“…The second generation was Co‐Cr‐based alloys, which are widely used in artificial hip and knee joints because of their wear resistance; however, the development of nickel‐free Co‐Cr‐based alloys is imperative for those with nickel allergies. Various routes such as ion implantion, surface coating, and doping are used to enhance the wear resistance, reduce the friction coefficient, and increase the hardness of Co‐Cr‐based alloys. The third generation is titanium‐based alloys, which are extensively studied and are used in implants in artificial bones because of its good biocompatibility, mechanical properties, and wear resistance .…”

Graphene oxide/poly(ethylene glycol) (GO/PEG) composites that have biocompatibility and biodegradability properties have been prepared to improve the lubrication of artificial joints, but they would be rapidly degraded and absorbed by the human body if injected. To prolong the lubrication effect, GO/PEG lubricants were mixed into a chitosan (CS) sol, and then the GO/PEG/CS sol was added to the dimpled texture of a Co‐Cr‐Mo alloy and transformed into a gel to slowly release GO/PEG lubricants. The results of friction experiments showed that the average friction coefficient of the slow‐release solution is below 0.025, especially when under pressure, and the gel in the texture also has a good lubrication effect. Meanwhile, the FTIR and UV–vis of the slow‐release solution indicated that it is likely to contain GO, PEG, and CS, which are associated with each other via hydrogen bonds and may form a particular structure, leading to good slow‐release lubrication. © 2017 Wiley Periodicals, Inc.

Tribological phenomena abundantly exist in living beings, especially in human beings, such as teeth, eyes, bones, skins, heart valves and so on, and it is of meanings to reveal the mechanism of tribology in human body and fabricate artificial biomaterials to replace the damaged tissues to release the pain of patients. Alloys, ceramics and polymers are three uppermost materials used in engineering and some of them play a crucial role in biomedicine. In the paper, we provide an overview of the tribological behaviors of artificial biomaterials including alloys, ceramics and polymers. We aim to provide fundamental mechanistic and applications of tribological biomaterials, while emphasizing the advantages and disadvantages of various kinds of tribological biomaterials. Finally, some challenges and the potential promising breakthroughs are also succinctly highlighted in this field.

“…However, in the case of deep-hole drills, precise dimensions in the processed parts pose certain limitations on surface engineering applicability. It was proved, however, that ion implantation is a method that does not impact on the shape of tools, but functionalizes the surface properties [ 21 ]. It is a relatively cheap method for tool improvement, in which the process temperature can be performed even below 100 °C [ 22 ].…”

Wear Resistance Improvement of Cemented Tungsten Carbide Deep-Hole Drills after Ion Implantation

et al. 2021

The paper is dedicated to the life prolongation of the tools designed for deep-hole drilling. Among available methods, an ion implantation process was used to improve the durability of tungsten carbide (WC)-Co guide pads. Nitrogen fluencies of 3 × 1017 cm−2, 4 × 1017 cm−2 and 5 × 1017 cm−2 were applied, and scanning electron microscope (SEM) observations, energy dispersive spectroscopy (EDS) analyses, X-ray photoelectron spectroscopy (XPS) and Secondary Ion Mass Spectrometry (SIMS) measurements were performed for both nonimplanted and implanted tools. The durability tests of nonimplanted and the modified tools were performed in industrial conditions. The durability of implanted guide pads was above 2.5 times greater than nonimplanted ones in the best case, presumably due to the presence of a carbon-rich layer and extremely hard tungsten nitrides. The achieved effect may be attributed to the dissociation of tungsten carbide phase and to the lubrication effect. The latter was due to the presence of pure carbon layer with a thickness of a few dozen nanometers. Notably, this layer was formed at a temperature of 200 °C, much smaller than in previously reported research, which makes the findings even more valuable from economic and environmental perspectives.
