Co-depositing of nickel (Ni) and nitrogen (N2) in the diamond-like carbon (DLC) matrix was synthesized by pulsed laser deposition (PLD) technique. In work presented here, N2 injected as a reactive gas to optimize optical, structural properties Ni:N-DLC thin films, although argon (Ar) ratio kept constant. Statistical films were calculated from surface topographic images 2Ni:N-DLC, 3Ni:N-DLC, 4Ni...

This paper comparatively studies the tribological behaviour of different types of diamond-like carbon (DLC) coatings in a reciprocating sliding wear test. The results are interpreted in terms of structure and surface morphological characteristics. At the beginning of each reciprocating sliding wear test, the higher coefficient of friction of the DLC coatings reflects the original surface condit...

Diamond Like Carbon (DLC) films were deposited on quartz substrates using Dense Plasma Focus (DPF) method. The formation of sp bonds as is it’s content in the film strongly depends on the substrate and it seems quartz is not a suitable substrate. However, we report here the formation of DLC films on quartz substrates that were maintained at elevated temperatures and show the content of carbon a...

There are numerous types of surface coatings available to engineers in order to improve the friction and wear resistance of components. In order to successfully use these coatings in practice, it is important to understand the different types of coatings available, and the factors that control their mechanical and tribological properties. This paper will focus on the application of diamond-like...

Diamond-like carbon (DLC) films are fabricated on the NiTi alloys at room temperature using plasma immersion ion implantation and deposition (PIIID). The effects of the substrate bias on the characteristics of the DLC films are systematically examined to correlate to the blood compatibility. The results show both the ID=IG ratio (inverse trend in the sp =sp ratio) and the G peak position first ...

Abstract Silica scale adhesion onto geothermal power plant equipment reduces the efficiency. In our previous study, diamond-like carbon (DLC) coatings with low sp 2 fractions and high hydrogen contents were found to suppress silica adhesion. Therefore, present study was aimed at clarifying mechanism of graphene-like network DLC. In-lens scanning electron microscopic imaging adhered defective gr...

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 an...

Diamond like carbon (DLC) films were deposited on Si and then patterned to form 40 nm features as nanoimprint templates. A plasma enhanced chemical vapor deposition (PECVD) system with CH4 precursor was used to deposit DLC films on Si and quartz substrates. These films were then characterized using Raman spectroscopy, atomic force microscopy (AFM), nanoindentation, and contact angle measurement...

Ultra-thin diamond-like carbon (DLC) coatings are used in hard disk drives to protect the intricate magnetic structures from wear and corrosion. The coating on the recording head consists of a hard DLC layer and a silicon (Si) layer that improves adhesion between the DLC layer and the substrate. Damage to this protective coating can expose the magnetic structures to corrosion and compromise the...

The interaction between resist and template during the separation process after nanoimprint lithography (NIL) can cause the formation of defects and damage to the templates and resist patterns. To alleviate these problems, fluorinated self-assembled monolayers (F-SAMs, i.e. tridecafluoro-1,1,2,2,tetrahydrooctyl trichlorosilane or FDTS) have been employed as template release coatings. However, w...
