Preparation method of ZTA particle-reinforced steel matrix composite broken wall based on chemical method activating treatment

The invention discloses a preparation method of a ZTA particle-reinforced steel matrix composite broken wall based on chemical method activating treatment. The preparation method comprises the following steps: 1) ZTA particles are subjected to high temperature salt bath plating, and uniform titanium coatings are obtained on the surfaces of the ZTA particles; 2) nickel layers are formed at the peripheries of the titanium coatings; 3) the ZTA particles after plating are sintered, the ZTA particles are connected mutually to form a pore-shaped prefabricated body; and 4) the prefabricated body is fixed to a moulded end face or working face, then steel matrix material molten metal is cast by adopting a cast-infiltration technology, and after cooling, the ZTA particle-reinforced steel matrix composite broken wall is obtained. Active elements introduced in the preparation method can improve the interface boding property between the ZTA particles and metal, mechanical bonding between the ZTA particles and metal is changed to metallurgical bonding, and a macro bonding situation is shown in figure 1. The preparation method can improve the wear resistance of a composite, and ensures that the service life of the ZTA particle-reinforced steel matrix composite broken wall is long.
