• Abstract:

  Titanium carbonitride (TiCN) is an ultra-high temperature ceramic (UHTC) material, widely used in cutting tools, semiconductor transistors and wear-resistant coatings. Its high hardness, excellent abrasion resistance, low coefficient of friction and chemical resistance at high temperatures make it a promising candidate to replace WC-Co carbide materials. However, the brittleness and low fracture toughness of pure TiCN limit its use, and it is more commonly used as a hard phase bonded to a metallic material to form wear-resistant composites. Pulsed plasma sintering (SPS) has excelled in achieving high densification in pure materials, due to its unique heating source, high heating rates and reduced sintering times. This minimizes defects caused by high temperatures and long processing times in traditional powder metallurgy. This article analyzed the state of the art on pure TiCN and TiCN with added binders, sintered via SPS. The studies indicated that SPS provides superior results, making it an effective alternative for manufacturing hard, wear-resistant materials.
