Method for preparing zinc-titanium alloy at low temperature by taking titanium oxycarbide as anode

Abstract

The invention relates to a method for preparing zinc-titanium alloy at low temperature by taking titanium oxycarbide as an anode. The method comprises the following steps of: (1) dissolving anhydrous ZnCl2 in DMI, then adding TiCl4, and uniformly stirring to prepare ionic liquid; (2) forming an electrolytic tank system by taking the obtained ionic liquid as an electrolyte, and carrying out electro-deposition by adopting a three-electrode system, wherein the counter electrode, namely the anode, is the titanium oxycarbide; and (3) taking out a cathode after electro-deposition, cleaning to remove electrolyte adhered to the surface, and drying to obtain the zinc-titanium alloy on the surface of the cathode. The method is simple in process, reduces energy consumption and production cost, and reduces environmental pollution; and compared with metal and alloy prepared through high-temperature molten salt, the method has the advantages of being short in process, low in cost, easy to operate, capable of saving energy and environmentally friendly and has a great application prospect.

Problems solved by technology

The hot-dip plating method needs to be carried out at high temperature, so the energy consumption is high, the cost is high, and it pollutes the environment; although the electroplating method is not carried out at a high temperature, the process is complicated and highly corrosive to the equipment, and the coating is uneven; Both spraying and mechanical plating also have disadvantages such as high porosity, long production cycle, and low coating quality.
