WebHot filament chemical vapor deposition (HFCVD) diamond-coated small aperture wire-drawing dies from Φ 0. 8 to Φ 2 mm are in high demand. A new deposition technique without filaments through the inner hole of wire-drawing dies is proposed, accompanied with the specially designed fixtures. Web2. Experimental procedure. Boron doped diamond layers were grown on mosaic single-crystal diamond wafers, where the procedure to prepare them is described in our preceding works [Citation 9, Citation 23].Figure 1 shows schematics of the arrangement of the filament and the wafers, which are placed in a commercial HFCVD reactor (sp3 Diamond …

Diamond possesses excellent physical properties, such as high hardness, wide band, high thermal conductivity, negative electronic affinity, and strong corrosion resistance, so it has a wide range of applications in electronic devices used in high-temperature high-frequency field emission devices, electrochemical electrodes, and so on. WebKeywords: mechanical seals; diamond; HFCVD; multi-layer; adhesion; WC-Co; superficial pre-treatments; wear tests 1. Introduction The mechanical seal is a device developed on the late 1930s and the beginning of the 1940s. It allows the connection between systems or mechanisms with the purpose of reducing or eliminating fluid leaking.
