考察不同组成及制备工艺对合金饰品镍释放量的影响

镍被广泛应用于日常使用的合金饰品中,镍的释放会引起皮炎等症状.针对不同组成及制备工艺的合金饰品进行了镍释放量的考察,表明相同基材的合金饰品,随着镍含量的增加,镍释放量增加;相同镍含量的基材,应用冲压工艺制备样品的镍释放量值低于失蜡浇铸工艺制备样品的镍释放量值.贵金属的加入能有效抑制镍释放量.

Effects of Different Compositions and Preparation Methods on Nickel Release in Alloy Adornments

Nickel is widely used in a broad range of products. It is shown that when skin has contact with these materials on a daily basis may cause nickel allergy. In accordance with the different compositions and preparation methods for the preparation of alloy adornments, the nickel release was tested. The results suggested that the nickel release increases with the increasing nickel contents of the same base material alloy adornments, the nickel release of alloy adornments produced by stamping process is lower than those produced by the lost wax casting process with the same nickel content. The amount of nickel release is significantly affected by the addition of noble metals.
