Abstract

The invention discloses a preparation method of a Zn-Cu-Ti-Mg alloy for thermal spraying, that is, a resistance furnace is used to prepare Zn-10Cu, Zn-3Ti and Zn-5Mg intermediate alloys, and an induction melting furnace is used to prepare Zn- 0.75Cu-0.15Ti-(0.1-0.2)Mg alloy, Zn-0.75Cu-0.15Ti-(0.1-0.2)Mg alloy wire with diameter of 3mm was prepared by extrusion and 7-pass rolling process. The advantages of the invention: on the one hand, a small amount of Mg element is added to the Zn-Cu-Ti alloy to improve the corrosion resistance of the alloy, and on the other hand, the problem that the Zn-Cu-Ti alloy wire is difficult to be industrialized is solved.

Description

technical field [0001] The invention relates to the technical field of alloys and thermal spraying materials, in particular to a preparation method of a Zn-Cu-Ti-Mg alloy for thermal spraying. Background technique [0002] With the development of the bridge business, bridge steel structures will be used in coastal areas with harsh environments and cold areas with lower temperatures, or bridges with larger span requirements. Because the bridge steel structure will always bear the dynamic load and static load, it also works in the wind, rain and humid environment for a long time. It is susceptible to various forms of damage such as stress, fatigue, corrosion, etc., resulting in material failure and damage to the bridge structure. It may cause safety accidents or economic losses. Therefore, improving the corrosion resistance of bridge steel structures is of great significance to the construction of bridge cables. It is a common method to thermally spray a layer of metal or a...
