The effects of dual Zr & N plasma immersion ion implantation (PIII) on the corrosion behavior of WE43Mg alloy are evaluated in simulated body fluid (SBF) and cell culture medium (cDMEM). Zr & N PIII improves the corrosion resistance of WE43 which exhibits smaller i(corr), larger R-1 & R-2, smaller CPE2, and larger phase angle maxima in SBF and cDMEM. The Zr & N PIII WE43 samples exhibit 12-folds decrease in i(corr), in SBF and 71-folds decrease in i(corr) with near capacitive EIS in cDMEM. Analysis of the corrosion products reveals calcium phosphate. (C) 2014 Elsevier Ltd. All rights reserved.
