“…also are capable for deposition of diamond and ten times faster than the hydrocarbons like methane and acetylene. Higher nucleation density is always desirable for a smooth and uniform diamond film [19][20][21]. Bias Enhanced Nucleation (BEN) is a very simple and preferable technique for nucleate more crystals.…”

Enormous developmental work has been made in synthesis of metastable diamond by hot filament chemical vapor deposition (HFCVD) method. In this paper, micro-crystalline diamond (MCD) was deposited on WC–6 wt.% Co cutting tool inserts by HFCVD technique. The MCD coated tool was characterized by the scanning electron microscope (SEM), X-ray diffraction (XRD) and micro Raman spectroscopy (μ-RS). A comparison was made among the MCD tool, uncoated tungsten carbide (WC) tool and polycrystalline diamond (PCD) tool during the dry turning of rolled aluminum. The various major tests were conducted such as surface roughness, cutting force and tool wear, which were taken into consideration to establish a proper comparison among the advanced cutting tools. Surface roughness was measured during machining by Talysurf. The tool wear was studied by SEM after machining. The cutting forces were measured by Kistler 3D-dynamometer during the machining process. The test results indicate that, the CVD coated MCD tool and PCD tool produced almost similar results. But, the price of PCD tools are five times costlier than MCD tools. So, MCD tool would be a better alternative for machining of aluminium.

The evolution of the tool materials from natural stone up to steel products, hard alloys, ceramics, superhard polycrystalline and crystalline materials is described. The necessity of transition to the new type of tool materials is shown. An idea of the effective processes of their processing with abrasive tools made of superhard materials is shown through the development results of the National Academy of Sciences of Ukraine. The book is intended for pupils, students, engineering and technical workers who are interested in the correct and effective use of tool materials for processing various products in everyday life and industrial conditions.
