“…The counterface of the DLC‐coated femoral head is mostly a polymer acetabular cup made of ultrahigh molecular weight polyethylene (UHMWPE). In 1993, an attempt was made to study the adherence of a‐C:H or nitrogen incorporated a‐C films on joint prosthesis materials like metals, ceramics, and polymers by means of scratch hardness testing 56. Some extensive studies were carried out on wear reduction effects of Co‐Cr, alumina, and a‐C:H coated Co‐Cr with metal adhesion layer against UHMWPE by a special knee wear simulator 57.…”

Owing to its superior tribological and mechanical properties with corrosion resistance, biocompatibility, and hemocompatibility, diamond-like carbon (DLC) has emerged as a promising material for biomedical applications. DLC films with various atomic bond structures and compositions are finding places in orthopedic, cardiovascular, and dental applications. Cells grew on to DLC coating without any cytotoxity and inflammation. DLC coatings in orthopedic applications reduced wear, corrosion, and debris formation. DLC coating also reduced thrombogenicity by minimizing the platelet adhesion and activation. However, some contradictory results (Airoldi et al., Am J Cardiol 2004;93:474-477, Taeger et al., Mat-wiss u Werkstofftech 2003;34:1094-1100) were also reported that no significant improvement was observed in the performance of DLC-coated stainless stent or DLC-coated femoral head. This controversy should be discussed based on the detailed information of the coating such as atomic bond structure, composition, and/or electronic structure. In addition, instability of the DLC coating caused by its high level of residual stress and poor adhesion in aqueous environment should be carefully considered. Further in vitro and in vivo studies are thus required to confirm its use for medical devices. '

“…However, its adhesion to some recognized biomedical substrate materials, such as titanium and CoCr, is limited 3 and, in many instances, interlayers are used to improve adhesion. 4,5 For the deposition of adherent DLC onto titanium, one of the more promising approaches involves TiN and TiC interlayers, to give a Ti-TiN-TiC-DLC multilayer structure.…”

“…6,7 The deposition of DLC, on a wide range of substrate materials, has received considerable attention in the literature. Favorable results have been reported for applications such as surgical needles for corneal surgery, 8 materials for total joint replacement, 3,9 orthopedic pins and screws, 10 dental prostheses, 11 medical guidewires, 12 heart valve replacements, 13 and rotary pumps for left ventricular assistance. 14 The use of TiN for dental prostheses [15][16][17][18] and for hip joint and heart valve replacements 19,20 has also been reported.…”

The hemocompatibility of a TiN/TiC/diamond-like carbon (DLC) multilayer structure, deposited on titanium substrates for use as coatings for a heart valve prosthesis, has been studied through the adsorption of blood proteins and the adhesion and attachment of blood platelets. All of the surfaces were characterized by stylus profilometry and water contact angles. The adsorption of albumin and fibrinogen to the surfaces was assessed using the Amido Black assay, whereas platelet attachment was studied by scanning electron microscopy and quantified using stereological techniques. The degree of platelet spreading on the surfaces was seen to correlate with differences in surface energy, indicated from contact angle measurements. The greatest spreading was seen on the more hydrophilic surfaces. When studying protein adsorption to the surfaces, no correlation could be determined between contact angle results and levels of adsorption, although the most hydrophilic surfaces did appear to promote greater amounts of fibrinogen adsorption. Thrombus formation was observed to some degree on all of the surfaces, with the exception of the DLC coating. This coating also promoted less spreading of platelets than the other surfaces. The good hemocompatibility of the DLC coating is attributed to its hydrophobicity and smooth surface, resulting in a higher ratio of albumin to fibrinogen than any of the other surfaces.

“…This is due to the combination of low interaction with the native oxide layers and intrinsic DLC residual stresses, leading to the delamination of the DLC film. 6,[13][14][15][16] Two main approaches have been proposed to overcome delamination. The first approach consists in reducing the film intrinsic residual compressive stress.…”

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
