“…The precision-cut samples then underwent chemical pre-treatment, seeding and cleaning. The chemical treatments involved Murakami agent (10 g [K 3 Fe(CN) 6 ]þ 10 g KOHþ100 ml water) followed by acid etching with nitric acid (60% concentrate HNO 3 þ 30% H 2 O 2 at 1 to 9 parts) for different times. This treatment was used to ensure that the surface cobalt was reduced to o0.5%.…”

“…The main reason for this attention is that NCD films have a low surface roughness [1] while retaining bulk diamond mechanical properties and are used in a diverse array of applications from tribology [2] to machining [3], with advantages such as a low wear and friction coefficient [4] and a significant reduction in cutting forces [2] when used as coatings in applications such as machining [5], dental [6] and drilling [7]. NCD can be deposited using chemical vapor deposition techniques, mainly microwave plasma CVD [8,9] and hot filament chemical vapor deposition (HFCVD) [9][10][11].…”

This paper reviews the growth of diamond by chemical vapour deposition (CVD). It includes the following seven parts: (1) Properties of diamond: this part briefly introduces the unique properties of diamond and their origin and lists some of the most common diamond applications. (2) Growth of diamond by CVD: this part reviews the history and the methods of growing CVD diamond. (3) Mechanisms of CVD diamond growth: this part discusses the current understanding on the growth of metastable diamond from the vapour phase. (4) Characterization of CVD diamond: we discuss the two most common techniques, Raman and XRD, which have been intensively employed for characterizing CVD diamond. (5) CVD diamond growth characteristics: this part demonstrates the characteristics of diamond nucleation and growth on various types of substrate materials. (6) Nanocrystalline diamond: in this section, we present an introduction to the growth mechanisms of nanocrystalline diamond and discuss their Raman features. This paper provides necessary information for those who are starting to work in the field of CVD diamond, as well as for those who need a relatively complete picture of the growth of CVD diamond.

“…3,7,17 However, further research is needed to assess the performance of various drill bit materials because many researchers unveiled that drill bit material has an insignificant effect on the bone damage. 12,39,86,108,177 The coating method is another alternative to enhance the drill bit performance; Salguiredo et al 155 successfully lowered the drilling temperature (4°C) by using Diamond-Like-Carbon (DLC) coating and noted that the wear particles from DLC are not harmful to humans. Furthermore, Dorr et al 57 reported similar observations regarding the coating drill bit.…”

As drilling generates substantial bone thermomechanical damage due to inappropriate cutting tool selection, researchers have proposed various approaches to mitigate this problem. Among these, improving the drill bit design is one of the most feasible and economical solutions. The theory and applications in drill design have been progressing, and research has been published in various fields. However, pieces of information on drill design are dispersed, and no comprehensive review paper focusing on this topic. Systemizing this information is crucial and, therefore, the impetus of this review. Here, we review not only the state-of-the-art in drill bit designs-advances in surgical drill bit design-but also the influences of each drill bit geometries on bone damage. Also, this work provides future directions for this topic and guidelines for designing an improved surgical drill bit. The information in this paper would be useful as a onestop document for clinicians, engineers, and researchers who require information related to the tool design in bone drilling surgery.
