Embodiment 1
[0024] A method for preparing a corrosion-resistant cerium-containing Zn-Cu-Ti coating, comprising the following steps:
[0025] (1) Select high-quality sponge titanium and pure copper particles as raw materials for a ratio of 1:1, and use a vacuum arc melting furnace with electromagnetic stirring conditions for melting to prepare a Cu-50Ti master alloy.
[0026] (2) Using pure copper particles, pure zinc and pure cerium as raw materials, Zn-10Cu and Zn-3Ce master alloys are prepared by using a resistance furnace, the melting temperature is 650 ° C, the holding time is not less than 5 hours, and several times are stirred during the holding process .
[0027] (3) With pure Zn, Cu-50Ti, Zn-10Cu and Zn-3Ce intermediate alloy as raw materials, utilize resistance furnace to prepare Zn-0.75Cu-0.15Ti-0.1Ce immersion plating solution, first Zn block is melted during smelting, selected The temperature is about 650°C. After the Zn block is completely melted, the master alloy is added a...
