The invention belongs to the field of aluminum-based
composite material recycling, and particularly relates to an aluminum-based
composite material machining chip recycling method which comprises the steps that oil stains and floating dust on the surfaces of
machining chips are removed, and the
machining chips are crushed into sheets; carrying out alkali washing and
acid washing cleaning to remove an
oxide layer; determining a reinforced phase
mass fraction through
pickling; stirring the flaky material, and performing gravity
settling to obtain particles arranged in parallel; performing low-temperature
vacuum sintering to obtain a billet; and the aluminum-based
composite material with high
interface bonding strength and good uniformity is prepared through high-temperature plastic deformation. And the particle reinforced aluminum matrix composite material
processing chips are recycled, so that the machining loss is reduced. And the
oxide layer is removed, and the particle
sintering difficulty is reduced. And the
processing chips are arranged in parallel, so that the problems that the sheet-shaped aluminum-based composite material particles are not dense in
hot pressing and easy to generate pores due to high strength are solved, and a new scheme is provided for recycling and reusing the composite material.
