A nanocrystalline diamond bilayer has been deposited via hot filament chemical vapour deposition method. The bilayer has been produced by two different deposition parameters. The first is by limiting microcrystalline diamond growth and the second layer by pulsing additional oxygen gas into the system. The two layers become indistinguishable after the deposition ends. The pretreatment of the substrate, tungsten carbide has been varied i.e. its various seeding sizes (<0.1 μm synthetic, <0.5 μm synthetic, <0.25 μm natural, <0.5 μm natural, and <1 μm natural); with and without hammering by silicon carbide. This set up is highly similar to that of previous work however the different deposition time has caused the microcrystalline diamond layer to be nanocrystalline diamond instead. Results presented are the optical and SEM (up to 100,000x magnification) images of both planar and cross-section of the diamond layer. AFM gave topographical analysis of the diamond layer. The results show that the thickness is about 1.7 μm, top layer diamond about 100 nm in size and are indeed diamonds by XRD and Raman.

The performance of Atomic Force Microscope (AFM) is greatly determined by the quality of its probe. Nowadays, probes of diamond tips have become more and more popular than silicon ones, and have been widely used in industries. In this paper, research about the fabricating of nanocrystalline diamond (NCD) coated AFM probe has been done using Hot-Filament Chemical Vapour Deposition (HFCVD) technique. The results showed that NCD films have been grown on the probe. Problems about the growth of NCD on the tips have been discussed. The optimum parameters have also been proposed. This research can provide reference for the further experiments on the fabrication of NCD coated tips.

HFACVD (Hot Filament Assisted Chemical Vapour Deposition) is a typical technology which permits the coating of soft materials with hard or super hard layers which lead to ultra wear resistant tools. Typical tools obtained with this technology are based on a diamond layer. Unfortunately, these tools are not suitable for machining of ferrous alloys due to chemical issues, yet their use is very promising in the machining of composites based on aluminium matrix and reinforced with alumina or silicon carbide. In this paper HFACVD diamond coated, WC and PCD tools are used in turning of Al2O3/Al composites until they are completely worn out. The results show that the diamond tools can be competitive with both the WC and PCD ones in the industrial applications.
