| Research Abstract |
Argon ion Sputter-etching was applied to commercially supplied metals to form fine protrusions. The protrusions formed on the tool steels absorb more than 99% of visible light. The protrusions formed on the copper alloys absorb about 90% of near-infrared rays. The protrusions formed on a copper alloy reveals relatively good field emission characteristics. Press forming is applicable to a thin steel sheet with protrusions without damage by covering the protrusions with plastic sheets.
