“…The peaks at 583.50 eV (Cr 2p 1/2 ) and 574.30 eV (Cr 2p 3/2 ) were assigned to Cr [ 5 , 17 ] ( Figure 8 b). The Ag 3d XPS spectrum of the CrAgCeN coating displayed characteristic peaks at a bonding energy of 368.3 eV, which perfectly agrees with the literature value (368.2 eV) [ 42 ] ( Figure 8 d; recall also Section 3 and Figure 3 ). Meanwhile, a small amount of Ce was detected on the worn surfaces ( Figure 8 c).…”

“…The Ag 3d spectrum of CrAgCeN shows a characteristic peak at a bonding energy of 368.3 eV, consistent with literature reports (368.2 eV). Another characteristic peak at 367.5 eV in the Ag 3d spectrum [ 42 ] corresponds to AgN 3+ in CrAgCeN. The AgN 3+ spectra of CrN/Ag coatings are almost absent in the literature, possibly because when the Ce element is lacking, the kinetics are insufficient for AgN 3 formation.…”

This study investigates the effect of deposition pressure on the microstructure and tribological properties of CrAgCeN coatings synthesized via unbalanced magnetron sputtering. The CrAgCeN coatings presented a face-centered cubic structure. As the deposition pressure increased, the surface grain topography of the CrAgCeN coatings transformed from a looser pyramidal structure to a denser structure, while their hardness H and elastic modulus E first increased and then decreased. The strengthening effect was mainly attributable to Ag and Ce elements. Conversely, the coefficient of friction (COF) and wear rates of the coatings reduced and then increased. Under 0.6-Pa deposition pressure, the COF and wear rate of the CrAgCeN coating were minimized (0.391 and 3.2 × 10−7 mm3/(N·m), respectively) while the H and E were maximized (14.2 and 206.2 GPa, respectively). The values of hardness, wear resistance, resistance of elastic strain to failure (H/E) and resistance to plastic deformation (H3/E2) were improved for the coatings by Ce. The wear mechanisms were adhesion and delamination. The wear mechanisms were adhesion and delamination. Selecting the appropriate deposition pressure can improve the tribological properties of the CrAgCeN coatings. The received results of research in this study allow us to establish a rational coating composition for deposition on tools providing an increase in machining efficiency of the materials used in engineering. CrAgCeN coating with excellent properties may be applied to steel substrate through the combined action of corrosion, high temperature and mechanics.

“…Compared to other methods, the PIII is highly reliable and reproducible [ 43 ] and is able to dope various elements, including Ag [ 43 ], Ca [ 44 ], Mg [ 45 ] and Zn [ 46 ] into Ti implants. More importantly, the amount of the dopants can be easily controlled by adjusting the plasma time, pressure, pulse duration and pulse frequency during the injection process [ 47 ], which provides a convenient and feasible way to tune the surface property.…”

Titanium (Ti) and its alloys have been extensively used as implant materials in clinical practice due to their high corrosion resistance, light weight and excellent biocompatibility. However, the insufficient intrinsic osteogenic capacity of Ti and its alloys impedes bone repair and regeneration, and implant-related infection or inflammation remains the leading cause of implant failure. Bacterial infections or inflammatory diseases constitute severe threats to human health. The physicochemical properties of the material are critical to the success of clinical procedures, and the doping of Cu into Ti implants has been confirmed to be capable of enhancing the bone repair/regeneration, angiogenesis and antibacterial capability. This review outlines the recent advances in the design and preparation of Cu-doped Ti and Ti alloy implants, with a special focus on various methods, including plasma immersion implantation, magnetron sputtering, galvanic deposition, microarc oxidation and sol-gel synthesis. More importantly, the antibacterial and mechanical properties as well as the corrosion resistance and biocompatibility of Cu-doped Ti implants from different methods are systematically reviewed, and their prospects and limitations are also discussed.

“…Despite having outstanding mechanical and static corrosion properties, the tribocorrosion characteristics of Ti-alloys are poor exhibiting high levels of tribo-corrosive wear, seizure and gall when in contact with other surfaces [10]. Long-term release of toxic substances (Al and V ions) is another strong concern about using Ti-6Al-4V alloy as body implant material [11].…”
