摘　　要：分别采用磁控溅射和电镀工艺在18K金表面镀铑,并从膜层性能、生产效率、设备成本、材料投入与利用率等方面进行对比。结果表明,与电镀铑层相比,磁控溅射铑层的颜色与耐蚀性非常接近,晶粒尺寸和硬度略优,可以满足首饰膜层性能要求,且总体生产效率和安全环保方面更优。但是磁控溅射工艺存在设备和靶材一次性投入大,靶材的利用率不高,对首饰坯件结构的敏感性更高,以及镶嵌首饰的宝石表面会沉积膜层等问题。因此,在贵金属首饰生产中应用磁控溅射镀铑工艺时,可通过改进移动磁场、靶材结构等途径来提高靶材利用率,在设计产品结构和制定生产工艺时要考虑改善镀层均匀性的措施,并对镶嵌首饰上的宝石表面预先做好屏蔽。Rhodium films were deposited on 18k gold by magnetron sputtering and electroplating,respectively.The two processes were compared in terms of film properties,production efficiency,equipment cost,as well as material input and utilization efficiency.The results showed that as compared with the electroplated film,the magnetron-sputtered film has quite similar color and corrosion resistance,and a little better grain size and hardness,whose properties can meet the requirements of coatings on jewelry.The magnetron sputtering process is superior in overall production efficiency,safety,and environmental friendliness,but confronts with several problems,such as high initial investment on equipment and target material,low utilization efficiency of target material,high sensitivity to jewelry structure,and undesirable deposition on gem surface.Therefore,to apply magnetron sputtering in the production of precious metal jewelry,the utilization efficiency of target material should be improved by optimizing the design of moving magnetic field and the structure of target,some measures to improve the film uniformity should be considered in designing the product structure and developing the production process,and the gem surface should be shielded in advance for the inlaid jewelry.
