The invention discloses a preparation method of a surface-modified ZTA
ceramic particle reinforced steel based
composite material. The preparation method comprises the steps that
sensitization and activation treatment is conducted on ZTA particles, surface plating is conducted, the ZTA particles are plated with
nickel and
chromium to achieve surface metallization by controlling the components andthe proportion of a plating solution, the ZTA particles plated with Cr-Ni
layers, Ni-Cr
alloy powder and
Al powder are put into a
graphite mold to be made into a preform which is of a
honeycomb structure through
vacuum sintering,
molten metal is poured by adopting a
casting infiltration method, and after cooling is conducted, the reinforced steel based
composite material is obtained. According tothe preparation method of the surface-modified ZTA
ceramic particle reinforced steel based
composite material, the ZTA particles are plated with
nickel and
chromium to achieve surface metallization bycontrolling the components and the proportion of the plating solution, the wet problem with a
metal matrix is solved, and then the
mechanical property of the composite material is improved; and meanwhile, the technology is easy to operate, the cost is reduced to a large extent, no
toxicity or
pollution is generated, the great potential on increasing the economic benefit and the social benefit isachieved, and the good prospect of being applied to the harsh
abrasive wear condition is achieved.
