  • Composite hard-surface material and preparation method therefor
    Patent number: 10166636
    Abstract: A composite hard-surface material preparation method and a composite hard-surface material prepared thereby, the preparation method comprising: dispersedly fixing a plurality of cemented carbide sheets (2) to a surface of a metal substrate (1); and surfacing the cemented carbide sheets (2) and the metal substrate (1) with a solder (3) to obtain a composite hard-surface material, the solder (3) comprising nickel-based alloy powder, tungsten carbide particles and boron nitride powder. The solder (3) used in the preparation of the composite hard-surface material comprises nickel-based alloy powder, tungsten carbide particles and boron nitride powder, wherein the nickel-based alloy powder can increase fluidity and corrosion resistance, the tungsten carbide particle can improve hardness, and the boron nitride powder can effectively reduce friction coefficient.
