Abstract
The invention relates to the technical field of titanium metal anti-corrosion preparation, in particular to a titanium metal anti-corrosion coating preparation process by molten salt electrodeposition. A preparation method comprises the following steps that S1, NaCl, CaCl2 and TiO2 are subjected to drying treatment after being sufficiently ground, and then a dried mixture is heated and is subjected to constant-temperature heat preservation after being heated to a target temperature; S2, a carbon steel substrate and a high-purity graphite sheet are taken as a cathode and an anode in the electrodeposition process correspondingly and are connected with a titanium metal bar together correspondingly; S3, the carbon steel substrate of the cathode and the high-purity graphite sheet of the anode are put into a tube type resistance furnace correspondingly; S4, electrodeposition effect is performed; S5, after the deposition is finished, a carbon steel substrate deposition sample is put in boiling distilled water; and S6, finally, microwave oscillation is performed on the carbon steel substrate deposition sample. By means of the titanium metal anti-corrosion coating preparation process by themolten salt electrodeposition, the problem of not enough high purity of produced titanium metal in the molten salt electrodeposition process is solved, by means of the method provided by the invention, a good-quality titanium deposit layer is obtained on the carbon steel surface, the particle size is uniform, and the film forming property is good.
Description
technical field [0001] The invention relates to the technical field of titanium metal anticorrosion preparation, in particular to a process for preparing a titanium metal anticorrosion coating by molten salt electrodeposition. Background technique [0002] At present, the most common production process of titanium metal is still the Kroll method, but many scholars predict that this process will be replaced by the new molten salt electrolysis process in the near future. Molten salts are used as electrolytes to prepare metals. [0003] The FFC Cambridge method is known as the most promising technology to replace the Kroll method at present. The FFC Cambridge method was originally used to improve the purity of titanium metal and remove the residual oxygen in titanium metal. Later, it gradually developed into directly using titanium dioxide as raw material. A new method for preparing titanium metal by electrolysis. This process uses titanium dioxide powder as the raw material. ...
