Problems solved by technology

[0004] However, the existing methods for the preparation of Ti(C,N)-based cermets toughened by silicon carbide particles generally have poor wettability between silicon carbide and Ti(C,N)-based cermets, and the two-phase interface is difficult to control, resulting in mechanical failure of composite materials. Low performance seriously restricts the application of composite materials; at the same time, due to the small size of silicon carbide particles, the surface activity of individual particles is large, and they are easily adsorbed to each other, which easily causes large-area agglomeration of silicon carbide particles, resulting in silicon carbide and Ti Inhomogeneous dispersion of (C,N)-based cermet materials reduces the mechanical properties of composites

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, and more specifically relates to a coated nano-silicon carbide whisker toughened Ti(C,N)-based cermet material and a preparation method thereof. Background technique [0002] Ti(C,N)-based cermets have the characteristics of high hardness, low density, chemical stability, good polishability, good oxidation resistance and excellent creep resistance, so they have attracted widespread attention at home and abroad. However, traditional Ti(C,N)-based cermets still have shortcomings such as insufficient toughness and strength, which severely limit their service life and application range. Therefore, how to improve the strength and toughness of Ti(C,N)-based cermets has become a concern of material researchers. [0003] The silicon carbide reinforced composite material has excellent mechanical and physical properties such as high specific strength and specific stiffness, wear resistance, fati...
