METHOD OF FORMING TANTALUM COATING FILM AND STRUCTURE FRAME MANUFACTURED BY THE SAME

摘要

Disclosed are a method for forming a tantalum coating film and a structural member manufactured by the same. According to the present invention, the method for forming a tantalum coating film includes: (a) a step of welding a tantalum wire and a base material; (b) a step of forming molten salt consisting of LiF, NaF, and K_2TaF_7, wherein the molten salt is to electroplate tantalum; (c) a step of inserting a platinum wire as a reference electrode and the tantalum wire and the base material as a work electrode, into the molten sa and (d) a step of electrodepositing tantalum metal to the base material by applying a current to the base material. The method for forming a tantalum coating film is to solve a problem in which a coating film is not formed due to the formation of an oxide film (TaO_x) and mixed-melting of a welding unit in electroplating of the molten salt by using a double welding method and controlling a concentration of a coating raw material.
