Embodiment 1

[0080] Embodiment one is with nano-rose gold / nanometer Al 2 o 3 Multilayer film is taken as an example, the rose gold target and Al 2 o 3 ceramic target.

[0081] 1) Furnace vacuuming: put the cleaned rose gold ornaments into the rotating hanger in the furnace, and draw a background vacuum of 3--6x10 -3 Pa; if the last process is to complete the ion-plating imitation rose gold (TiCN) coating on stainless steel and brass ornaments in this furnace, stop the titanium target, stop supplying nitrogen and acetylene, fill Ar gas to 5Pa, 7 minutes, stop For Ar, background vacuum up to 4x10 -3 Pa.

[0082] 2) Glow ion cleaning: fill with Ar gas 2Pa, turn on the pulse bias voltage, --600V, duty cycle 50%, and glow cleaning for 5 minutes.

[0083] 3) Play transition layer

[0084] For rose gold jewelry, fill with Ar gas 3x10 -1 Pa, bias voltage--80v, turn on the rose gold cathode arc source (50A) and DC magnetron sputtering rose gold target (3A) at the same time, mix plating for ...

Abstract

The invention discloses a gold product surface nano multi-layer composite anti-scratching film. The gold product surface nano multi-layer composite anti-scratching film is characterized in that the surface of a gold plating layer of a gold plating product or a gold product is covered with a transition layer, a nano multi-layer structure formed by at least one group of nano multi-layer composite protection film units, a Si transition layer and an AF anti-fingerprint film on the outermost layer sequentially from inside to outside, and each group of nano multi-layer composite protective film units consists of a nano transparent dielectric layer and a nano gold layer covering the nano transparent dielectric layer. The invention also relates to a preparation method of the film. The nano multi-layer composite anti-scratching film on the surface of the gold product prepared by the method well solves the problem that a gold plating layer on gold, gold ornaments or stainless steel, brass and the like is not resistant to scratching.

Description

technical field [0001] The invention relates to a surface ion-plated protective film of a gold product (or a gold-plated layer of a gold-plated product), in particular to a nano-multilayer composite anti-scratch film on the surface of a gold product. The invention also relates to a method for the preparation of said membrane. Background technique [0002] All kinds of gold and rose gold jewelry have always been loved by people, but gold or gold-plated jewelry is relatively soft, and the surface is prone to scratches and scratches after being bumped and rubbed during wearing, which will affect its dazzling beauty. For a long time, people have worked hard to improve the scratch resistance of gold. There are two ways: one is alloying, adding various alloying elements to Au, including precious metals and light and heavy rare earths, but the effect is not ideal, or the hardness can be improved. It is not big, or the original color tone is changed; the second is to coat the surfa...
