Influence of Dual Heat Treatment on the Metallurgy and Mechanical Behaviour of Diamond‐Like Carbon–Coated <scp>NiTi</scp> Rotary Systems: A Multimethod Investigation
The application of dual heat treatment during manufacturing significantly influenced the mechanical performance of the tested rotary NiTi instruments. Rainbow Ultra, subjected to sequential heat treatments, exhibited higher flexibility, cyclic fatigue resistance and cutting efficiency, whereas Rainbow One demonstrated greater torsional strength and buckling resistance.
