The amount of Ni and Cr released from specimens coated with gold was much fewer than those from unplated specimens (P .05), which meant the stability of Ni-Cr alloy on the surface was improved. The biocompatibilities of gold-coated Ni-Cr alloy were better than the uncoated alloy, though there was no difference in biological ranking.
