Due to many advantages and other valuable properties, synthetized diamonds have application in different areas, especially in medicine and electronics. Standard method which is used in the process is chemical vapor deposition or CVD. However, using conventional chemical vapor deposition leads to forming diamond films which consist of grains of micrometric size. It leads to the problem of high surface roughness and lower strength at break then it is expected, which significantly reduces the possibilities of application. This problem is solved by developing new nanocrystalline (NCD) diamond and ultra-nanocrystalline (UNCD) diamond materials which have exceptional mechanical properties and excellent tribological properties. The different structural properties are result of different conditions during producing process. While NCD is grown from hydrogen rich plasmas, the UNCD is grown from hydrogen poor plasmas. The plasmas used for grown could be used for characterized by optical emission spectroscopy and wavelength pyrometry. In this paper, the goal was to obtain relation between consolidation of diamonds and microstructures.
