Abstract
Neutron activation analysis was applied to the determination of elements Au , Cr, Fe, Ni and Zn released in NaCl solution and in a culture medium in wh ich gold coated studs were immersed for corrosion tests. The coating defect s and corrosion effects on the stud surfaces were studied by scanning elect ron microscopy and energy dispersive spectroscopy analysis. The cytotoxicit y assay of culture medium from corrosion test showed toxicity in a culture of mammalian cells, (C) 1999 Elsevier Science Ltd. All rights reserved.
