Abstract

This disclosure is directed to a fuser member having a hard, abrasion-resistant bare metal alloy surface for fuser assem-blies in office copier machines. The alloys which are desirable for providing the hard abrasion-resistant surfaces for fuser members include alloys of cobalt, molybdenum and silicon; alloys of cobalt, molybdenum, silicon and chromium; alloys of nickel, molybdenum, silicon and chromium; alloys of cobalt, molybdenum, chromium, silicon and nickel; and alloys of cobalt, molybdenum, chromium, silicon, nickel and copper. Exemplary of the alloys which may be used in accordance with this disclosure are those alloys having the trade designation "Tribaloy" and blends of "Tribaloy" and copper. These include Tribaloy 100, Tribaloy 400, Tribaloy 700 and Tribaloy 800. Tribaloy is a E.I. duPont trademark.

This disclosure is directed to a fuser member having a hard,
abrasion-resistant bare metal alloy surface for fuser assem-
blies in office copier machines. The alloys which are
desirable for providing the hard abrasion-resistant surfaces
for fuser members include alloys of cobalt, molybdenum and
silicon; alloys of cobalt, molybdenum, silicon and chromium;
alloys of nickel, molybdenum, silicon and chromium; alloys of
cobalt, molybdenum, chromium, silicon and nickel; and alloys
of cobalt, molybdenum, chromium, silicon, nickel and copper.
Exemplary of the alloys which may be used in accordance with
this disclosure are those alloys having the trade designation
"Tribaloy" and blends of "Tribaloy" and copper. These include
Tribaloy 100, Tribaloy 400, Tribaloy 700 and Tribaloy 800.
Tribaloy is a E.I. duPont trademark.

Preferred f user members include cylindrical rolls, flat
plates, curved plates, belts and the like having at least an
outer surface of the hard, abrasion-resistant metal alloy. To
form the alloy at least upon the surface of the fuser member,
the particular alloy may be flame or plasma sprayed, electro-
plated, welded, a sleeve force fit upon a base member, and the
like; and the base member itself may comprise the alloy and
under such circumstances the surface thereof comprises the
hard, abrasion-resistant metal alloy of this disclosure.

The hard, abras...
