Hardness diamond-like carbon

Microwear tests performed using atomic force microscopy (AFM) were reported by Miyake et al. [74] and by Schiitze [55]. The result was that the wear caused by a diamond tip is much greater for hBN than for cBN. The microwear rates of sputter deposited cBN films were found to be nearly the same as that of hard diamond like carbon films [55].

Plasma Synthesis The use of plasma methods has lead to a new range of materials having unique properties. An example is the family of amorphous elemental hydrides (eg cr-C H Of -Si H or-P H) which contain a variable proportion of H from almost zero to 50 atomic %. The carbon films, known variously as "hard carbon", "diamond-like carbon", " a-carbon" etc (9 ) - These layers are of considerable interest because of their optical and abrasion-resistant properties etc (Table I). The properties of these Gr-carbon films, can be tailored by modifying the plasma parameters. 

In this chapter, we explain why hydrothermal synthesis deserves special consideration and present a review of the current state of the art in hydrothermal synthesis of diamond as a potential future method of making diamond or hard diamond-like sp -carbon. 

Volume 1 starts with an introduction into novel ultra hard ceramics including diamond and diamond-like carbon, carbon nitrides and silicon nitrides as well as boron containing carbides, nitrides and carbonitrides. Here we wish to recognize the great fundamental and technological challenge of developing new superhard... 

In Volume 2 ceramic hard materials are highlighted in the light of their applications. Chapter 1 of Part III concisely reviews the history of diamond and diamondlike super abrasive tools while Chapter 2 and 3 are concerned with the application of chemical vapor deposited diamond and diamond-like carbon films. These sections...
