Shape memory alloy smart material
WebbShape memory alloys (SMAs) are considered smart and innovative materials discovered as early as 1932 and, in 1960, were manufactured from nickel and titanium to exhibit better behaviour than any other element used in memory alloys. These polymorphic materials are composed of crystalline or chemical phases. WebbTo functionalize and improve the biocompatibility of the surface of a medical implant made of NiTi shape memory alloy and used in practice, a clamp, multifunctional layers composed of amorphous TiO2 interlayer, and a hydroxyapatite coating were produced. Electrophoresis, as an efficient method of surface modification, resulted in the formation …
