Recently, practical applications of a hydrogen-containing amorphous carbon (a-C:H) films prepared by plasma chemical vapor deposition (CVD) method have been developed. Diamond-like carbon (DLC) films are currently used in medical devices as biocompatible and antithrombotic thin films. The bone/dental implant interface is a vital factor for the clinical success of osseointegration defined as a direct structural and functional connection [1, 2]. Titanium (Ti) has excellent physical properties and is the main material for dental and orthopedic implants as it is well-suited for easy osseointegration acquisition [3]. Modification of Ti surface properties and technological development are widely used to achieve a shorter period of osseointegration acquisition and successful strong osseointegration [3]. However, adhesion to the bone is insufficient and the durability of commercial dental implants is very low, necessitating fixing after approximately six months. Thus, an improvement in the surface of the dental implant material is required to achieve high durability and high bone-compatibility. In a previous study, we reported that bone compatibility improves by increasing the hydrogen content in DLC films. Therefore, hydrogenated DLC films fabricated using the plasma CVD method and the magnetron sputtering method that enable easy doping of hydrogen have been studied as surface treatment methods for bone tailoring [4-6].Because a-C:H prepared by the CVD method are not sufficiently hard, low durability is a serious problem. Therefore, the purpose of this study is to improve the durability and bone-compatibility of DLC films for use in dental implants. We first attempted to make hydrogen-containing tetrahedral amorphous carbon (ta-C:H) by cathodic arc ion-plating (CA) method using a graphite solid and a CH4 gas as a source for the DLC film; this approach has not been reported yet. Second, we investigated the CH4 gas flow ratio dependence of the current–voltage characteristics during the ta-C:H formation, as well as the structure and properties of the films.
