Galling-free fine blanking of titanium plates by carbon-supersaturated tool steel punch

Abstract. The carbon supersaturated tool steel and high-speed steel punches were utilized to demonstrate that the titanium work materials were forged in high reduction of thickness and fine-blanked without adhesion of their fragments and deposition of their oxide debris particle. This galling free forging and fine blanking came from the in situ formation of the free carbon tribofilm only on the highly stressed interfaces between the punch/die and the titanium work. Under this in situ solid lubrication, the low frictional state was sustained to induce less bulging deformation of work during the forging process. The fine blanking of titanium plates advanced without adhesive wear and fractured regions on their sheared surface. The long life of tools was certified even in fine blanking of titanium and titanium alloy plates.
