“…Thus, enhancing the thermal stability, electrical conductivity and thermal conductivity of DLCs used for HFEK is important; the former can improve the graphitization resistance at elevated temperatures, and the latter can reduce the actual local temperature during operation. The author's team has prepared a DLC coating with a resistivity lower than 10 −4 Ω•cm by doping N and controlling hydrogen, and its conductivity is much higher than that of stainless steel, and slightly higher than that of graphite [113]. Furthermore, increasing the sp 3 C fraction and the content of metal-carbide compound nanoparticles with a high melting point in DLCs is also likely to be important [114][115][116].…”

Repairment and replacement of organs and tissues are part of the history of struggle against human diseases, in addition to the research and development (R&D) of drugs. Acquisition and processing of specific substances and physiological signals are very important to understand the effects of pathology and treatment. These depend on the available biomedical materials. The family of diamond-like carbon coatings (DLCs) has been extensively applied in many industrial fields. DLCs have also been demonstrated to be biocompatible, both in vivo and in vitro. In many cases, the performance of biomedical devices can be effectively enhanced by coating them with DLCs, such as vascular stents, prosthetic heart valves and surgical instruments. However, the feasibility of the application of DLC in biomedicine remains under discussion. This review introduces the current state of research and application of DLCs in biomedical devices, their potential application in biosensors and urgent problems to be solved. It will be useful to build a bridge between DLC R&D workers and biomedical workers in order to develop high-performance DLC films/coatings, promote their practical use and develop their potential applications in the biomedical field.

“…To suppress the effect of Co, the removal of Co of surfaces of WC-Co substrates by chemical etching, nitriding, or boriding has been applied. [21][22][23][24] However, the removal of Co can result in a decrease in the fracture strength of the samples 25) and should be avoided if possible.…”

In this study, the possibility of the disappearance of Co particles on the surface of nanocrystalline diamond (NCD) films having large thickness was examined. It is shown that the number of Co particles decreased clearly with the larger thickness. In the thickest case, the Co particles disappeared almost completely. Investigation with energy-dispersive spectroscopy for the cross section of the NCD films suggested that the Co particle was embedded during the growth of the NCD film. Our observations will contribute to deposit smooth NCD films on tools without the embrittlement of substrates by Co etching.
