Abstract

ß-SiC coating die and punch were employed for forging of titanium wire to triangular bar in high reduction of thickness by 35 %. CNC (computer numerical control) stamper was utilized to describe the elasto-plastic behavior of titanium wire in dry forging. Precise analyses on the contact interface between SiC coating and titanium work were made to investigate the mass transfer of metallic titanium as well as titanium oxide debris particles onto SiC coating surface. In particular, element mapping and Raman spectroscopic analyses were performed to describe the formation of thin titanium oxide film as well as the agglomeration of unbound carbon on the SiC coating punch.
