Chemical Stability of Chromium Carbide and Chromium Nitride Powders Compared with Chromium Metal in Synthetic Biological Solutions
Figure 4
Release of chromium from powders of Cr-C, Cr-N and Cr-metal exposed for 168 h in different biological media expressed as the amount of chromium released per amount of chromium in the loaded powder (μg/μg), (a), and the released amount of chromium normalized to the surface area (BET). Reported literature data [1, 38] for Cr2O3 exposed at identical conditions is included for comparison. Error bars correspond to the standard deviation of triplicate samples.
