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。When 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.
