ABSTRACT:
A wear resistant component for a faucet valve includes a substrate comprising a base material and a strengthening layer provided above the substrate in an amount sufficient to improve abrasion resistance of the substrate. The strengthening layer includes at least one material selected from the group consisting of tantalum, chromium, zirconium, and tungsten. The wear resistant component also includes a layer that includes amorphous diamond provided above the strengthening layer, the amorphous diamond having sp3bonding of at least about 40%, a hardness of at least about 45 GPa, and an elastic modulus of at least about 400 GPa.
