Description

technical field [0001] The invention belongs to the field of metal electrodeposition, in particular to a method for electrodepositing titanium. Background technique [0002] As a strategic light metal, titanium has the advantages of high specific strength and strong corrosion resistance. It is often used in submarines and aircraft, and plays a huge role in the fields of navigation and aviation. Electrodeposition of titanium on the metal surface can play a role in protection and corrosion resistance. Applied in marine, seawater corrosive environments, etc. [0003] The discharge potential of metal titanium is low, and it is difficult to realize the deposition of titanium. At the same time, the electroplating technology of titanium is not mature and perfect. At present, the commonly used methods are as follows: one is the arc ionization electroplating method, which uses metal titanium to ionize into titanium ions in vacuum or inert gas and then bombards the cathode for electr...
