Abstract
A method of manufacturing a Ti material for a fuel cell separator includes rolling a Ti raw material of a pure Ti material or a Ti alloy material, deposition coating Ti ion particles on the Ti raw material by physical vapor deposition (PVD), and oxidation heat treating to form a conductive oxide layer of a TiO2-x(0<x<1) structure around the Ti ion particles deposited by the deposition coating. According to the present disclosure, the Ti material can be used to achieve both corrosion resistance and conductivity.
