Comparison of corrosion resistance and apatite-forming ability of NiTi treated by different low-temperature methods

Characteristics of Anodized Layer in Investment Cast Ni50Ti50 Shape Memory Alloy

“…However, the anodized layer was visually observed as white color representing the maximum saturation of the anodized layer as discussed earlier. This means the deposited film is amorphous which is in agreement with previous pieces of work [14,15].…”

A study on the corrosion fatigue behaviour of laser-welded shape memory NiTi wires in a simulated body fluid

“…process [7]. Such changes can be either beneficial or harmful to NiTi depending on the type of process and processing conditions.…”

Effect of anodization and annealing on corrosion and biocompatibility of NiTi alloy

“…Oxygen evolution at the anode decreases the pH of the solution, which in turn, accelerates the dissolution of nickel [14]. The growth and the mechanism of anodization, and its characteristics in simulated body fluids are studied in detail by various researchers [17][18][19][20]. In general, as-anodized NiTi surface is amorphous in nature and post treatment such as annealing or hydrothermal treatment is often followed, for the development of crystallinity [15].…”
