摘要:
A surface coating film includes, a base material which is a hard material; and an oxidation-resistance coating layer containing, as a main component, a complex oxide of Li and at least Al and covering a surface of the base material. Further, a method of manufacturing a surface coated member, includes, supporting a base material which is a hard material in a hermetic container with the use of a holder arranged in the container; arranging a complex oxide forming target containing Li and at least Al, as main components, in the container; feeding oxygen into the container; and forming an oxidation-resistance coating layer that covers the base material to obtain the surface coated member by effecting electric discharge between the complex oxide forming target as an anode and the holder as a cathode.
