What nickel titanium alloy powder？ NiTi alloy powder is a shape memory alloy. Shape memory alloy is a special alloy that can automatically restore its plastic deformation to its original shape at a specific temperature. Its expansion rate is more than 20%, fatigue life reaches the 7th power of 1 * 10, damping characteristics are ten times higher than ordinary springs, and its corrosion resistance is better than the best medical stainless steel. Therefore, it can meet the needs of various engineering and medical applications and is a very excellent functional material. In addition to its unique shape memory function, memory alloys have excellent characteristics such as wear resistance, corrosion resistance, high damping and super elasticity. As the name implies, nickel-titanium alloys are binary alloys composed of nickel and titanium. Due to changes in temperature and mechanical pressure, there are two different crystal structural phases: austenite and martensite. During cooling, nickel-titanium alloy's transformation sequence is the parent phase (austenite phase) - R phase - martensite phase. R phase is rhombic, and austenite is the state when the temperature is high (greater than the same: the initial temperature of austenite) or when the load is removed (deactivation by an external force), cube; it is hard, and the shape is relatively stable.
Clinical application of nickel-titanium alloy wire NiTi spring: NiTi pushes spring and pulls springs are used in orthodontics. They are super elastic and suitable for orthodontic treatment to open up the space between teeth and pull them in different directions. NiTi spiral spring can produce a force of about 50g when extended for 1mm. NiTi spiral spring has high elasticity and can produce a relatively soft and stable continuous force when stretched. The force attenuation is very small; It can produce an ideal orthodontic force that meets the needs of clinical tooth movement. It meets the physiological requirements. The nickel-titanium wire tension spring has high elasticity and a low permanent deformation rate. Compared with stainless steel wire of the same diameter, its released orthodontic force is 3.5-4 times different. Therefore, in the application of an orthodontic treatment, patients not only have less pain and feel soft and lasting strength but also have less time for follow-up, which shortens the course of treatment and improves efficacy. It is a new excellent mechanical device in orthodontic treatment.
Classification of nickel-titanium alloy wires Evans and Durning classification Gradedthermodynamic: The TTR temperature is about 40 ℃ higher than the oral temperature. This way, when the nickel-titanium archwire is placed in the oral cavity, it is still in a multi-element state. The archwire is relatively soft. When the mouth contains hot water, there is austenite transformation. Therefore, the corrective force is weaker; It can be used as the initial arch wire for adult and periodontal patients. The copper nickel-titanium wire produced by Omcro Company and the Japanese low hysteresis L-H nickel titanium archwire has such properties.
