Abstract
Immersing 15 commercial chromium-nickel casting alloys in 1% lactic acid, 0.05% HCl, and Ringer's solution for 7 days at 37℃, released metallic elements, the composition of these alloys were determined by inductively coupled plasma emission spectrometry.
The results indicated that the release of metallic elements in chromium-nickel alloys containing an excess of 14% chromium was decreased. The released metallic element concentration of only Ni in the tested chromium-nickel alloys was less than 1.0 mg/cm2. Among the 3 immersion solutions, the corrosiveness of 1% lactic acid was large, whereas that of Ringer's solution was below the limit of detection.
