Applications
- Wear surface (wear resistant) parts and coatings. Parts and coatings that undergo fretting, abrasion, cavitation, and particle erosion such as cyclones, fan blades, turbine blades, liners, chutes, hoppers and feeders.
- Corrosion resistant coatings. Tantalum carbide is used as a coating for parts requiring corrosion resistance such as vessels, piping, valves, and turbine blades.
- Mould coatings. Steel moulds used for aluminum alloys are coated in tantalum carbide to provide a wear resistant surface with a low coefficient of friction mould surface.
- Additives. Tantalum carbide powder is added to tungsten carbide/cobalt (WC/Co) to inhibit grain growth and increase hardness of the sintered structure.
Fabrication Methods
- Thermal Spray Process - High Velocity Oxygen Fuel (HVOF). Tantalum carbide powders are thermal sprayed to form hardface coatings on surfaces requiring increased wear resistance.
- Powder Metallurgical (P/M). Tantalum carbide powders are pressed into parts through hot or cold pressing and sintering.
