  • 降低含镍白色金合金首饰镍释放率方法的探讨……孙永军,张凤霞,娄来常,李桂华,曹永建,李 婷
  • 摘 要:长期佩戴含镍白色金合金首饰,释放的镍离子会引起皮肤过敏。目前主要是通过控制首饰中的镍释放率来降低镍过敏问题,镍释放率越低,首饰越安全。探讨了降低含镍白色金合金首饰镍释放率的2种途径:材料“彻底改造法”和材料表面“局部改良”法,并对降低含镍白色金合金首饰镍释放率的研究重点及发展方向进行了展望。

    Discussion on methods of reducingthe nickel release rate of nickel-containing white gold alloy jewelry……Sun Yongjun,Zhang Fengxia,LouLaichang,Li Guihua,Cao Yongjian,Li Ting

    AbstractWhen nickel-containing white gold alloy jewelry is in prolonged contact with human skin,the release of nickel ions can cause skin allergies.At present,the nickel allergy problem is mainly regulated by controlling the nickel release rate in jewelry,the lower the release rate of nickel,the more secure the jewelry.Two methods that reduce the nickel release rate of nickel-containing white gold alloy ornaments were discussed:material "reforming" method; "local improvement"method of material surface.The research focus of reducing the nickel release rate of nickel-containing white gold alloy jewelry and its development direction were also prospected.

    Keywords:nickel-containing white gold alloy jewelry; nickel release rate; corrosion resistance performance; material modification; heat treatment</s
