A cutting tool for machining titanium and titanium alloys which comprises a tungsten carbide-containing substrate alone or with a tungsten carbide tip brazed thereto. The cutting tool further includes a hard coating on either the substrate alone or on the tungsten carbide tip. The coating may be PVD-applied tungsten carbide, CVD-applied boron carbide or PVD-applied boron by: Titanium carbide (Tic) was chosen as the coating material because it is one of the more effective coatings on steel substrates (ref. 3). The alloys were titanium - 6-percent aluminum - 4-percent vanadium (Ti-6AV) and nickel - percent chrom- ium - percent cobalt - percent molybdenum - 3-percent titanium @en& 41).

Titanium Carbide is generally immediately available in most volumes. Ultra high purity, high purity, submicron and nanopowder forms may be considered. Carbides are compounds in which the anion is one or more carbon atoms. Most metals form carbide compounds, though not all: Indium and Gallium, for example, do not.

Prof Akinlabi shows a close-up of a titanium alloy grade 5 substrate, where laser additive manufacturing has deposited titanium carbide powder, which successfully enhanced the. Physical vapor deposition (PVD), sometimes (especially in single-crystal growth contexts) called physical vapor transport (PVT), describes a variety of vacuum deposition methods which can be used to produce thin films and coatings.
PVD is characterized by a process in which the material goes from a condensed phase to a vapor phase and then back to a thin film condensed phase. Titanium carbide, Ti C, is an extremely hard (Mohs 9–) refractory ceramic material, similar to tungsten has the appearance of black powder with the sodium chloride (face-centered cubic) crystal found in nature its crystals range in size from to mm.
It occurs in nature as a form of the very rare mineral Khamrabaevite (see Khamrabaevite, Russian Appearance: black powder.

Increasing substitution of with titanium nitride, titanium carbide, and numerous other coatings by physical vapor deposition technique for improved perfor- mance and increased tool life. High-speed steel - and. PVD stands for Physical Vapor Deposition.
PVD Coating refers to a variety of thin film deposition techniques where a solid material is vaporized in a vacuum environment and deposited on substrates as a pure material or alloy composition coating.
As the process transfers the coating material as a single atom or on the molecular level, it can. Other articles where Titanium carbide is discussed: titanium processing: Chemical compounds: Titanium carbide (TiC) is used extensively for cutting tools because of its combination of wear resistance and high hardness.
It is one of the hardest natural carbides. Titanium nitride (TiN) has an attractive yellow colour that is used in jewelry and decorative glass coatings.

Router bits made of steel are cheaper, but that is the only advantage. Carbide-tipped router bits maintain a sharper cutting edge longer than steel, produce a better finish when cutting, and provide cleaner and smoother cuts. They also withstand very high temperatures better than. Physical Vapor Deposition – also known as PVD Coating or Thin Film – refers to a variety of deposition techniques where solid metal vaporizes in a high vacuum environment.
Then it deposits on electrically conductive materials as a pure metal or alloy coating. The aim of the present work is to minimize the wear rate by nano-coating Boron Carbide (B4C) on the high speed steel (HSS) substrate.
For this purpose the B4C is being coated on the substrate using sputter deposition method and the wear rate is being analysed by performing pin-on-disc experiment on the coated and uncoated substrate to compare the wear rate on both substrate.
