Versatile Application of TiC inserts

Manganese steel has a high toughness, high ductility, high strain hardening capacity and an excellent wear resistance. This grade of steel is mostly used in the mining industry for crushing and loading equipment. we will introduce briefly why TiC inserts can be applied. Currently the challenge faced among others is the rate of work hardening, which is due to the crushing efficiency of the modern jaw and cone crushers. This limits the rate of work hardening produced on the surface of the metal thus resulting in low wear resistance, loss of material and cost of production for secondary and tertiary crushing equipment. Due to this challenge faced, researchers were motivated to come up with innovative ideas and new development that will increase the hardness and wear resistance of the said steel, resulting in longer service life of the components. These developments include the introduction of a new heat treatment procedure, the addition of micro alloying with Chromium and the use of metal matrix composite on manganese steel casting.

TiC carbide cermets and TiC-Fe/Fe bilayer composites consisting of a pure Fe layer and a TiC-Fe cermets layer were fabricated by hot-pressing sintering. The pure Fe layer contributes to the toughness of composites, and the TiC-Fe cermets layer endows the composites with an improved tensile strength and hardness. Steel-bonded titanium carbide (TiC) materials are manufactured by using advanced powder metallurgy technologies.
