preparation example Construction

[0019] The invention provides a method for preparing a zirconium-based amorphous alloy composite material, which adopts a new plasma oxidation method to form a ceramic film layer with good performance on the surface of a zirconium-based amorphous alloy substrate; this electrochemical method is different from the existing Some micro-arc oxidation methods are embodied in the electrolyte system and power supply equipment: one, what the existing micro-arc oxidation uses is an alkaline electrolyte system, and what the plasma oxidation method provided by the present invention uses is a neutral electrolytic solution Liquid system, the ceramic film layer is formed in the neutral electrolyte system; 2. The electrolyte temperature of the existing micro-arc oxidation is low, and a water cooling system is required to control the temperature of the electrolyte at a certain level when preparing the micro-arc oxidation film. within the temperature range; and the electrolyte used in the plasma...

Embodiment 1

[0035] This Example 1 is used to illustrate the zirconium-based amorphous alloy composite material provided by the present invention and its preparation method. The preparation method of the zirconium-based amorphous alloy composite material includes the following steps:

[0036] Step 1. Preprocessing

[0037] The pretreated zirconium-based amorphous alloy substrate is a strip-shaped Zr of 80×15mm×2mm (length×width×height). 66 Cu 25 Al 4 Ni 5 For amorphous alloys, the first step is to carry out mechanical polishing. First, use a nylon wheel for rough polishing for 1 minute, then use a hemp wheel and purple wax for medium polishing for 1 minute, and finally use a white cloth wheel and small white wax for 30 seconds. The second step is to remove wax. The zinc alloy dewaxing water sold at 80°C dewaxes for 2 minutes, and then rinses it with deionized water; the third step is degreasing, using 30g / L degreasing liquid prepared by Mai Demei degreasing powder at 30KHz Ultrasonic d...

[0043] This Example 2 is used to illustrate the zirconium-based amorphous alloy composite material provided by the present invention and its preparation method. In the preparation method in Example 2, the pretreatment of step 1 and the posttreatment of step 3 are the same as in Example 1 , the difference is only in step 2, which specifically includes the following steps:

[0044] Step 1, pretreatment: processing method is identical with embodiment 1;

[0045] Step 2. Plasma oxidation: Sodium sulfate, potassium nitrate, and ammonium oxalate are used as the main components to mix and prepare an electrolyte solution. The ratio of each component is sodium sulfate 10g / L, potassium nitrate 10g / L, and ammonium oxalate 5g / L. Heat and electrolyze liquid to 85°C constant temperature; the pretreated zirconium-based amorphous alloy substrate is used as the anode, and stainless steel is placed in the electrolyte as the cathode, and the zirconium-based amorphous alloy substrate is oxidized ...
