“…In recent years, carbon nanomaterials have emerged as reinforcement phases for improving tribological behaviors of the coating systems [1,3]. In particular, carbon nanomaterial-enhanced coatings have been shown to own low friction coefficients and excellent antiwear abilities under severe working conditions, such as extreme pressures, high speeds, and ultimate vacuum [44,45]. In this section, current developments on the friction and wear performances of coatings reinforced with fullerenes, CNTs, graphene, and NDs have been systematically summarized.…”

In recent years, carbon nanomaterials such as fullerenes, carbon nanotubes, graphene, and nanodiamonds have been regarded as versatile triboproducts such as copper coins for various engineering/commerce-scaled applications. Their large-scale usages as ideal reinforcements for the key tribomaterials are motivated by their huge interfacial areas, unique physical/chemical characteristics, as well as multiple scale load-transferring mechanisms. Numerous investigators have kept on studying the possibilities of using carbon nanomaterials as solid lubricants, lubricating additives, or the superlubricated push hand. This review offers a comprehensive discussion of up-to-date survey in carbon nanomaterials for achieving the low friction and high wear resistant in the forms of coatings, bulk materials, lubricants; or even superlubric state in the tribosystems from nanoscale to macroscale. Finally, important conclusions, foreseeable challenges, and future outlooks for carbon nanomaterials are highlighted as the concluding remarks that are needed to impulse nanotechnology maturation and developments of tribological fields such as copper coin protections.

“…Subsequently, the samples were immersed in zinc dipping solution to obtain zinc layer with the purpose of improving the adhesion between the magnesium alloy substrate and the copper layer and preventing the magnesium alloy substrate from corrosion in the copper plating solution. In the end, the surface of the magnesium alloys was plated with copper as undercoat layer by electroless, which can improve the adhesion between the substrate and the Ni-W-P coatings 34 . The formulas and operating conditions of zinc dipping and copper preplating are shown in Table 1 and Table 2 respectively.…”

Ni-W-P ternary coating was successfully deposited on AZ91D magnesium alloy by electroless plating with low energy consumption. The effect of Na 2 WO 4 concentration on the microstructure, deposition rate, corrosion behavior, adhesion force, porosity test and micro-hardness of Ni-W-P ternary coatings were evaluated. Results reveal that when the concentration of Na 2 WO 4 is 15 g/L in the plating solution, the coating with the average thickness of 17 μm is uniform and dense, and the content of phosphorus and tungsten reached 9.63 wt.% and 1.14 wt.% respectively, which presents amorphous structure. Meanwhile, when the concentration of Na 2 WO 4 is 15 g/L, the amorphous Ni-W-P ternary coating has the best corrosion resistance, among which E corr is -0.326 V, I corr is 0.003 A/cm 2 in 3.5 wt.% NaCl solution. In addition, the mechanisms of corrosion resistance for the substrate and the coating were exploded.

“…With the aid of portable instrumented micro-indentation devices, instrumented indentation testing (IIT) has been widely used to evaluate the mechanical behavior of in-service engineering structures, such as high-speed rail [1,2], pipelines and turbine rotors [3]. In laboratories, IIT were also applied on metals [4,5], ceramics [6,7], coatings [8,9], shape memory alloys [10], etc, to determine mechanical parameters such as indentation hardness [11,12], elastic-plastic parameters [13][14][15], fracture parameters [16] and indentation activation volume [17]. Theoretically, to increase the accuracy in the determination of elastic modulus and indentation hardness, the surface of the sample to be tested should be mirror-flat.…”

Although, surface roughness can influence the determination of elastic moduli and indentation hardness to some extent by instrumented spherical indentation test, limited work has been done to quantitatively reveal and minimize these influences. In the present work, through a large number of finite element (FE) simulations and analyses, we clarified the evolution trend of determined elastic moduli and indentation hardness corresponding to different normalized indentation depths (h/R) and normalized roughness (Sq/R). On this basis, an area correction method was proposed to improve the measurement accuracy in the elastic moduli and indentation hardness. The FE results show that, with the newly proposed correction method, the maximum relative error in determined elastic moduli is reduced from about ±7% to ±2%, and that in the determined indentation hardness is reduced from about ±13% to ±5%, when Sq/R ≤ 2.2 × 10-3 and h/R = 5%. Applications were then illustrated on four typical metallic materials (i.e., AA 7075, AA 2014, steel 316L, and copper T2). The experimental results demonstrate that the proposed correction method is able to mitigate the effects of surface roughness on the determination of elastic moduli and indentation hardness to obtain more correct results.
