The titanium carbide-based Cermet is a heterogeneous composite made up of alloys and metals. The high strength and hardness of the ceramic combine with high oxidation resistance, wear resistance, high temperature resistance, oxidation resistance, chemical stability, and high durability. Many synthetic methods for producing titanium carbide-based ceramics are available. Each has its benefits and limitations. You can choose the right process for your application and budget. 1. Chemical Vapor Deposition (CVD) It is a method that uses a space gas phase chemical reaction to deposit a thick thin film coating onto a substrate. Since the whole reaction is thermodynamic, CVD films have the benefits of high adhesion and coatingability as well as dense film layers and strong film-base bonding. These properties can allow for the creation of non-limiting TiC, such TiN, TiCN or TiBN coatings. However, this process has one drawback: The processing temperature can be quite high at 900 to 1200 degrees Celsius. This high heat causes the steel matrix of to become softened. The steel matrix must then be vacuum-cooled again after being processed. It is more difficult and can also be deformed easily, which results in a decrease in the strength of the matrix material. There will be a reduction in the amount of useful waste liquid and gas produced by the process. This can easily cause industrial pollution and is counter to green industries that are being promoted and used. 2. Physical vapor deposition (PVD) The substrate’s surface is coated using this technique. It uses physical processes, such as thermal, sputtering and glow discharge. These include sputtering, evaporation and ion-coating technology. These are the most commonly used PVD techniques for ceramic coating preparation. Because of its fragility, PVD films often have residual compressive stress. This film is not suitable for linear processing. It has low adhesion and poor coating properties. It is necessary for the workpiece to be able to swing or rotate during processing. This increases both the difficulty of designing and the difficulty of using the vacuum chamber. Probleme such as an ineffective coating. 3. Liquid deposition This is a chemical film-forming process that uses a wet chemical method. This method works on the principle of hydrolysis equilibrium movement. It does this by ligand replacing the ions in the solution. Once the solution has dissolved, the metal compounds are deposited onto the substrate. The operation of this method is very simple and doesn’t require heat treatment. However, this isn’t the best method because the reaction is in an aqueous solution. This means that the concentrations of the solutions are inconsistent between before and after deposition. Additionally, there are numerous influencing factors which can cause the liquid phase to react. 4. Thermal spraying It involves heating certain powdered or linear materials to a semi-melted or molten state using heat sources such as flame, plasma or arc. The droplets are then accelerated to form high-speed droplets that can be sprayed onto the substrate to create a protective coating. This can improve or renew the material’s surface properties, serve a protective function, and reduce wear due to corrosion or changes in processing tolerances. It can also be done using flame spraying and arc spraying. 5. In-situ Synthesis In-situ synthesis is where the second phase of the material or the reinforcing layer in composite materials is created during its formation. This means it does not exist before the preparation of the material. 6. You can also use other synthetic methods These preparations include in-situ and indirect synthesis processes as well as melting and casting, powder metallurgy, mechanical alloying and methods for high-density electron beam coating, hot-propagating high temperature synthesis and high-density energy beam cladding. Actual industrial production situations will dictate the choice of preparation methods for the carbonized-based Cermet composite material. TRUNNANO is also known as. Lempotee Nano Technology Co. Ltd.
