Method for preparing metal glass coating by utilizing electrical sparkle deposition process

The invention relates to a method for preparing a metal glass coating by utilizing an electrical sparkle deposition process and belongs to the technical field of metal glass coating preparation. A metal A serves as an anode, an electric conductor where a metal A glass coating is pre-deposited serves as a cathode; in the preparation process, when the voltage is 50-60 V, the control capacitance is 40-200 [mu] F, the discharge frequency is 1000-2000 Hz, and the cooling velocity of an anode nickel base alloy deposited on the cathode is controlled to be 105-106 K/s; when the voltage is 61-99 V, the control capacitance is 20-39.9 [mu] F, the discharge frequency is 1000-2000 Hz, and the cooling velocity of a cathode nickel base alloy deposited on the cathode is controlled to be 105-106 K/s; when the voltage is 100-150 V, the control capacitance is 5-15 [mu] F, the discharge frequency is 1000-2000 Hz, and the cooling velocity of an anode nickel base alloy deposited on the cathode is controlled to be 105-106 K/s.
