Abstract

The invention relates to a magnetic control spattering rose gold target and a preparation method thereof, which is characterized in that the components of the rose gold target by weight percent are as follows: 65 weight percent to 78 weight percent of gold, 16 weight percent to 33 weight percent of copper, 0.01 weight percent to 4 weight percent of yttrium, 1 weight percent to 7 weight percent of zinc, 0.001 weight percent to 1.2 weight percent of cobalt, 0.001 weight percent to 0.2 weight percent of stibium and 0.02 weight percent to 5 weight percent of indium. The preparation method comprises the following steps: the copper and the cobalt are heated and melted, the yttrium, the zinc, the stibium and the indium are added into the melted cooper and cobalt, to be refined for 3min under 1400 DEG C to 1450 DEG C, and the intermediate alloy material is obtained after conventional surface milling, rolling and shearing; the gold is heated and melted, and the prepared intermediate alloy material is added into the melted gold to be refined for 5min under 1200 DEG C to 1300 DEG C; the magnetic control spattering rose gold target prepared by the invention can eliminate the environment pollutin and product oxidability caused by a galvanic plating process, has stable performance and extremely good decoration effect.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, in particular to a magnetron sputtering rose gold target and a preparation method thereof. Background technique [0002] The color of rose gold is pink, and its gorgeous color and charming pastel tone have always been favored by people. However, the traditional rose gold process is realized by water electroplating process. This process is easy to achieve color, but it is very easy to oxidize and has poor surface wear resistance, and it is easy to cause environmental pollution. With the development of modern vacuum magnetron sputtering technology, how to sputter rose gold in a vacuum furnace, and achieve the purpose of anti-oxidation, anti-sulfurization, high hardness and good wear resistance. It is a wish that people have long expected to realize. Contents of the invention [0003] Aiming at the problems of the prior art, the present invention provides a magnetron sputtering rose gold targ...
