“…In order to address these issues, high quality of lubrication is required for materials to work under harsh conditions involving high pressure and temperatures. In such cases CNTs have emerged as potential lubricants due to their lubricating, chemical and anti-wear properties [12][13][14].…”

Carbon nanotubes have emerged as potential reinforcement material for metallic matrices since their discovery in 1991 by Japanese scientist Sumo Iijima. It is observed that carbon nanotubes were comprised of multifunctional properties and were ideal reinforcement material for metallic matrices. In the present work we report the development of carbon nanotubes with multi-walls reinforced commercial purity copper nanocomposites. The carbon nanotubes content was varied from 0.25 to 1.0 wt% in the copper matrix nanocomposites. Here, carbon nanotubes were also nickel coated for improving the interfacial bonding with the copper matrix. In order to obtain the good dispersion of carbon nanotubes in the copper matrix, both materials were subjected to ultrasonication and blending process using ball milling. Further sintered nanocomposites were subjected to upsetting forging process, which involves densification and shape change simultaneously. Microstructure studies were conducted using scanning and transmission electron microscopes to study the dispersion of carbon nanotubes. The effect of carbon nanotubes on the mechanical properties like microhardness and tensile strength of copper matrix nanocomposites is studied in detail.

“…In recent years, adding self-lubricating particles to plating solutions seems to have become an effective method to further reduce the friction coefficient of coatings. It is reported that the applying of multi-walled carbon nanotubes reduces the friction coefficient and wear loss of Copper-Tin alloy to 28% and 32%, respectively [6]. That aside, as a potential lubricating material, polytetrafluoroethylene (PTFE) is usually adapted to modify compositing coatings.…”

The aim of this paper is to obtain Cu–Sn composite coatings incorporated with PTFE and TiO2 particles, which have superior antiwear and friction reduction properties. Electrodeposition was carried out in a pyrophosphate electrolyte, and the electrochemical behavior of the plating solutions was estimated. PTFE emulsion and TiO2 sol were prepared and used, of which the average particle sizes were less than 283 and 158 nm, respectively. Then, four different types of coatings, Cu–Sn, Cu–Sn–TiO2, Cu–Sn–PTFE and Cu–Sn–PTFE–TiO2, were electroplated with a pulsed power supply. Their microstructure, composition, microhardness, corrosion resistance and tribological properties were then analyzed and compared in detail. The results show that both PTFE and TiO2 are able to improve coating structure and corrosion resistance, while they have different effects on hardness and tribological properties. However, the presence of both PTFE and TiO2 in the deposited coating leads to a lower friction coefficient of 0.1 and higher wear and corrosion resistance.

“…An effective method of improving the friction and wear behavior of 20CrMnTi is to prepare 20CrMnTi-based selflubricating composites containing solid lubricants, such as graphene, [12][13][14] carbon nanotubes (CNTs), 15,16 and silver. 17,18 Zhai et al 12 explored the mechanical and tribological behaviors of a Ni 3 Al-multilayer graphene composite.…”
