Description
Technical Field

Background
In the practical application process, Q235 steel material is easy to corrode in high-temperature oxidation and strong acid medium, and if a metal matrix is exposed to marine environment for a long time, surface lattices can be moved, chemical corrosion can be caused, and serious consumption and breakage phenomena can be generated, so that great waste of material can be caused, and serious economic loss can be generated. In recent years, with the development of industrial production, new requirements for corrosion resistance of workpieces are made, and the limitations of conventional materials are exposed, and there is a necessary trend in developing new hot dip coating materials. At present, Zn-Al is still used as a main material in hot dip coating, and the corrosion resistance and the mechanical property of the coating are improved to the top. However, no application report exists for the Zn-Cu-Ti alloy coating at present, not to mention the hot dip coating with Zn-Cu-Ti-Ce. The rare earth element cerium (Ce) is prone to be enriched on the surface layer, and a dense Ce2O3 oxide film is easily formed on the surface of the coating. Research shows that 0.05-0.2% of Ce is added into zinc bath to delay the expansion of brittle alloy layer obviously, while the Sandelin effect of active steel is effectively inhibited after 0.04% of Ti and 0.02% of Ce are added into zinc solution simultaneously, the micro-hardness and tensile strength of Zn alloy can be increased by Cu compound phase, and the toughness of alloy can be improved by Ti compound phase.
The hot dip plating Zn-Cu-Ti-Ce alloy plating layer not only has high corrosion resistance and mechanical property, but also has the cathode electrochemical protection effect of the zinc-aluminum plating layer, and has important application prospect in the aspect of engineering structure corrosion prevention. However, related research work is hardly carried out, the appearance of the hot dip coating Zn-Cu-Ti-Ce coating is not clear, and the influence of the Ce content on the performance of the Zn-Cu-Ti coating is not clear.
