The effect of a DLC coating adhesion layer on the corrosion behavior of titanium and the Ti6Al4V alloy for dental implants

Nanotribological response of a-C:H coated metallic biomaterials: the cases of stainless steel, titanium, and niobium

“…[31][32][33][34] They have concluded that the coating may contribute to a reduction in thrombogenicity by suppressing platelet adhesion and activation, and in inflammatory response by minimizing the release of cytotoxic metal ions. Additionally, a-C coating has been shown to improve the corrosion resistance behavior of titanium and Ti 6 Al 4 V alloys for dental implants, 24 as wells as to serve as a galvanic corrosion barrier between dental implant abutments and nickel-chromium superstructures. 35 Although numerous studies have indicated the excellent potential for a-C in biomedical applications, the findings have been variable in terms of material substrate, deposition method, and coating characteristics.…”

Surface damage mitigation of Ti6Al4V alloy via thermal oxidation for oil and gas exploitation application: characterization of the microstructure and evaluation of the surface performance

“…16 A variety of surface treatment technologies, such as thermochemical surface treatment, micro arc oxidation (MAO)/plasma electrolytic oxidation (PEO), physical vapor deposition (PVD), chemical vapor deposition (CVD), ion implantation, thermal spraying, thermal oxidation (TO), laser surface treatment and electrospark deposition (ESD), and several duplex treatments have been conducted to improve the surface performance of titanium and its alloys. [17][18][19][20][21][22][23][24][25][26][27][28][29][30] Among the mentioned surface treatment technologies, thermal oxidation (TO) is an ideal surface technique that has been industrially used to strengthen the Ti-based materials. 31 Its popularity is mainly assign to its cost effectiveness, simplicity and rapidity.…”

Influence of hydrogen incorporation and coating thickness on the corrosion resistance of carbon based coatings deposited by magnetron sputtering

“…Carbon is able to adopt different structures due to its different hybridization states (sp 1 Unfortunately, the human body represents a corrosive environment and, hence, the use of metallic implants results in the corrosive wear of these biodevices, causing the release of metal ions, which may be toxic to the human body and thus, compromise their biocompatibility [11]. In order to overcome this drawback, biocompatible and protective coatings, like DLC [11][12][13][14][15][16], transition metal nitrides [17], carbides [18] and carbonitrides [19] have been proposed. The electrochemical behavior of carbon based reported results indicate that these coatings are able to improve the corrosion resistance of different metals, owing to its inert chemical nature and low permeability [11-16, 20,21].…”

“…The electrochemical behavior of carbon based reported results indicate that these coatings are able to improve the corrosion resistance of different metals, owing to its inert chemical nature and low permeability [11-16, 20,21]. The reported works focus on the influence of adhesion interlayer [12, [15][16], coatings thickness [14], structure and morphology [20,21,22], as well as the incorporation of different metals, namely Ti and Cr on the carbon coatings electrochemical behavior [23]. and, lastly, the power of the graphite target was gradually increased from 0 up to 7.5 W/cm 2 , during 5 minutes [29].…”
