Abstract

The invention discloses a fastness rose gold target and a preparation method thereof. The fastness rose gold target contains Au, Ir and Cu. According to the fastness rose gold target, the iridium (Ir) is used for replacing an Ag element one of main elements in rose gold to form Au-Ir-Cu series rose gold. According to the fastness rose gold target, the wear resistance and the oxidation resistance of a film layer are improved, the fastness effect is effectively improved, and the service life and the use effect of a decoration are prolonged.

Description

technical field [0001] The invention relates to a rose gold target material and a preparation method thereof, in particular to an anti-tarnish rose gold target material and a preparation method thereof. Background technique [0002] It has become the mainstream process of modern decorative plating to replace the traditional water electroplating with magnetron sputtering to form a rose gold film. When the gold content is generally not more than 75%, the obtained film layer is prone to oxidation, wear and discoloration, which seriously affects the use effect and life of the decoration. Contents of the invention [0003] The object of the present invention is to overcome the defect that the rose gold film layer is easy to change color in the prior art, and provide an anti-tarnish rose gold target. [0004] In order to realize the above-mentioned purpose of the invention, the present invention provides the following technical solutions: [0005] Anti-tarnish rose gold target...
