Embodiment 1
[0032] The preparation method of a kind of oxide ceramic particle reinforced Cu-based composite material according to the present invention adopts the technical scheme, and the specific method is:
[0033] Step 1. Select copper nitrate powder, ammonium metatungstate powder and aluminum nitrate (or zirconium nitrate) powder with a purity greater than 99.99% as raw materials, and calculate according to the weight ratio of Cu:W:Al2O3 (or ZrO2) controlled at 77:5:0.05 Get the required copper nitrate powder, ammonium metatungstate powder and aluminum nitrate (or zirconium nitrate) powder, and use a high-precision balance to weigh and set aside;
[0034] Step 2. Slowly add the aluminum nitrate (or zirconium nitrate), copper nitrate and ammonium metatungstate powders taken in step 1 into 3 beakers pre-added with deionized water, and the concentration is controlled at 1mol / L. Then put the beaker into the ultrasonic oscillator for ultrasonic vibration, and start the electric stirrer at...
