The formation mechanism, microstructure, mechanical properties and wear resistance of in-situ preparation of titanium carbide particles reinforced steel matrix composites were summarized. In-Situ Preparation of Titanium Dioxide Particles Reinforced steel matrix composites are based on the strong binding capacity of titanium and carbon while satisfying thermodynamic and kinetic conditions. The reinforced forms are mainly single homogeneous titanium carbide particles, surface gradient distribution of titanium carbide particles, titanium carbide particle beam and carbide total enhancement, etc., both with the composite area of high hardness, good wear resistance characteristics. Its future direction includes improving service life and reducing costs.
