Stress Corrosion Cracking of NiTi Orthodontic Wires in Sodium Fluoride Solution

Abstract:

The influence of fluoride on stress corrosion cracking (SCC) of NiTi orthodontic wires was investigated using slow strain rate test (SSRT) and scanning electron microscopy (SEM). The results indicated that fluoride significantly accelerated the stress corrosion cracking of NiTi orthodontic wires. The fractographies of NiTi orthodontic wires exhibited striation pattern.
