“…An optimised Watt's bath chemical composition was used for deposition process based on previous findings [12]. For the development of nano-enhanced composite coating, alumina nanoparticles (40-50nm) (supplied by Lo-Li-Tech) were added into an electroplating bath under continuous magnetic stirring process.…”

“…This is because of better particle distributions and relatively refined compact microstructure of nano-alumina composite coatings. Previously, the effect of chemical solution concentration on the tribological performance of pure nickel and nickel alumina composite coatings was investigated [12]. It was found that the ionic strength of electrolyte has significant influence on the tribological and mechanical properties of electrodeposited coatings.…”

“…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 corrosion resistance, tribological performance and film characteristics have been reported [10][11][12][13]. The crystalline structure of film materials and thin film porosity are not subjects of this review as the phenomenon of corrosion diffusing species through micro cracks in thin films have been reported [14][15][16][17][18][19][20][21] in detail.…”

This paper contains a review of the most vital concepts regarding the analysis and design of film systems. Various techniques have been presented to analyse and predict the failure of films for all common types of failure: fracture, delamination, general yield, cathodic blistering, erosive and corrosive wear in both organic and inorganic films. Interfacial fracture or delamination is the loss of bonding strength of film from substrate, and is normally analysed based on the fracture mechanics concepts of bi-material systems. Therefore, keeping the focus of this review on bonding strength, the emphasis will be on the interfacial cracking of films and the corresponding stresses responsible for driving the delamination process. The bi-material characteristics of film systems make the nature of interfacial cracks as mixed mode, with cracks exhibiting various complex patterns such as telephone cord blisters. Such interfacial fracture phenomenon has been widely studied by using fracture mechanics based applicable analysis to model and predict the fracture strength of interface in film systems. The incorporation of interfacial fracture mechanics concepts with the thermodynamics/diffusion concepts further leads to the development of corrosive degradation theories of film systems such as cathodic blistering. This review presents the suggestions for improvements in existing analysis techniques to overcome some of the limitations in film failure modelling. This comprehensive review will help researchers, scientists, and academics to understand, develop and improve the existing models and methods of film-substrate systems.

This research work describes the effect of dispersed titanium carbide (TiC) nanoparticles into nickel plating bath on Ni/TiC nanostructured composite layers obtained by electro-codeposition. The surface morphology of Ni/TiC nanostructured composite layers was characterized by scanning electron microscopy (SEM). The composition of coatings and the incorporation percentage of TiC nanoparticles into Ni matrix were studied and estimated by using energy dispersive X-ray analysis (EDX). X-ray diffractometer (XRD) has been applied in order to investigate the phase structure as well as the corresponding relative texture coefficients of the composite layers. The results show that the concentration of nano-TiC particles added in the nickel electrolyte affects the inclusion percentage of TiC into Ni/TiC nano strucured layers, as well as the corresponding morphology, relative texture coefficients and thickness indicating an increasing tendency with the increasing concentration of nano-TiC concentration. By increasing the amount of TiC nanoparticles in the electrolyte, their incorporation into nickel matrix also increases. The hybrid Ni/nano-TiC composite layers obtained revealed a higher roughness and higher hardness; therefore, these layers are promising superhydrophobic surfaces for special application and could be more resistant to wear than the pure Ni layers.
