1. a kind of C/C composite material nanometer sic-sio2The preparation method of coating it is characterised in that:

  • comprise the following steps;

    1) nanometer sic powder body and 10~

    50ml Ludox are mixed with 1000~

    1500ml water, obtain mixture;

    2) it is stirred after mixture ultrasonic vibration, until nanometer silicon carbide and Ludox are uniformly dispersed, obtain nanometer sic denseSpend the suspension for 4~

    15g/l;

    3) the carbon/carbon compound material sample with sic coating is placed in the heating coil of electromagnetic induction heating instrument, then utilizesWater pump makes suspension circulate;

    4) suspension is opened electromagnetic induction heating instrument and is carried out electromagnetic induction using heating coil to sample after starting the cycle over flowingHeating, carries out continuous erosion using the suspension circulating to sample during electromagnetic induction heating, electromagnetic induction heatingCondition is;

    heat time heating time controls in 15~

    45min, and current intensity controls in 350~

    550a;

    After electromagnetic induction heating terminatesMake suspension stop washing away sample, naturally cool to after sample and after room temperature, sample is dried.
