Nanostructured TaxC interlayer synthesized via double glow plasma surface alloying process for diamond deposition on cemented carbide

- TaxC interlayer was creatively obtained on WC-Co by DG-PSA for diamond deposition.
- The interlayer with a flower-shaped surface consisted of Ta2C and TaC nanocrystal.
- TaxC interlayer had a superior adherence because of gradual element distributions.
- The samples' surface microhardness is increased caused by nanostructured interlayer.
- TaxC interlayer improved diamond adhesion on WC-Co by suppressing Co diffusion.
