Nitride, Zirconia, Alumina, and Carbide Coatings on Ti6Al4V Femoral Heads: Effect of Deposition Techniques on Mechanical and Tribological Properties

Abstract

Ti6Al4V has been extensively studied in orthopedic applications because of its biocompatibility, desirable mechanical strength, and fatigue resistance. A wide range of bioinert ceramics have been investigated to further develop the tribological and mechanical properties of Ti6Al4V for the production of potential femoral heads. However, an analysis of the literature indicates that the performance of the coatings produced has been inconsistent. In this review, for the first-time deposition techniques of the most widely studied bioinert ceramics namely nitrides, carbides, zirconia, and alumina on Ti6Al4V substrates and their relevant mechanical and tribological performance have been analyzed. Finally, graphene has also been suggested for use together with bioinert ceramics due to its excellent mechanical and physical properties for coating Ti6Al4V femoral heads.

Exploring the effect of chlorhexidine concentration on the biocorrosion behavior of Ti6Al4V for dental implants

“…Therefore, it results in implant loss because of reducing the implant strength, increasing the healing time, infection and inflammation at the surgical site, and toxicity. Releasing metal ions can cause the discoloration of the surrounding soft tissue, allergic reactions, and rash in some patients (Ege et al, 2017). Also, the broken corrosion products lead to the inflammation of the surrounding tissues.…”

“…Among titanium alloys, the Ti6Al4V alloy demonstrates unique properties, such as excellent mechanical behaviors (high strength and high fatigue resistance), chemical neutrality, and low modulus close to that of the bone. This alloy also has excellent biological properties, such as superior biocompatibility, light‐weight and increased osteoconductivity (Ege et al, 2017; Pushp et al, 2022).…”

Influence of surface coatings on the stress distribution by varying friction contact at implant-bone interface using finite element analysis

“…Titanium Nitride (TiN) coatings have displayed exceptional tribo-mechanical properties while also improving the biocompatibility of the implant. 29,30 Studies have shown that Zirconium Nitride (ZrN) coatings have improved corrosion resistance, along with excellent biocompatibility and chemical stability. 31,32 Titanium Oxide (TiO 2 ) coatings have been shown to enhance the wear resistance along with cultivating the biocompatibility of titanium implants.…”

“…After analysing the research done to study the tribological performance of the various surface coatings applied on the titanium implant, three commonly used surface coatings (Figure 1) were selected for this study, and the average friction coefficient values obtained were chosen. The mean value of the friction coefficient (m) obtained for titanium nitride coatings is 0.19 29,30 ; for zirconium nitride coatings is 0.49 31,32 and for titanium oxide coatings is 0.30. 33,34 The present study compares the effect of various surface coatings and implant designs of titanium dental implants using numerical methods.…”

Development and tribo-mechanical properties of functional ternary nitride coatings: Applications-based comprehensive review

“…Ceramic coatings of binary nitrides and carbides have been widely employed for these purposes as they have high hardness, better wear, and corrosion resistance. 178,179 Recently, the addition of soft metals like Cu into the TiN coatings has gained much popularity due to lower COF and relatively better ductility, corrosion, and wear resistance in TiCuN coating. 180 TiCuN coating can be prepared by many PVD techniques like magnetron sputtering, arc ion plating, and hollow cathode electron beam.…”
