[0053] Example 1
[0054] A preparation method of a zirconium alloy coating with high burn-up and long-life period, including:
[0055] (1) Pre-treatment: Place the obtained zirconium alloy matrix material in an ultrasonic container and wash with carbon tetrachloride and acetone for 10-20 minutes respectively, then ultrasonically clean with deionized water for more than 10 minutes, and use deionized water in the final stage rinse. The cleaned pipe samples are dried in a vacuum drying oven, and the drying temperature does not exceed 50°C. Clamp the pre-processed sample on the turntable of the coating equipment.
[0056] (2) Ion cleaning: vacuum the vacuum chamber of the coating equipment, and the vacuum degree reaches 1×10 -3 After Pa is above, a certain flow of argon is then filled to maintain the pressure in the vacuum chamber at 0.1-5 Pa. The bias voltage is adjusted to above -1000V for about 10-20 minutes, and the surface of the zirconium alloy pipe is bombarded by a high-speed...
