Abstract
A method of forming a wear resistant component includes providing a base material, depositing a strengthening layer on the base material, and vapor depositing an amorphous diamond layer on the strengthening layer.
Claims54
A method of forming a wear resistant component comprising:
- providing a base material;
- depositing a strengthening layer on the base material;
- and
- vapor depositing an amorphous diamond layer on the strengthening layer, the amorphous diamond layer having sp3 bonding of at least about 40%, a hardness of at least about 45 GPa, and an elastic modulus of at least about 400 GPa.

A method of producing a valve plate comprising:
- providing a strengthening layer on a substrate;
- and
- providing amorphous diamond on the strengthening layer;
- wherein the amorphous diamond has sp3 bonding of at least about 40%, a hardness substantially greater than that of diamond-like carbon, and an elastic modulus of at least about 400 GPa.

A method of forming a valve plate for a fluid control valve comprising:
- providing a substrate for a valve plate of a fluid control valve;
- depositing a strengthening layer on the substrate;
- and
- utilizing a filtered arc deposition process to deposit an amorphous diamond layer on the strengthening layer at a temperature below approximately 250° C.;
- wherein the amorphous diamond layer has sp3 bonding of at least about 40%, a hardness of at least about 45 GPa, and an elastic modulus of at least about 400 GPa.

A method of forming a valve plate for a fluid control valve comprising:
- providing a substrate to be utilized as a valve plate in a fluid control valve;
- depositing a strengthening layer on the base material that is harder than the substrate at a thickness sufficient to increase the scratch resistance of the valve plate;
- and
- vapor depositing an amorphous diamond material on the strengthening layer to a thickness of at least 100 nm, the amorphous diamond material having sp3 bonding of at least about 40%, a hardness of at least about 45 GPa, an elastic modulus of at least about 400 GPa, and a coefficient of friction that is lower than that of diamond-like carbon,
- wherein the amorphous diamond material is deposited at a lower temperature than is required for the deposition of polycrystalline diamond.

A method of forming a component for use in a faucet comprising:
- providing a valve plate comprising a base material;
- depositing a strengthening layer on the base material, the strengthening layer having a hardness that is greater than that of the substrate;
- and
- providing an amorphous diamond material on the strengthening layer, the amorphous diamond material consisting essentially of carbon and having a coefficient of friction that is lower than that of diamond-like carbon and a hardness that is higher than that of diamond-like carbon.
