Abstract

This study suggests that sporadic failure of nitinol orthodontic wire is due to the presence of surface defects generated during manufacturing and not to the effects of corrosion. The flexural properties were evaluated for both control and corroded samples of nitinol wires and were not found to be statistically different. Fractured surfaces of control as well as corroded samples following bending were examined by scanning electron microscopy to determine the mode of failure.

摘要

本研究表明，镍钛正畸丝的偶发性失效是由于制造过程中产生的表面缺陷，而非腐蚀作用。对镍钛丝的对照样品和腐蚀样品的弯曲性能进行了评估，发现两者在统计学上并无差异。通过扫描电子显微镜检查弯曲后对照样品和腐蚀样品的断裂表面，以确定失效模式。
