1. , a kind of ultrasonic wave prepares the method for SiCp/AZ31 Mg-based nanocomposite, AZ31 magnesium alloy component content is Al 2.5%~

  • 3.0%, Mn 0.29%, Zn 0.70%~

    1.30%, and Si 0.08%, and Cu 0.03%, Fe 0.04%, surplus is Mg, it is characterized in that at first the nano SiC powder being joined carrying out the ultra-sonic dispersion pre-treatment in the ethanolic soln, then to the processing of drying, mill of pre-treatment mixing solutions;

    The AZ31 magnesium alloy is put into the crucible internal heating to fusing, and be incubated in 640~

    650 ℃

    of temperature ranges, horn is extend into below the bath surface, ultrasonic 5~

    10 minutes, ultrasonic power was 600~

    650W;

    The nano SiC powder that pre-treatment is good joins in the AZ31 magnesium alloy fused mass by mass percentage for the amount of 0.1-2.0% coats with masking foil, and identical ultrasonic power continued ultrasonic 15~

    20 minutes down, the casting sampling.
