摘要

Ni-59-65Cr26-23Mo11-9合金在pH为2.3、4.2或6.5的乳酸/盐水溶液中释放的镍量明显低于Ni66-85Cr15-13Mo7-0合金，持续1天，随后持续3天，总共持续33天。虽然镍的溶解度在pH值2.3和4.2时同样高(根据合金的类型在0.1微米/平方厘米d和222微米/平方厘米d之间变化)，但在pH值6.5时，从所有测试合金中溶解的镍最多为2微米/平方厘米d。

[Nickel release of dental alloys as a function of the pH value of the corrosive solution].

Ni-59-65Cr26-23Mo11-9 alloys released distinctly lower quantities of nickel in lactic acid/saline solutions at pH 2.3, 4.2, or 6.5 than type Ni66-85Cr15-13Mo7-0 alloys for a period of 1 day and, subsequently, periods of 3 days over a total period of 33 days. While nickel solubility was similarly high at pH 2.3 and 4.2 (varying between 0.1 microns/cm2 d and 222 microns/cm2 d depending on the type of alloy), a maximum of 2 microns/cm2 d of nickel dissolved from all tested alloys at a pH value of 6.5.
