Document Type and Number:
WIPO Patent Application WO/2018/157867
Kind Code:
A1
Abstract:
A surface processing method for a tantalum spinning head, comprising the following steps: (a) forming a layer of Ta2O5 film on a tantalum spinning head; (b) optional polishing: polishing the fibre discharge surface of the tantalum spinning head having undergone processing in step (a) to rub off the Ta2O5 film on the surface of the fibre discharge surface; and (c) film plating: using a molten salt electrochemical method to perform film plating on the tantalum spinning head having undergone processing in step (b) to form a film layer containing a lithium compound. A surface processing method for a tantalum spinning head, comprising the following step: using a molten salt electrochemical method to perform film plating on the tantalum spinning head to form a film layer containing a lithium compound, the film plating temperature being 250℃-430℃. A tantalum spinning head acquired by means of surface processing using the aforementioned method.
