“…Titanium and titanium alloy metals are commonly used in orthopedic and maxillofacial implants and devices, due to their relatively low density, lower Young's modulus, high strength and corrosion resistance in comparison to other metallic biomaterials. During the last three decades it was found that TiAl4V alloy is the most attractive type of Ti alloy for the dental and orthopedic implant applications, because of its better mechanical properties [1][2][3]. Although Ti6Al4V alloy has high corrosion resistance, and biocompatibility properties, it has certain limitations, such as the release of Al and V ions, which may cause allergic reactions in certain patients with metal sensitivity [1,2,4].…”

On the other hand, although much better than any other metallic alloy, Young's modulus of Ti6Al4V (~110 GPa) is much higher than Young's modulus of human bone (~25 GPa) which might lead to complications in the longterm [3,5].…”

“…The technological approach to increasing the load capacity of gearings includes various sophisticated technologies, including chemical and heat treatment methods [4]. The application of hard thin coatings on steel parts most often increases wear resistance [5] at higher temperatures [6], corrosion [7], as well as combined stress [8]. In particular, several technologies such as PVD, CVD, PACVD and others for the surface application of hard thin coatings have been used in the past few years with the development of material engineering to increase the load capacity of gearings.…”

This paper discusses the possibility of increasing the surface load capacity in C60E steel gearings by applying DLC thin coating. It describes the effect of tribological characteristics, such as friction coefficient, wear, adhesion and hardness of DLC coating on convex-concave gearing (C-C). The average thickness of DLC coating is 1.2 μm. Delamination of the DLC coating was recorded at a load of approximately 50 N. The friction coefficient of the DLC coating was 0.09. The nano-hardness of the DLC coating was 14.4 GPa. The results of the tests to scuffing on C-C gearings on the Niemann tester show that the DLC coating deposition occurred at load level 5. The complete removal of the coating was preceded by gradual thinning. After its removal, the wear continued substrate, where the traces after milling filled-up with the substrate metal.

“…[29][30][31][32][33] By using low-pressure plasma, surface carburizing can be obtained by applying a negative voltage on the substrate, which accelerates ions leading to their implantation. 25,[34][35][36][37] Particularly, such implantation is obtained with relatively low-energy hydrocarbon ions by applying low negative voltages, typically lower than 1 kV, thus leading to the rapid formation of a carbide layer while avoiding high temperatures. [35][36][37] In addition, using methane as gas allows both carburizing and DLC deposition to be achieved in a single stage by low-pressure plasma.…”

Diamond-like carbon (DLC) thin films constitute proven protective coatings due to their outstanding mechanical and tribological properties, combined with a relative chemical inertness and long-term stability. These make them particularly attractive to protect metallic medical implants from corrosion and erosion. However, lack of adhesion between DLC and metallic surfaces is a recurrent problem due to poor interactions with the native oxide layer. An effective strategy to overcome these adhesion issues consists in building interfacial layers. In this context, in this work, the use of a plasma treatment to generate shallow metallic carbide layers was investigated, to promote DLC adhesion directly on the surface of 316L stainless steel (SS).The metallic carbides presence stabilizes and promotes DLC thin film deposition. The highest adhesion was obtained on samples carburized by methane during 20 min with a bias of À700 V. Furthermore, this led to interface amorphization. In conclusion, this study shows that plasma can provide new insights for overcoming the lack of adhesion of DLC thin films on SS metallic surfaces.coating adhesion, depth profile analysis, diamond-like carbon, interface, plasma carburizing | INTRODUCTIONCarbon-based thin films have emerged as potent coatings for a number of applications thanks to the richness and versatility they offer in terms of chemistry and nanostructures. 1,2 In particular, the specific nanostructure of diamond-like carbon (DLC), a metastable form of amorphous carbon characterized by a significant amount of sp 3 bonds, directly confers valuable properties of diamond to the
