a coating on said low alloy steel substrate, said coating
selected from the group consisting of chromium nitride, zirconium
nitride, molybdenum nitride, titanium-carbon-nitride, or
zirconium-carbon-nitride;
wherein said component is adapted to be exposed to a fluid
within said fuel injection system and said component is further
movable within said fuel injection system relative to an adjacent
component within said fuel injection system.
33. A component in a fuel injection system comprising:
a low alloy steel substrate;
a coating on said low alloy steel substrate, said coating
selected from the group consisting of titanium containing diamond
like carbon, chromium containing diamond like carbon, or tungsten
containing diamond like carbon;
wherein said component is adapted to be exposed to a fluid
within said fuel injection system and said component is further
movable within said fuel injection system relative to a second
component.
In the respective rejections, a patent to Djordjevic is
proposed to be modified based upon the teachings of Tsuchiya and
Young, the teachings of Tsuchiya and Little, and the teachings of
Tsuchiya, Young, and Little.
The patent to Djordjevic discloses a fuel injection pump
(Fig. 3) with a pump body and plungers being made of a suitable,
wear resistant steel alloy. The Tsuchiya reference teaches a low
alloy steel sleeve 4 between a bearing and a journal portion of a
rotor (Fig. 1). The Young patent discloses a piston ring or
