ABSTRACT:
An iron-based cutting tool, useful for machining aluminum-based workpieces at surface speeds at or in excess of 1000 sfm, is fabricated by (i) removing surface impurities from the surface of the cutting tool which will be exposed to crater wear during such machining, the removal being by sputtering or ion bombardment using the surface as a target thereby resulting in a cleansed activated surface; and (ii) depositing a single-phase crystal film of sputtered silicon carbide onto the cleansed activated surface.
The activation of the surface in step (i) is carried out by causing ionized argon to be accelerated against the surface maintained at about zero bias and the depositing of step (ii) is carried out to cause silicon carbide to be condensed onto the activated surface as a result of being dislodged from a silicon carbide target maintained at about zero bias for at least 300 minutes. The film of silicon carbide has a thickness in a range of about 1-4 microns, and the crystal orientation of such film is amorphous.
