength and modulus, compressive and impact strength improved with the addition of alumina and maximum values are observed for 6 wt.% composite. The heat deflection temperature of the microcomposite increased with increasing weight % of alumina. Scanning electron microscopy images of the worn surfaces were examined to understand the wear mechanism. The improved mechanical and tribological properties of Nylon 66–Al2O3 composite will enhance the application of plain Nylon 66.

“…Therefore, when the sliding velocity was higher, which caused a rise of friction temperature, the viscosity of the surface layer would decrease. Hence the COF was lower [11]. The normal force has the same effect of sliding velocity.…”

Polymers and their composites are being increasingly employed in view of their good strengths and corrosion resistance. The features that make the polymer composites in industrial applications are the opportunities to tailor their properties with special fillers. For instance, short carbon and glass fibers have been successfully employed to improve the strength and therefore the load carrying capacity of polyamide composites can also be improved Optimization of parameters is an important in the tribological process. Response surface methodology (RSM) based optimal parameter analysis was performed to investigate the change of responses like wear rate (WR) and coefficient of friction (COF) with the change of input parameters to determine optimum setting of process parameters such as normal force, sliding velocity and reinforcement for achieving minimum WR and COF. The regression model generates the response surfaces. The present study is to optimize the parameter setting for combined responses.
