Reactions of Cr3C2-TiN system materials with nickel-chromium alloys
- 27 Downloads
Studies have been made on the kinetics of wetting and contact interaction for materials in the Cr3C2-TiN system with nickel-chromium alloys. The chromium in the Ni-Cr alloys is surface-active and reduces the surface tension and tends to reduce the wetting angle. The interaction zone has a heterophase structure, which is characterized by the presence of restricted solid solutions in the Cr3C2-Ni system. The Ni-Cr alloys have high adhesion activity for the composite material 50 mass% Cr7C3-TiN and constitute promising metal bonding agents for ceramic composites, which may have high levels of wear resistance and corrosion immunity.
