“…10 and 11). These results indicated that the carbon bers formed a solid lubricant lm on the worn surfaces thus preventing seizure of the matrix with the counterpart, as previously reported regarding the wear behavior of the aluminum composite reinforced with the PANbased carbon ber, graphite ber and graphite ake [5][6][7]9,10) . Due to the microscopic roughness, the direct contact area on the contact face between the pin (aluminum) and disk (counterpart) specimens would be limited.…”

The effects of carbon ber-reinforcement on the wear behavior of aluminum alloy under a dry sliding conditions have been investigated. Two kinds of carbon bers, PAN-based and pitch-based short carbon bers, were used as the reinforcements. The composites were fabricated by squeeze casting, and wear testing was carried out using the pin-on-disk method. The wear loss of the alloy and counterpart decreased due to the ber-reinforcement. The change in the coef cient of friction during the wear test and the scatter in the roughness of the worn surface also decreased by the reinforcement. Examination of the worn surfaces and temperature change of the specimens during the wear revealed that these results were mainly attributed to the crumbled bers forming a solid lubricant lm on the worn surfaces thus preventing seizure of the matrix with the counterpart. Under a high load and sliding speed, the wear loss of the pitch-based ber composite was lower than that of the PAN-based ber one. The examination described above revealed that the improvement in the wear and seizure resistance was mainly attributed to the higher thermal conductivity of the pitch-based ber composite.

“…XRD results are extended from the earlier reported work [15] in which the tribological performance of various nanocomposite was investigated. This research is a continuation of existing work in terms of enhancing tribological and anti corrosive properties in harsh environment [28][29][30][31][32][33][34][35][36][37][38][39][40][41].…”

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 diameter of each carbon fibre in the rod was 5 µm and these carbon fibre rods were subjected to an electroless nickel coating as reported in our earlier works after proper pre-treatment and sensitization [16]. The electroless nickel coated carbon rods were then coated with copper using conventional copper electroplating bath, with its composition maintained as per standards reported in literature [17].…”

Today, in the world of materials the focus is on the development of metal matrix composites (MMC's), particularly aluminium based composites due to its widespread applications in aerospace and automobile industries. To develop light weight MMC's, carbon fibres in both continuous and dis-continuous forms are used as reinforcements. The processing and characterization of mechanical and adhesive wear behaviour of various composites are widely practiced by various researchers around the world. However, solid erosion wear of continuous carbon fibre reinforced MMC's has not yet been reported. In the light of the above, the present work focuses on characteristics of erosive behaviour of Al6061-carbon fibre rods composites developed by casting route. Carbon fibre rods of 4 mm and 6 mm diameters were surface sensitized to achieve electroless nickel coating followed by copper electroplating on the nickel coated rods and were used as the reinforcements to develop the composites. An air jet erosion rig made according to ASTM G76 standard configuration was used to conduct the tests. The effect of carbon fibre reinforcement, test duration and angle of impingement of the erodent on the erosion wear behaviour of the developed will be discussed at length.
