摘要:
An article is coated with a multi-layer coating comprising a nickel layer, a chrome layer, a refractory metal layer, preferably zirconium layer, a sandwich layer comprised of a plurality of alternating layers of a refractory metal compound and a refractory metal compound layer, preferably zirconium nitride layer, and a refractory metal oxide layer or a layer comprised of the reaction products of refractory metal, oxygen and nitrogen. The coating provides the color of polished brass to the article and also provides abrasion protection, corrosion protection, and improved acid resistance.

An article is coated with a multi-layer coating comprising a nickel layer, a tin-nickel alloy layer, a non-precious refractory metal layer, a sandwich layer comprised of a plurality of alternating layers of non-precious refractory metal compound and of a non-precious refractory metal, a non-precious refractory metal compound layer, and a layer comprised of a non-precious refractory metal oxide or the reaction products of a non-precious refractory metal, oxygen and nitrogen.
摘要:
A faucet includes a first valve plate comprising a base material (18) and a strengthening layer (23) provided above the base material. An amorphous diamond material (30) is provided above the strengthening layer. The amorphous diamond material has a coefficient of friction that is lower than that of diamond-like carbon and has a hardness that is greater than that of diamond-like carbon. The strengthening layer (23) comprises at least one of tantalum, niobium or a compound, complex or salt of tantalum or niobium.
摘要:
An article is coated with a multi-layer coating comprising at least one nickel layer (13) deposited on the surface of the article (12), a palladium/nickel alloy layer (20) deposited on the nickel layer (13), a refractory metal, preferably zirconium, layer (22) deposited on the palladium/nickel alloy layer (20), a sandwich layer (26) comprised of alternating layers (28,30) of refractory metal compound and refractory metal deposited on the refractory metal layer (22), a refractory metal compound layer (32), preferably zirconium nitride, deposited on the sandwich layer (26), and a layer (34) comprised of a refractory metal oxide or the reaction products of a refractory metal, oxygen and nitrogen deposited on the refractory metal compound layer (32). The coating provides the color of polished brass to the article and also provides abrasion and corrosion protection.
