Addition of boron to the TNZT alloy shifts the Ecorr value toward a more active direction and increases the icorr as well as ipass values significantly, and therefore deteriorates the corrosion resistance of the titanium alloys. In general, duplex aged TNZT samples show better corrosion resistance than other heat-treated TNZT or TNZTB samples.
