The aim of this study was to characterize the electrochemical behavior and biocompatibility of pure titanium and a series of experimental Ti-(10-40) wt% Zr alloys.Except Ti-5Cr and Ti-10Cr alloys, the bond strengths of all the other Ti-Cr alloys exceeded the lower limit value in the DIN 13.927 standard for the 3-point bending test (25 MPa). In the Ti-Cr alloys, bond strength tended to increase as the Cr component increased.Under SEM observation, c.p. Ti surface exhibited the least amount of retained porcelain on the metal surface after debonding, and mainly adhesive bond failure. However, more traces of retained porcelain were observed on specimens that contained higher alloying elements, such as Ti-25Cr and Ti-30Cr alloys, attesting to a better mechanical performance.
