Appeal No. 2000-0049
Application 08/826,209
having a {100} crystallographic faceting layer and a non-{100}
crystallographic faceting layer. Claims 1 and 7 are
illustrative:
1. A method for making a diamond film coated wear part,
comprising the steps of:
providing a wear part;
depositing a first layer of polycrystalline diamond film
on said part with non-{100} crystallographic faceting;
depositing on the surface of said first layer a second
layer of polycrystalline diamond film having {100}
crystallographic faceting, said second layer having a
thickness sufficient to overgrow the roughness of said surface
of said first layer with a continuous film.
7. A method of making a wear component, comprising the
steps of:
providing a base surface;
producing a polycrystalline diamond film structure having
a first layer and a second layer on said first layer, said
first layer having non-{100} crystallographic faceting, and
said second
layer having {100} crystallographic faceting, said second
layer having a thickness sufficient to overgrow the roughness
of said surface of said first layer with a continuous film;
and
applying said diamond film to said base surface.
